In this Wednesday, May 30, 2012 photo, a boy and his mother peek through a window decorated with a banner urging people to take polio vaccinations outside a children's hospital in Peshawar, Pakistan. In February 2012, the world was cheered to learn that India had gone a full year with no new cases of polio - a landmark that left only Pakistan, Afghanistan and Nigeria on the World Health Organization's list of countries where the disease is endemic. But the battle is far from over, judging by the WHO's latest expressions of alarm. It says that in both Nigeria and Afghanistan the number is creeping up, while budget shortfalls are jeopardizing the effort to hold polio at bay in 24 other high-risk countries.
