October 27, 2013 Just a few decades ago, polio was crippling more than a thousand children each day. Now the paralyzing virus remains endemic to only three countries. A timeline shows how polio went from one of the most feared illnesses to a disease on the ropes.
October 21, 2013 Syria used to have one of the highest rates of polio vaccinations in the region. But since the civil war began, rates have plummeted. Now the crippling virus has likely returned to the country, health officials say. Initial tests indicate that polio has paralyzed at least two children.
October 8, 2013 Bombs targeting polio vaccinators have threatened the global effort to stamp out the disease once and for all. The attacks are likely to continue, researchers warned, unless there's a change in eradication strategy toward local action.
July 31, 2013 In the 1970s, Ali Maow Maalin, a Somali hospital worker, was the last member of the general public to catch smallpox — worldwide. Once recovered, he worked for years to wipe out polio in Somalia. Maalin, called "an inspiration" by world health leaders, died unexpectedly last week.
June 28, 2013 The world is closer than ever to wiping out polio. But a growing outbreak in the Horn of Africa has health workers worried that the virus could spread to surrounding regions. Thirty-one kids have been paralyzed by the poliovirus in the past two months, and the number is expected to rise.
May 22, 2013 A handful of polio infections in Kenya and Somalia could set back efforts to wipe out the virus worldwide, health workers warned Wednesday. The last time there was polio in this region, the virus spread throughout the Horn of Africa into the Middle East and eventually into Indonesia.
May 8, 2013 The Microsoft founder and philanthropist is putting his money and time where his passion is: eradicating polio. Gates talks with NPR's Robert Siegel about why it makes sense to spend an estimated $5.5 billion to wipe out the disease once and for all.
February 12, 2013 The world is close to wiping out polio, as the number of new cases is at an all-time low. But recent violence against polio vaccinators threatens to reverse this progress. Recently, gunmen killed nine polio vaccinators in Nigeria, mirroring attacks in Pakistan in December.
December 20, 2012 Pakistan temporarily halts the polio vaccination program after at least eight health workers are murdered while inoculating children.
December 4, 2012 The appearance of an unusual type of poliovirus in Pakistan exposed gaps in vaccination campaigns. When a community isn't well immunized against polio, the weakened virus used in the oral vaccine can mutate and then infect unvaccinated people.
November 14, 2012 Pakistan is close to eradicating one of the last two remaining types of polio left in the country, researchers announced on Monday. They haven't seen a case of this type in nearly seven months. Health workers are cautiously optimistic that their extra vaccination efforts are starting to pay off.
