GENEVA (AP) - The spread of polio in Yemen and Indonesia is adding new urgency to attempts to contain the disease in countries previously believed to be polio-free, the U.N. health agency said Wednesday.
The outbreak has grown to 63 cases in Yemen, while two more cases were confirmed in Indonesia, bringing the total there to six since May 3, the World Health Organization said.
Six million doses of vaccine are on their way to Yemen for a second round of immunizations and a vaccination campaign is under way in Indonesia, but experts expect several more polio cases to emerge before the outbreaks are contained.
