Africa's top health body said Thursday that the fastest-growing Ebola outbreak on record in eastern Congo is rapidly spreading beyond its epicenter. The Africa Centres for Disease Control and Prevention said that in recent weeks new cases and deaths have declined in Ituri province, the outbreak's epicenter, but risen sharply in neighboring North Kivu and Haut-Uele. According to the latest government figures released on Thursday, 6,843 cases have been reported, including 3,310 deaths. Ituri province remains the hardest-hit province with more than 5,400 cases, while North Kivu has reported over 1,000 cases since the outbreak was declared in May. The outbreak is spreading under extremely difficult conditions, fueled by insecurity and displacement.
