Imagine a world where a crippling disease that once paralyzed and killed countless children is now virtually extinct in an entire region. That’s the reality in WHO’s South-East Asia Region, which is celebrating 15 years since the last case of wild poliovirus. But here’s where it gets even more remarkable: the lessons and innovations from the polio eradication campaign are now driving broader public health victories across the region.
Home to a quarter of the world’s population, the South-East Asia Region has not only maintained its polio-free status but has also transformed the fight against this disease into a blueprint for tackling other health challenges. As Dr. Catharina Boehme, Officer--Charge of the WHO South-East Asia Region, aptly puts it, ‘This extraordinary achievement followed unparalleled efforts and demonstrates what can be accomplished and sustained through unwavering government leadership, a dedicated health workforce, and strong partnerships, including with communities.’
Let’s rewind to 2011. An 18-month-old girl in Howrah, West Bengal, India, became the last recorded victim of wild poliovirus in the region. The swift and comprehensive response that followed ensured no new cases emerged. By 2014, the region was officially certified polio-free—a testament to the power of collective action.
But staying polio-free isn’t just about celebrating past victories; it’s about constant vigilance. The region maintains strict surveillance, collecting over 50,000 stool samples annually and testing them through a network of 13 WHO-accredited laboratories. Environmental surveillance at 93 high-risk sites across five countries adds an extra layer of detection, ensuring no potential transmission goes unnoticed.
And this is the part most people miss: the polio program’s impact extends far beyond polio itself. Member countries have leveraged its innovations and systems to strengthen routine immunization, eliminate measles and rubella, enhance laboratory capacities, and improve emergency preparedness. These efforts have expanded immunization coverage, reached previously underserved communities, and closed critical immunity gaps.
Take, for instance, the region’s success in eliminating maternal and neonatal tetanus and reducing mortality from diseases like pneumococcal disease, rotavirus, hepatitis B, Japanese encephalitis, typhoid, and human papillomavirus through vaccination campaigns.
Yet, the fight isn’t over. As long as polio exists anywhere in the world, the risk of importation remains. Countries must sustain high immunization coverage, sensitive surveillance, and rapid response capacities—not just for polio but for all vaccine-preventable diseases.
Here’s a thought-provoking question for you: Can the world truly eradicate polio, or will it always linger as a threat? Share your thoughts in the comments—we’d love to hear your perspective.
As Dr. Boehme emphasizes, ‘The journey from polio endemicity to sustained polio-free status demonstrates that ambitious public health goals are achievable.’ WHO remains committed to supporting countries in protecting every child through robust immunization systems and advancing disease elimination across the region.
This isn’t just a story of triumph over a single disease; it’s a testament to what humanity can achieve when we work together. So, let’s celebrate this milestone—but let’s also stay vigilant, because the legacy of polio eradication is still writing its next chapter.
