Health for All is a biding for all nations under the Alma Ata Declaration, the provision of quality healthcare services to the people of Pakistan, Pakistan is struggling with a double burden of disease, which means that the country is facing a significant burden of infectious diseases alongside an increasing epidemic of non-communicable diseases. Hepatitis C is a significant public health concern in Pakistan, with the prevalence rate currently standing at 7.5% with 10 million infected cases, out of 60 million hepatitis C cases globally. The impact of the disease on the population is significant, and it poses a serious challenge to the nation's healthcare system. Viral Hepatitis, though infectious, can also transition into chronic illness. i.e. liver cancers, increasing the financial burden on both our public and health systems. However, the Government of Pakistan, with the highest political will has launched an ambitious initiative to eliminate Hepatitis C infection in the country. This initiative aims to screen, test, and treat at least 50% of the eligible population, a step towards significantly reducing the burden of Hepatitis C in Pakistan.
Pakistan has the highest prevalence of Hepatitis-C in the world, surpassing Egypt, which successfully eliminated the disease through a concerted national effort. "Our goal is to replicate Egypt's success by ensuring mass screening, awareness, and access to effective three-month oral treatments."
Government of Pakistan has taken a crucial step by investing in the hepatitis C program which will help avert significant morbidity and mortality due to complications as well as financial burden on the health systems Hepatitis C Elimination Program as Public Sector Development Programme (PSDP) project in collaboration with all four provinces. Timely screening and treatment are essential in preventing liver failure and liver cancer among affected individuals.
This initiative aims to ensure early detection through widespread screening, PCR testing, and treatment - all provided free of cost.
The project is set to run from July 2024 to June 2027 with domestic funding as a PSDP project covering all four provinces, ICT and federating regions. The initiative targets a substantial portion of Pakistan’s population, focusing on individuals aged 12 years and above, with a goal to screen and treat 50% of the eligible population (approximately 82.5 million people).
The success of this initiative hinges on a well-coordinated effort between the federal and provincial governments. The federal government will play a pivotal role by providing essential commodities for the program. This includes 100% of the Rapid Diagnostic Test (RDT) kits for screening, 30% of the testing (PCR), and 50% of the medicines required for treatment. Additionally, the federal government will establish a Project Management Unit (PMU) to oversee the implementation of the program, ensuring that key performance indicators (KPIs) are met and providing the necessary support to the provinces.
The provincial governments will strengthen health facilities to enable effective screening, testing, and treatment. They will be responsible for training the necessary healthcare workforce, including doctors, nurses, laboratory technicians, and data entry officers. Provinces will also take the lead in raising public awareness about Hepatitis C, ensuring that communication strategies are in place to promote prevention, control, and treatment. The provinces will be tasked with deploying human resources where needed and covering the treatment costs for 50% of positive cases.
Since the devolution of health services in 2011, provincial governments have been managing hepatitis control programs. These programs are already operational and have made strides in addressing Hepatitis C and B. Key initiatives include:
- Free screening, testing, and treatment services for the general population
- Hepatitis B vaccination (except for infants and children under five years of age)
- Awareness campaigns aimed at the prevention and control of viral hepatitis
The provinces, including Punjab, Sindh, Khyber Pakhtunkhwa (KP), and Balochistan, have established hepatitis clinics across various healthcare facilities, such as district and teaching hospitals, rural health centers, and dispensaries. These clinics offer screening, PCR testing, and treatment. For example, Punjab alone has 243 hepatitis clinics in place. Additionally, waste management systems have been set up at hospitals, and vaccination and treatment camps are organized to reach underserved areas, including prisons and refugee camps.
Federal and Provincial Collaboration for Success
A crucial aspect of this program is the coordination between federal and provincial authorities. The Prime Minister will chair a National Task Force (NTF) to ensure that the Hepatitis C elimination initiative stays on track. The Technical Committee, led by experts Prof. Saeed Akhtar and the highest level leadership from MONHSRC, will provide strategic oversight and guidance on program implementation. A well-defined procurement and implementation plan will ensure that the program is executed effectively, with ongoing monitoring and evaluation to track progress.
The development of a National Electronic Medical Records (EMR) system for Hepatitis C is a significant innovation that will facilitate better management and reporting of patient data, ensuring that the program is not only comprehensive but also efficient and transparent.
Challenges and Solutions
One of the primary challenges in addressing Hepatitis C in Pakistan is the need to expand screening, testing, and treatment services, especially in remote areas. Additionally, tackling stigma and misinformation about Hepatitis C is a key component of the public health strategy. The collaboration between federal and provincial governments, supported by robust funding, training, and awareness efforts, will be crucial in overcoming these challenges.
The provision of free screening and treatment, combined with a strong communication campaign, will help to ensure that a larger portion of the population is reached. Further, engaging the private sector and ensuring that healthcare workers are well-trained and equipped with the necessary resources will contribute to the program's overall success.
Recently program has been successfully piloted in two districts of Gilgit Baltistan District Shigar - UC Markunja District Diamer - UC MC ChilasThe Hepatitis C elimination initiative in Pakistan marks a significant step forward in the country’s battle against viral hepatitis. With a well-coordinated effort, sufficient funding, and the active involvement of both federal and provincial governments, the goal of eliminating Hepatitis C in the country by 2027 is achievable. By reaching out to vulnerable populations, improving healthcare infrastructure, and promoting awareness, this initiative has the potential to reduce the prevalence of Hepatitis C and improve the health outcomes of millions of Pakistanis.
Early detection can save lives.

Pathogen genomic surveillance, the ability to track changes in the genetic makeup of viruses, bacteria, and other microbes has become an indispensable tool in modern public health. While high-income countries have long used this technology to detect outbreaks, trace transmission chains, and guide interventions, many low- and middle-income countries (LMICs) have struggled to adopt it due to high costs, complex technical requirements, and limited bioinformatics capacity.
Prior to COVID-19, Pakistan had no in-country genomic sequencing capacity for public health purposes. The pandemic changed everything. It was not only a wake-up call but also a catalyst for a sweeping transformation. In response to the crisis, Pakistan rapidly established its first national genomic surveillance infrastructure at the National Institute of Health (NIH) enabling real-time tracking of SARS-CoV-2 variants for the first time in our history.
This blog reflects on how genomics reshaped Pakistan’s pandemic response, how we continue using it for emerging threats like Mpox and why embedding it in national policy is essential for future epidemic preparedness.
COVID-19: The Catalyst for Genomic Self-Reliance
Before 2020, genetic sequencing in Pakistan was largely confined to research institutions, with limited use in public health. The Virology Department at NIH had basic Sanger sequencing capacity, but this older technology lacked the throughput and speed needed for real-time surveillance of evolving pathogens. In many cases, clinical samples had to be shipped abroad causing delays, incurring costs, and raising biosecurity concerns.
The COVID-19 pandemic exposed this gap dramatically.
Recognizing the urgent need, NIH with technical support from the U.S. Centers for Disease Control and Prevention (CDC) established Pakistan’s first Next-Generation Sequencing (NGS) facility for public health in May 2020. I was fortunate to be part of the capacity-building journey, receiving training and helping operationalize this breakthrough.
The impact was immediate. In June 2020, the newly operational NGS facility detected the D614G mutation, an early indication of variant-driven transmission during Pakistan’s first COVID-19 wave. By the time the Alpha variant (B.1.1.7) emerged, our capacity had matured. Although national case numbers were declining, our sequencing data showed a sharp rise in Alpha cases. This early warning, reported to the National Command and Operation Centre (NCOC), allowed Pakistan to anticipate rather than simply react to the pandemic’s third wave.
This marked a turning point: for the first time, genomic evidence was shaping national policy in real time.
Subsequent waves driven by Delta, Omicron, and its sub-lineages were tracked in similar fashion. More than 7,000 SARS-CoV-2 genomes have since been submitted to GISAID, a number unimaginable just five years ago. But beyond numbers, this data informed decisions, guided testing and containment strategies, and cemented the role of genomics in Pakistan’s public health response.
Though most of these sequences were generated by the lab I lead, credit is due to our partners at Aga Khan University which had Sanger sequencing capacity before the pandemic and developed NGS capabilities during COVID-19—and the provincial public health labs in KP, Punjab, and Sindh, which established NGS capacity from scratch, having lacked even basic Sanger sequencers prior to the pandemic. This transformation proves that, with political will and investment, even complex systems can be built quickly and effectively.
Beyond COVID-19: Expanding Genomic Surveillance
Our genomic capacity is no longer limited to COVID-19.
In April 2023, during the global Mpox (monkeypox) public health emergency of international concern (PHEIC), NIH identified the first national case as Clade IIb, Lineage A.2.1. Later, in December 2024, NIH also reported the more virulent Clade Ib variant—an event made possible only through local sequencing.
These efforts provided timely answers to policymakers: identifying clades (critical for risk stratification), tracing virus importation routes through phylogenetics, and shaping national containment efforts.
Our work has since expanded to vector-borne diseases such as dengue virus and Crimean-Congo hemorrhagic fever virus (CCHFV). NIH is also leveraging genomics to study rotavirus, measles, mumps, influenza, and RSV, underscoring its broader utility for endemic and emerging threats.
Challenges on the Genomic Frontier
Despite this remarkable progress, several challenges remain:
1. Lack of sustained national ownership: Much of Pakistan’s genomic work has been supported by donors and development partners. Without federal and provincial governments investment, the current system risks collapse once external support fades.
2. Shortage of trained bioinformaticians: While NIH and AKU have built technical capacity, provincial labs still face acute human resource and infrastructure gaps in bioinformatics.
3. Delayed implementation of national strategy: Although Pakistan launched its National Genomic Surveillance Strategy in February 2023, implementation has been slow. To address this, I recently led a national revision process to incorporate a clear implementation plan and One Health lens, identifying priority pathogens and enabling cross-sector coordination.
4. Bridging science and policy: Our scientific community must learn to translate genomic data into actionable public health intelligence. Sustainability will depend not just on technology, but on the ability to influence decisions and protect lives.
The Way Forward: Institutionalizing Genomic Surveillance
We now stand at a crossroads.
Pakistan must evolve its pandemic-driven investments into permanent public health assets. This includes:
- Establishing a national pathogen genomics framework
- Investing in infrastructure, workforce development, and bioinformatics
- Integrating genomics with One Health, antimicrobial resistance (AMR), and disease elimination programs
- Leveraging platforms like IPSN, WHO Technical Working Groups, and South-South collaboration
“Pakistan’s pandemic investments must now evolve into a permanent public health asset.”
Conclusion: From Pandemic to Preparedness
Pakistan’s journey from zero capacity to regional leadership in genomic surveillance is nothing short of remarkable. But the work is far from over.
Genomics is not just a laboratory tool, it is a core public health strategy. As threats evolve, so must our systems. By embedding genomics into national health security and policy reform, Pakistan can ensure it is not only ready for the next pandemic, but also better equipped to protect its people from ongoing threats.
The path from crisis to capacity has been challenging—but it has shown us what’s possible when science, leadership, and collective urgency converge to build resilient public health systems.

Meningitis is a life-threatening infectious disease that can affect all age groups, but especially neonates and children less than 5 years old. Bacterial meningitis can be caused by several pathogens, but among neonates, Group B Streptococcus (GBS, Streptococcus agalactiae) stands out as the leading causative agent of meningitis. The greatest meningitis burden worldwide is reported in children, with 112,000 deaths and 1.28 million cases in 2019. Considering the etiology of neonatal meningitis, viruses are responsible for 37.1% of total cases, followed by GBS (20.4% of total cases) and Neisseria meningitis (9.7% of total cases). GBS can colonize the lower reproductive tract of up to 40% of pregnant women worldwide and is associated with both vertical and horizontal modes of transmission. According to the World Health Organization (WHO), 21.7 million pregnant women are colonized by GBS each year, which leads to 390,000 cases of GBS infection, 91,000 neonatal deaths, more than 46,000 stillbirths, and 518,000 preterm births. Moreover, around 40,000 children who survive GBS infection show neurodevelopmental impairment.
GBS Meningitis
GBS is an opportunistic pathogen that can colonize asymptomatically the gastrointestinal and genital tracts of healthy adults, being part of the intestinal and vaginal microbiomes. The neonatal invasive infections caused by GBS can be classified into early- and late-onset disease according to the timing of symptoms’ onset and mode of transmission. The early-onset GBS disease (EOGBS) is characterized by the onset of symptoms within 7 days after birth and vertical intrapartum transmission due to aspiration of contaminated amniotic or vaginal secretions during labor. The late-onset GBS disease (LOGBS), in turn, is characterized by the beginning of symptoms between 7 and 90 days after birth and horizontal postpartum transmission (hospital environment, the mother or other caregivers, or breastfeeding). Additionally, GBS can ascend from the lower genital tract into the uterus during pregnancy and infect the fetus, causing stillbirths, preterm birth, and miscarriage (prenatal-onset GBS disease). EOGBS and LOGBS differ in their clinical manifestations. Usually, EOD is associated with sepsis and pneumonia and less frequently with meningitis, while LOGBS commonly presents with sepsis and meningitis. Although viruses are the causative agents of most cases of neonatal meningitis, GBS accounts for the highest mortality rates. In 2019, GBS accounted for the highest burden of neonatal deaths due to meningitis (22.8%), followed by Klebsiella pneumoniae (17.1%) and viruses (15.3%). Most of this burden is in low- and middle-income countries, especially in Africa and Asia. GBS can also cause meningitis in adults with underlying conditions (e.g., diabetes, heart disease, cancer, immunocompromising conditions), although the frequency of GBS meningitis in that group is lower. The GBS population is composed of several lineages, but one in specific, the hypervirulent clone CC17 associated with serotype III, is recognized as the major clone causing LOGBS and meningitis. Currently, universal GBS screening of pregnant women in late pregnancy (36-37 weeks of pregnancy) and intrapartum antibiotic prophylaxis (IAP) are recommended to prevent GBS disease. The screening involves taking swab samples from the vagina and rectum, and the pregnant women who test positive for GBS should receive antibiotics during labor (IAP). Penicillin is the drug of choice for IAP, and cefazolin, clindamycin, and vancomycin are options for women with penicillin allergies. However, IAP is effective only to prevent EOGBS but does not prevent the occurrence of LOGBS and prenatal-onset GBS disease. A maternal vaccine is considered the most promising approach to prevent all forms of disease caused by GBS, including meningitis.
Antimicrobial Resistance and GBS
Antimicrobial resistance is a topic of concern for GBS. Penicillin is the drug of choice to treat GBS infections, but penicillin-resistant strains were already detected in Japan, Europe, Canada, and the USA. Clindamycin and erythromycin are recommended to treat patients allergic to penicillin. However, the circulation of GBS strains resistant to clindamycin and erythromycin is a reality, with rates reaching nearly 50% in some regions. Considering this scenario, penicillin-resistant GBS, clindamycin-resistant GBS, and erythromycin-resistant GBS are included in the lists of pathogens that pose a threat to the public health published by the Centers for Disease Control and Prevention (CDC) and the WHO and are targets for the actions taken to tackle antimicrobial resistance.
GBS Can Be Considered a Zoonotic Pathogen?
A foodborne outbreak of invasive disease caused by GBS was reported for the first time in Singapore in 2015. The outbreak was caused by the consumption of farmed freshwater fish contaminated with GBS and affected non-pregnant and younger adults. Septic arthritis and meningitis were the predominant clinical manifestations (146 cases and 5 deaths), and the outbreak was caused by the GBS clone ST283 serotype III. GBS ST283 is a widespread clone in Southeast Asia, but it was already detected in other geographic regions, like Brazil. It causes an infectious disease in fish called streptococcosis and economic losses in aquaculture. This episode highlights the zoonotic role of GBS and its public health importance beyond the neonatal infectious diseases.
The Path Towards a Maternal GBS Vaccine
The WHO, together with many partners, defined a global strategy to tackle bacterial meningitis globally, but especially in LMICs. The global roadmap Defeating Meningitis by 2030 has the vision "Towards a world free of meningitis" and aims to tackle the main causes of bacterial meningitis worldwide. Regarding GBS meningitis, the road map fosters the development of an effective and affordable maternal vaccine, implementation of GBS surveillance strategies, and effective, accessible diagnosis and treatment. In addition, the WHO also published the document “Group B Streptococcus vaccine: full value of vaccine assessment", which describes the global public health rationale for developing GBS vaccines for maternal immunization and informs decision makers and stakeholders. Currently, the vaccine proposals in development are based on two approaches: a multivalent capsular polysaccharide (CPS)-protein conjugate vaccine and protein subunit vaccines. The CPS-based vaccine proposals cover between three and six capsular types, targeting the serotypes most associated with disease. The protein subunit proposals target proteins conserved across all GBS serotypes. A maternal GBS vaccine has not been licensed yet, but there are promising approaches in clinical trials, and it is expected that at least one GBS vaccine will be licensed for maternal immunization very soon.
International GBS Awareness Month
July is recognized as the International GBS Awareness Month, and this is a month dedicated to raising awareness about GBS disease, including GBS neonatal meningitis, among the lay public. The campaign aims to provide information and educate healthcare professionals, the public, parents, and decision-makers about GBS and the risks this pathogen can pose to the health of neonates and their mothers. Usually, nonprofit organizations like Group B Strep International (https://www.groupbstrepinternational.org/) and Group B Strep Support (https://gbsaw.gbss.org.uk/) take the lead in the campaign, but everyone can be involved and make a difference to prevent and tackle GBS meningitis!

Ever wondered if it matters which arm you get your vaccine booster in? Turns out, it just might!
New research suggests that getting your booster shot in the same arm as your first jab could help your immune system gear up faster and stronger. This simple trick could speed up protection, especially during outbreaks of fast-changing viruses like COVID-19.
Why does the arm matter?
When you get a vaccine, immune cells take the viral or bacterial antigens to the closest lymph nodes - those little immune command centers near the injection site. There, memory B cells hang out, ready to spring into action if they see the pathogen again.
The research discovered that certain immune cells such as macrophages get “primed” after the first shot and help rally the memory B cells when a booster arrives - but only if it’s in the same place (1).
In a human trial, 30 volunteers got the Pfizer COVID-19 vaccine booster—20 in the same arm, and 10 in the opposite arm (2). Guess what? Those who stuck to the same arm produced protective antibodies faster - within just one week after the booster!
Faster antibodies = faster protection
The antibodies from the “same-arm” group were not only quicker but also better at tackling variants like Delta and Omicron. While the difference faded by week four, that early immune boost could be a game changer during outbreaks.
What’s next?
If scientists can harness this local immune magic, future vaccines might need fewer boosters—saving time, doses, and hassle.
So next time you get a jab, remember: The same arm might just be your immune system’s favourite sidekick!

July 6, recognised as World Zoonoses Day, commemorates the historic achievement of Louis Pasteur, who administered the first successful rabies vaccine in 1885. While this milestone marks a triumph in medical science, the real significance of zoonotic diseases reaches far beyond. Zoonoses—diseases transmitted between animals and humans—are not isolated events. They are shaped by the way we interact with animals, ecosystems, and each other. This day invites us not only to reflect on past victories but also to examine the deeper drivers, consequences, and inequities associated with the emergence of zoonotic diseases.
What Makes a Disease Zoonotic?
A zoonosis is any infectious disease that can be naturally transmitted between vertebrate animals and humans, caused by a wide range of pathogens: viruses (e.g., SARS-CoV-2, Ebola, CCHF, Avian Influenza), bacteria (e.g., Salmonella enterica, Brucella spp., Bacillus anthracis), parasites (Toxoplasma spp., Trichinella spp.), fungi (Cryptococcus neoformans, Aspergillus spp.), and even prions (Bovine Spongiform Encephalopathy (BSE) also known as mad cow disease). Some zoonoses, like rabies or anthrax, are well-known and deadly. Others, like Hepatitis E, are underestimated but globally widespread. According to the WHO, over 60% of known human pathogens are zoonotic, and 75% of emerging infectious diseases have an animal origin. HIV itself was once zoonotic—before adapting to human-to-human transmission.
Transmission Routes and Everyday Risks
Zoonotic pathogens reach humans through various channels:
- Direct contact with animal secretions, blood, or excreta
- Indirect contact with contaminated surfaces (e.g., barns, soil, cages)
- Vector-borne transmission via mosquitoes, ticks, or fleas
- Foodborne infections via undercooked meat, raw dairy, or unwashed produce
- Waterborne transmission from contaminated water supplies
Even domestic animals can serve as silent reservoirs for zoonotic pathogens. Companion animals such as cats and dogs have been linked to the transmission of Toxoplasma gondii, Giardia lamblia, and Bartonella henselae. On a broader scale, wildlife markets, hunting practices, bushmeat consumption, and the exotic animal trade—especially involving primates, rodents, or bats—create high-risk interfaces for zoonotic spillovers.
Environmental Disruption and the Rise of Spillovers
Spillover—when a pathogen jumps from an animal host to a human—is not a rare anomaly, but a predictable outcome of ecological disruption. Zoonoses are not random accidents; they are symptoms of a planet under pressure. Deforestation, climate change, industrial livestock farming, and the wildlife trade are major contributors. A 2020 UNEP report linked increased zoonotic pandemics to the anthropogenic (human-caused) destruction of ecosystems and the rise in global meat demand. Encroachment into wild habitats and reduced biodiversity create new interfaces for disease transmission, especially in tropical regions where species are forced to coexist unnaturally due to ecological stress.
The problem is escalating: spillover events have tripled since the 1980s, and up to 850,000 unknown viruses in birds and mammals could theoretically infect humans. These risks are no longer hypothetical—they are ecological feedback loops, exposing deep flaws in global food systems, land use policies, and trade patterns.
Beyond Biology: Inequities and Invisible Burdens
Zoonotic diseases disproportionately affect low- and middle-income countries, where veterinary services, diagnostics, and outbreak surveillance are limited. Within societies, smallholder farmers, migrant labourers, and women in caregiving and food roles are more exposed but underprotected. While many zoonoses originate in animal reservoirs, the social determinants of exposure, vulnerability, and care are profoundly unequal.
Veterinarians and frontline public health workers are at high occupational risk, especially in contexts with limited PPE or training. Yet their knowledge and lived experiences are often marginalised in global health policy. Tackling zoonoses means elevating local expertise, community perspectives, and culturally embedded practices—not just imposing biomedical models from above.
Zoonoses and Antimicrobial Resistance (AMR): A Dangerous Intersection
Industrial livestock farming doesn’t just drive zoonoses—it fuels antimicrobial resistance (AMR). The prophylactic use of antibiotics in animals leads to resistant pathogens that enter the human population through food, water, or direct contact. Without strict regulation, improved biosecurity, and universal access to diagnostics, the dual threat of zoonoses and AMR will only intensify. These are not separate crises—they are intersecting syndemics, demanding integrated solutions.
One Health: From Framework to Global Action
The One Health concept acknowledges that human, animal, and environmental health are inseparably linked. But turning this into action requires more than inter-ministerial coordination. It demands:
- Joint surveillance systems across sectors
- Genomic technologies to detect early spillovers
- Cross-border data sharing and transparency
- Community-led education and behaviour change
- Reforms to global trade, agriculture, and wildlife governance
And most importantly, it requires rethinking development itself—shifting from extraction to regeneration, from inequality to inclusion, from crisis response to resilience building.
Final Thought: Zoonoses Are Warnings
On World Zoonoses Day 2025, we must see zoonotic diseases not merely as biological phenomena but as biopolitical signals—indicators of unsustainable systems, eroded habitats, and neglected communities. These diseases are not emerging from nature’s cruelty, but from our failure to coexist with nature responsibly. They reveal how extractive economies, deforestation, industrial farming, and global inequality converge to create environments where pathogens can leap from animals to humans with alarming ease.
Each outbreak is more than a health crisis; it is an ecological message—urgent and unheeded. With every spillover, the Earth warns us. These warnings are not random, nor are they isolated. They are part of a pattern driven by our collective actions and inactions. The question is not only how we can prevent the next pandemic, but whether we are willing to confront and transform the systems that continue to generate them. Without shifting the underlying drivers—be it land use, wildlife exploitation, or global trade—we will remain vulnerable.
The deeper we look into zoonoses, the clearer it becomes: our health depends on the health of all living things. Protecting biodiversity, strengthening equitable health systems, and promoting One Health principles are not optional—they are essential pillars of global survival. On this day, let us recommit not only to science but also to justice, sustainability, and a renewed sense of shared responsibility with the living world.

Introduction
Scientific breakthroughs in pathogen genomics can transform public health responses—if policymakers understand and act on them. The COVID-19 pandemic demonstrated this potential on an unprecedented scale. More than 16.8 million SARS-CoV-2 genome sequences have been submitted to GISAID—far exceeding the total submissions for all pathogens combined from 2000 to 2019 in both GISAID and NCBI. The genomics expertise and facilities developed during the pandemic are now being leveraged for the surveillance of other pathogens, strengthening public health preparedness. The key challenge now is: how can we effectively translate such complex data into compelling evidence that drives policy decisions?
Having briefed national policymakers in Pakistan during critical outbreaks, including COVID-19 and Mpox, I have learned that the impact of genomic surveillance depends not just on data generation but also on how well it is communicated. This article explores key strategies to bridge the gap between genomics and decision-making, ensuring that scientific evidence informs timely and effective public health interventions.
Know Your Audience
One of the biggest mistakes scientists make when communicating genomic data is neglecting their audience. Policymakers, often from non-technical backgrounds, may struggle to grasp the complexities of pathogen genomics. Early in the COVID-19 pandemic, I made this mistake while briefing Pakistan’s National Command and Operation Center (NCOC), where key decision-makers included a planning minister and a military general—both unfamiliar with genomic data. Even the Special Assistant to the Prime Minister on Health, an infectious disease expert, found genomics to be uncharted territory. My key takeaway? Always tailor your message to your audience. Before presenting, take time to understand their background—whether they are non-specialists or technical experts with decision-making authority. This simple step can make your insights far more impactful.
Avoid Jargon and Simplify Complex Information
Another common mistake scientists make is using excessive jargon—technical terms that can confuse non-experts. In pathogen genomics, a simple example is replacing the word mutation with change to make the concept more accessible. I learned this lesson when, during an NCOC briefing, a member interrupted me and asked me to simplify my message. I had been using SARS-CoV-2 lineage names (such as B.1.1.7 instead of Alpha variant), which meant little to my audience. Once I switched to commonly recognized names like Alpha, Beta, and Omicron, the discussion became far more engaging. Pathogen genomics offers powerful insights, but if the message isn’t clear, it risks being misunderstood—or worse, ignored. Clarity and simplicity don’t dilute science; they make it actionable.
Connect Data to Policy Actions
To maximize the impact of genomic surveillance, scientists must clearly link genomic findings to policy decisions such as travel restrictions, vaccine rollouts, and public health messaging. An example from Pakistan underscores this point. In February 2021, COVID-19 case numbers were declining after the second wave. However, our genomic data at the National Institute of Health (NIH) showed that the Alpha variant (then known as the UK variant) was increasing exponentially. We reported this trend to the NCOC in a timely manner. The result? Almost one and a half months later, the third wave began, driven by the Alpha variant. Sharing our genomic data early gave policymakers time to prepare for a possible new wave of infections.
This experience was a turning point, as it demonstrated to policymakers the importance of genomic surveillance. At NIH, we successfully used SARS-CoV-2 genomic surveillance data to detect the emergence and spread of the Delta variant before the fourth wave and Omicron and its subvariants before the fifth and sixth waves. By consistently providing timely genomic insights, we strengthened national preparedness and response efforts, ensuring that scientific evidence informed public health decisions.
Be Clear and Confident in Your Recommendations
Policymakers need clear, actionable insights—not uncertainty. Most of the time, they seek straightforward solutions—a yes or no response to critical questions. Using confident language helps instill trust in scientific findings. Instead of saying "The data suggests...," use "The data shows..." when evidence is strong.
I saw the importance of clear communication when the World Health Organization (WHO) declared Mpox a Public Health Emergency of International Concern (PHEIC) in July 2022. The declaration caused significant anxiety among health authorities in Pakistan. Misinformation and fear led to unnecessary measures, such as screening passengers at airports and collecting respiratory swabs—neither of which were appropriate for Mpox (lesion swabs are recommended). Our virology department at NIH received an influx of improper samples, leading to wasted resources and confusion.
Recognizing this issue, I provided a concise briefing to clarify key differences between Mpox and SARS-CoV-2. I explained that unlike SARS-CoV-2, which spreads primarily through respiratory transmission, Mpox is mainly transmitted through direct contact with infected individuals. I also emphasized the genetic distinction between the two viruses—Mpox, being a DNA virus, mutates far less frequently than the RNA-based SARS-CoV-2. Moreover, I provided clear guidance on patient selection, emphasizing the need to test only those with characteristic skin lesions rather than asymptomatic individuals. I also outlined proper sample collection techniques, highlighting that lesion swabs—not respiratory samples—are essential for accurate diagnosis. Additionally, I explained the recommended laboratory diagnostic methods, including real-time PCR for detecting Mpox virus DNA, ensuring that health authorities understood the best approach for reliable case confirmation. This short yet targeted intervention had a significant impact. It not only alleviated fear but also corrected the response strategy, ensuring that valuable resources were directed toward appropriate diagnostic and containment measures.
Use Visuals to Enhance Understanding
Policymakers process visual information much faster than raw data, making clear and intuitive visuals essential for effective communication. Instead of overwhelming them with intricate genetic details, use simplified figures, graphs, and infographics that highlight key findings in a clear and actionable way.
I experienced this firsthand while briefing Pakistan’s National Command and Operation Center (NCOC) during the COVID-19 pandemic. I initially presented a figure showcasing specific mutations detected through PCR to identify the Alpha variant. However, the technical nature of the figure—featuring genetic targets and mutation sites—proved challenging for non-scientific decision-makers to interpret. Midway through my presentation, the NCOC chairman interrupted and said, "This is too technical—just tell us what it means for our response."
Recognizing this, I later adopted a more visual approach, presenting a straightforward trendline that showed the Alpha variant's rise over time and its correlation with case surges. This shift in presentation made the data immediately understandable, allowing policymakers to grasp the significance of genomic surveillance in real time.
The lesson? A well-designed visual does more than simplify complexity—it transforms genomic insights into clear, actionable intelligence, ensuring that scientific evidence effectively informs public health responses.
Conclusion
Effectively communicating pathogen genomics to policymakers is essential for ensuring that genomic surveillance translates into meaningful public health actions. By tailoring messages to the audience, simplifying technical language, using confident and actionable recommendations, and leveraging clear visuals, scientists can bridge the gap between genomic data and policy decisions. The ultimate goal is to make genomics a cornerstone of public health strategy, ensuring that scientific advancements lead to timely interventions that save lives.

Every year on May 18, I take a moment not just to reflect—but to reignite a shared belief that a world free of HIV is within reach. World AIDS Vaccine Day, also known as HIV Vaccine Awareness Day, is more than a date on the calendar—it’s a global reminder of how far we’ve come, how much remains to be done, and how essential our collective commitment is. As an epidemiologist and public health advocate, I remain deeply committed to equity, innovation, and community empowerment. And today, with renewed conviction, I can say: we’re closer than ever to achieving the impossible—but the journey continues.
Why May 18 Still Matters
World AIDS Vaccine Day was inspired by a powerful call to action delivered by President Bill Clinton in 1997, urging the world to dedicate resources and energy toward developing a preventive HIV vaccine. Since then, this day has evolved into a symbol of hope and determination—for scientists, health workers, clinical trial participants, and advocates like myself. It’s not just a day of remembrance. It’s a day of action.
The Global HIV Landscape: Progress and Persistent Gaps
HIV continues to be a major public health challenge. Sub-Saharan Africa carries the greatest
burden—with countries like:
- Eswatini (27.5%)
- Lesotho (20.5%)
- Botswana (19.7%)
These rates reflect the urgent need for continued innovation and intervention. In South Africa, over 7.7 million people are living with HIV—making it the highest number globally. By contrast, countries like Cuba (0.07%) and Timor-Leste (under 0.2%) have achieved exceptionally low prevalence thanks to robust public health policies and education campaigns.
As of the end of 2023, an estimated 39.9 million people were living with HIV worldwide. While antiretroviral therapy (ART) has revolutionized treatment, turning HIV into a manageable condition, disparities remain:
- High Burden: Sub-Saharan Africa – ~3.4% prevalence among adults 15–49
- Low Burden: Middle East and North Africa – mostly under 0.1%
- Lives Lost: Over 630,000 AIDS-related deaths reported in 2023
Breakthroughs in HIV Vaccine Research: Hope on the Horizon
- There is reason for optimism. Scientific advances have brought new hope to the field:
- mRNA Vaccines: Building on COVID-19 success, mRNA platforms (e.g., Moderna) are now being tested for HIV—offering precision and adaptability.
- Broadly Neutralizing Antibodies (bNAbs): These powerful antibodies target multiple HIV strains and are being studied for prevention and treatment.
- Mosaic Vaccines: Designed to tackle HIV’s global diversity, these vaccines stimulate broader immune responses.
- VRC01 and AMP Trials: Though they didn’t produce a standalone vaccine, these trials gave us valuable data on antibody behavior and immune response.
Each step forward builds on years of effort—this is science in motion, not standing still.
But Let’s Be Honest—Challenges Remain
Despite progress, we’re still facing major hurdles:
- HIV’s Complexity: It mutates rapidly and exists in many strains—making vaccine design incredibly difficult.
- Funding Shortfalls: HIV doesn’t always command the same urgency or investment as newer pandemics like COVID-19.
- Stigma & Misinformation: Myths, fear, and marginalization hinder vaccine trust—especially in underserved communities.
- Access & Equity: Once a vaccine exists, will the people who need it most be the first to receive it? That depends on global cooperation and local engagement.
This Is Bigger Than Health—It’s a Justice Issue
Developing and delivering an HIV vaccine supports more than medical outcomes—it aligns with global development and human rights:
- SDG 3 – Good Health and Well-being
- SDG 10 – Reduced Inequalities
- SDG 17 – Partnerships for the Goals
Ending HIV is not only about medicine—it’s about addressing poverty, gender inequality, education gaps, and systemic injustice.
What Can We Do—Together?
- Champion Science: Support trusted institutions like AVAC, IAVI, and NIAID. Stay informed, and if you’re eligible and safe to do so—consider participating in trials.
- Build Vaccine Literacy: Talk about vaccines. Explain how they work. Tackle misinformation, especially in communities with limited access to accurate health information.
- Push for People-Centered Policies: Let’s advocate for frameworks that prioritize vulnerable populations and include them in planning and decision-making.
- Empower Young Leaders: Youth aren’t just future change-makers—they’re already leading. Let’s support school programs, youth-led campaigns, and digital literacy.
- Celebrate the Unsung Heroes: From lab researchers to community mobilizers to trial volunteers—these individuals are the heartbeat of progress. Let’s uplift them.
A Vaccine of Hope, A World of Possibility
World AIDS Vaccine Day is a powerful reminder of what can happen when science, solidarity, and humanity come together. As someone who has worked across HIV, TB, and socio-economic health systems, I believe in the dream of an HIV vaccine—not as a fantasy, but as a future we are building together. Let’s stay committed. Let’s stay informed. Let’s keep going with courage, compassion, and determination.

The Global Gut Crisis: Severe diarrhea and dysentery remain the leading causes of death among children under five, particularly in low- and middle-income settings. Beyond the immediate danger, diarrhea leads to malnutrition, adversely affecting physical and cognitive development, thereby perpetuating the cycle of poverty.
Rotavirus - A Major Culprit: The discovery of rotavirus in 1973 filled a significant diagnostic gap in childhood diarrhea, revealing it as the cause of 40–50% of severe acute diarrhea cases in young children worldwide (1). It most commonly affects those between 6 and 24 months old, with nearly every child experiencing at least one infection by the age of five (2). In 2016 alone, rotavirus was responsible for an estimated 128,500 deaths and over 258 million episodes of diarrhea in children under five, with 90% of global diarrheal deaths occurring in sub-Saharan Africa (3).
A Shot at Prevention - The Global Rollout of Rotavirus Vaccines
The introduction of rotavirus vaccines has been a significant milestone in reducing diarrheal morbidity and mortality. As of now, 123 countries have incorporated the rotavirus vaccine into their national immunization programs, leading to a global reduction of approximately 40% diarrheal admissions among children (4).
Challenges with oral rotavirus vaccines: Despite the progress in rotavirus vaccination, several challenges hinder its widespread impact. By the end of 2023, rotavirus vaccines had achieved approximately 55% global coverage, yet nearly 40% of countries in sub-Saharan Africa had not adopted the vaccine, highlighting significant regional disparities in access (5). These vaccines have shown higher efficacy in high-income countries, while their impact in low-income nations, where the disease burden is greatest, is still substantial. Passive transfer of maternal rotavirus antibodies, co-administration with oral polio vaccine, malnutrition, environmental enteropathy, and HIV are major factors compromising rotavirus vaccine efficacy in low-income settings (6,7).
Ongoing efforts to Tackle Diarrheal Diseases: To improve the efficacy of oral rotavirus vaccines, ongoing research is exploring alternate dosing schedules, such as neonatal administration and booster doses, as well as micro supplementation with zinc and probiotics (7). Injectable rotavirus vaccines also hold promise, as they may overcome the challenges associated with the lower effectiveness of oral vaccines in low-income settings. Combination vaccines targeting multiple pathogens, such as rotavirus and norovirus, are also in the pipeline, aiming to provide broader protection. These innovations, alongside improved water, sanitation, and hygiene (WASH) programs, offer hope for significantly lowering the global burden of diarrheal diseases, particularly in low-resource settings where they remain a major threat to child health.
With each vaccine dose, we move closer to a future where no child suffers or loses their life to preventable diarrheal diseases.

Each year on May 5, World Hand Hygiene Day is observed globally. It is spearheaded by the World Health Organization (WHO) to highlight the vital importance of hand hygiene in preventing infections and strengthening infection prevention and control (IPC) practices.
The WHO Framework for Action 2024-2030 emphasizes the importance of universal access to safe WASH and effective waste management as essential components of quality healthcare. It calls for integrating WASH and waste considerations into all aspects of health system planning, implementation, financing, and monitoring areas that can be strengthened through infection prevention and control (IPC) initiatives.
The theme for this year, "It might be gloves. It’s always hand hygiene,” underscores the fundamental importance of hand hygiene as a key measure in protecting health, especially within healthcare environments, regardless of glove use. Hand hygiene is a crucial pillar of SDG 3—ensuring good health and well-being for all.
By promoting universal access to clean water and sanitation (SDG 6), we protect communities from infections and strengthen global health resilience.
The Science Behind Hand Hygiene
Hands are the most common vector for pathogen transmission. Numerous studies confirm that hand hygiene is the single most effective practice to reduce the spread of infections, including healthcare-associated infections (HAIs), which affect millions of patients annually and contribute to antimicrobial resistance (AMR).
Key scientific facts:
- According to estimates by the Centers for Disease Control and Prevention (CDC), approximately 80% of common infectious illnesses are spread through hand contact.
- Proper hand hygiene can reduce diarrheal diseases by up to 40% and respiratory infections by 21% in the general population. (CDC)
- Effective hand hygiene disrupts the transmission of bacteria (e.g., MRSA, E. coli), viruses (e.g., influenza, norovirus, SARS-CoV-2), and fungal pathogens.
Global Situation and Gaps
Despite its proven efficacy, hand hygiene compliance remains low, especially in low- and middle-income countries (LMICs):
- Less than 40% of healthcare workers in LMICs adhere to recommended hand hygiene practices.
- More than one-third of healthcare facilities worldwide do not have sufficient handwashing stations available at the point of care.
- Many public and private healthcare facilities lack adequate water, sanitation, and hygiene (WASH) infrastructure.
- IPC breakdowns
These gaps not only compromise patient safety but also facilitate the spread of emerging and re-emerging infectious diseases, such as COVID-19, Mpox, and multidrug-resistant pathogens.
It takes just 5 moments to change the world. Clean your hands, stop the spread of drug-resistant germs! To standardize and enhance compliance, WHO introduced the “5 Moments” approach, targeting:
- Before touching a patient
- Before clean/aseptic procedures
- After body fluid exposure/risk
- After touching a patient
- After touching the patient’s surroundings
This framework provides a science-based, context-sensitive guide to minimize infection risk at critical points during care delivery.
Innovation and Behavioral Change
Recent advancements in promoting hand hygiene practiced in the COVID-19 pandemic globally include:
- Alcohol-based hand Rub (60%) formulations are recommended by WHO.
- Sensor-based hand hygiene monitoring systems in hospitals.
- Behavioral change prompts and Communication material, such as visual cues and leadership modeling, significantly improve hand hygiene adherence.
AI & Generation Hand Hygiene Innovations
With AI adoption across the world, the healthcare industry has accelerated, through the introduction of exciting scientific Innovations that guide how we approach hand hygiene in the healthcare system:
- AI-Powered Hygiene Monitoring smart sensors- which improves compliance and infection control with real-time feedback
- Advanced AI-driven sensor technology transforming healthcare environments.
- Sustainable, Waterless Hygiene Solutions
- With global water scarcity rising, waterless hand hygiene innovations—like biodegradable alcohol- based formulations and antimicrobial dry hand wipes
- UV-Based Hand Disinfection machines which kills bacteria and viruses
- Smart Dispensers & Internet of Things (IoT) Hygiene Compliance accessories which track sanitization rates amongst health care personnel.
A Perspective from Pakistan
In countries like Pakistan, efforts have accelerated post-COVID-19. However, challenges persist:
- Still, health facilities lack continuous access to hand hygiene stations.
- The national IPC project is launched covering 100 private hospitals.
- Integration of hand hygiene into infection prevention and control (IPC) policies is ongoing but needs stronger enforcement and surveillance.
The Way Forward
- Policy Strengthening: National IPC guidelines should prioritize hand hygiene as a mandatory performance indicator.
- Infrastructure Investment: Ensuring continuous availability of ABHR, soap, and water at all healthcare and public facilities.
- Capacity Building: Regular IPC training and refresher courses for healthcare workers.
- Community Engagement: Public campaigns, especially in areas with maximum exposure like schools, malls, and transport hubs, to instill lifelong hand hygiene habits.
- Monitoring and Evaluation: Establish hand hygiene auditing systems at national and sub-national levels with clear benchmarks.
World Hand Hygiene Day goes beyond symbolic recognition. It serves as a call to implement evidence-based action. Clean hands save lives, reduce disease burden, and protect healthcare systems. In a world facing increasing biosecurity threats, hand hygiene remains our first line of defense. *Let’s commit together to clean care for all*

India’s Universal Immunization Programme (UIP), the world’s largest vaccination initiative, vaccinates over 2.9 crore pregnant women and 2.6 crore newborns annually against 12 vaccine-preventable diseases (VPDs), including measles and rubella. This effort has significantly reduced child mortality, with under-5 mortality rates dropping from 45 to 32 per 1,000 live births between 2014 and 2020 1.
The launch of the National Zero Measles-Rubella (MR) Elimination Campaign 2025-26 during World Immunization Week is a pivotal moment in India’s public health journey 2. The campaign targets 100% immunization coverage by administering two doses of the MR vaccine to every child, ensuring no child is left behind and promoting both individual and community health.
Milestones to Celebrate: Significant Progress So Far
By early 2025, 332 districts reported zero Measles cases and 487 districts reported zero Rubella cases between January and March, highlighting the success of vaccination efforts and progress toward elimination 2.
Powerful Tools Driving Success: Key Government Initiatives 1
- Mission Indradhanush (2014): Targets children missed by the UIP with focused vaccination drives in low-coverage areas.
- Intensified Mission Indradhanush (IMI): Accelerates vaccination in high-priority districts and urban slums with mobile vans and real-time monitoring.
- eVIN (Electronic Vaccine Intelligence Network) : Tracks vaccine stocks and prevents wastage, ensuring safe storage and delivery.
The Roadmap to Eliminate Measles and Rubella: India’s Strategic Plan
India’s MR elimination strategy includes:
- Immunization Coverage: Achieving 95% vaccine coverage in every district. As of the 2024-25 Health Management Information System (HMIS) data, the country has achieved a 93.7% coverage for the first dose and 92.2% for the second dose2. This marks a significant achievement but also highlights the remaining gaps to achieve complete coverage.
- Enhanced Surveillance: A robust surveillance system is essential for detecting any outbreaks early and responding quickly. India’s efforts to strengthen surveillance mechanisms will ensure that no case goes undetected, facilitating a swift public health response when necessary
- Outbreak Preparedness: Preparing for potential outbreaks is another key strategy. India’s experience with Polio and Maternal and Neonatal Tetanus elimination provides valuable insights into how coordinated efforts and quick responses can prevent widespread outbreaks and protect vulnerable populations.
- Demand Generation: Addressing vaccine hesitancy remains a critical challenge. India is conducting focused mass awareness campaigns to dispel myths, provide accurate information about the MR vaccine, and build community trust.
- Inclusive Participation: The success of the MR elimination campaign relies on the collective efforts of all stakeholders, from health professionals and local government officials to community leaders and frontline workers. By working with local authorities and engaging in community-based awareness programs, India is ensuring that vaccination efforts reach even the most marginalized populations.
India’s comprehensive approach to Measles and Rubella elimination sets a strong foundation for achieving complete eradication by 2026, ensuring a healthier future for its children.
