Why Dismantling India’s Polio Network Could Invite The Virus Back, Say Doctors
Introduction India’s triumph over polio was one of the country’s greatest public health achievements. In 2014, the World Health Organization (WHO) declared India polio-free, marking a historic milestone after decades of tireless vaccination drives, especially through the Pulse Polio programme. However, experts and doctors across India are raising an alarm — if the existing polio surveillance and immunization network is dismantled or underfunded, the virus could silently return. In a densely populated country like India, where infectious diseases spread easily, complacency could reverse years of hard-earned progress. This blog explains why India’s polio network must remain strong, how it helps detect and prevent outbreaks, and why the threat of reintroduction is real — not just from within the country, but from global sources. What Was India’s Polio Network? India’s polio network was built under the Global Polio Eradication Initiative (GPEI), in collaboration with WHO, UNICEF, Rotary International, and the Indian government. The network included: Pulse Polio Immunization (PPI) campaigns — door-to-door vaccination of children under five. AFP (Acute Flaccid Paralysis) surveillance — tracking any case of sudden paralysis to detect potential polio. Environmental surveillance — testing sewage samples for the poliovirus. Mass awareness drives — promoting vaccination through celebrities and community leaders. This network was more than a vaccination programme — it was a nationwide disease surveillance system, reaching every corner of India, even in hard-to-access rural or conflict-affected regions. Why Doctors Warn Against Dismantling the Network Public health specialists say that the infrastructure built for polio eradication — including labs, trained health workers, and data systems — plays a crucial role beyond polio. If dismantled, India would lose: Early detection of infectious diseases like measles, COVID-19, or Nipah. Community health data collection, vital for planning responses. Rapid outbreak response teams already trained in contact tracing. Public trust and outreach networks, especially in rural India. “Polio-free does not mean risk-free” Though wild poliovirus has been eliminated from India, it still exists in Pakistan and Afghanistan. Travelers or migration can reintroduce the virus anytime. The environmental surveillance network helps detect such silent imports before they spread. Without this system, a single unnoticed case could cause a local outbreak, especially where routine immunization rates are low. Lessons from Other Countries Several countries that reduced vaccination or surveillance efforts saw disease resurgence: Nigeria (2003–2016): Suspension of polio vaccination led to virus return. Indonesia (2005): Imported virus triggered outbreaks after a pause in campaigns. UK (2022): Poliovirus detected in London sewage after decades — a stark reminder that polio can reappear anywhere. India’s dense population, sanitation challenges, and cross-border movement make it even more vulnerable if vigilance drops.

Routine Immunization: Systems used for polio now support vaccination for measles, rubella, and diphtheria. Data and Laboratory Systems: Provide accurate information on infectious disease trends. Community Trust: Built through years of consistent outreach, especially among hesitant groups. Thus, keeping this network intact supports India’s entire public health ecosystem. What Could Happen If the Network Is Dismantled Experts outline three major risks: Virus Reintroduction: Travelers or environmental exposure could bring the poliovirus back. Missed Detection: Without sewage and AFP surveillance, early warning would be lost. Weak Immunization Coverage: Reduced outreach could increase vaccine hesitancy. If these occur, India could again face poliomyelitis cases — children suffering irreversible paralysis due to a preventable disease. The Science: Why Constant Surveillance Matters The polio virus spreads via the fecal-oral route — often through contaminated water or food. It can circulate silently for months before causing paralysis. Environmental testing detects even tiny genetic traces of the virus in sewage samples. This allows health teams to act before outbreaks happen. The virus’s ability to mutate into vaccine-derived poliovirus (VDPV) adds another layer of concern. Continued monitoring ensures that even these rare strains are detected early. Government and WHO Recommendations The Ministry of Health and Family Welfare and WHO India recommend: Maintaining the full National Polio Surveillance Project (NPSP). Integrating it with routine immunization and disease surveillance. Continued funding for laboratory networks. Training community workers for multiple disease tracking. WHO emphasizes: “As long as one child anywhere has polio, all children are at risk.” Public Awareness: The Human Factor Public participation was key to India’s success in becoming polio-free. Bollywood icons like Amitabh Bachchan’s “Do Boond Zindagi Ki” campaign helped mobilize millions. Sustaining this awareness is vital. If people start believing that polio is “gone forever,” they may skip vaccination rounds — a dangerous trend that could undo progress. Preventing a Comeback: What Needs to Be Done To prevent polio’s return: Sustain funding for surveillance and vaccination. Strengthen routine immunization through digital monitoring. Improve sanitation and hygiene to block fecal-oral transmission. Enhance border health checks for travelers from endemic nations. Promote vaccine confidence via community engagement. Public health is not just about eradication — it’s about sustained protection. When to See a Doctor If your child has: Sudden weakness in limbs Fever with paralysis Muscle pain or fatigue Seek immediate medical evaluation. Early detection of Acute Flaccid Paralysis (AFP) is key for both diagnosis and public health surveillance. Visit a general physician or paediatrician listed on Quickobook for guidance and testing. Conclusion India’s victory over polio was not just about vaccines — it was about commitment, coordination, and constant vigilance. Dismantling the surveillance network now would risk undoing decades of progress and put millions of children at risk again. Doctors across India agree: the fight against infectious diseases never truly ends. Continued investment in the polio network will ensure India stays protected — not only from polio but from future outbreaks of all infectious diseases. 50 Expert FAQs on Polio and Infectious Diseases Q1.
