The World Health Organization has declared the polio virus eradicated in India, after nearly two decades and a multi-billion-dollar effort. The country’s last case of the wild polio virus was found in a two-year-old girl in West Bengal in January 2011. Because it has been three years without any new cases, the country can be certified as polio-free. Afghanistan, Pakistan, and Nigeria are now the only countries where the virus is still endemic, primarily because of violent conflicts, weak health systems, and lack of sanitation.
