Now, the challenges lie in the Middle East. In Iraq and Syria, violence and the dislocation of refugees make it hard for vaccination campaigns to stay strong and reach all the kids they need to. Earlier this week, international officials confirmed Iraq has one case of polio, its first in 14 years, IRIN reports. Syria is also sustaining a polio outbreak, as the war there has stalled vaccination efforts. Before the war, 99 percent of Syrian kids were vaccinated against polio, NBC News reports. In 2012, only 52 percent of eligible children got the vaccine. Officials are especially worried that Syrian refugees will bring more polio into Iraq.
