The World Health Organization reports progress in containing the Ebola outbreak in the eastern Democratic Republic of Congo, but says many challenges to its elimination remain. WHO reports the number of cases in the outbreak now stands at 3,207, including 2,144 deaths. The executive Director of WHO Health Emergencies, Michael Ryan, says he is largely optimistic that aid workers are getting control of the Ebola outbreak in eastern Congo. But, he says, it is impossible to say the outbreak is over. In fact, the virus has come full circle. Ryan notes the disease has moved from Butembo and other urban areas to the remote, rural town of Mangina, the epicenter of the outbreak. He says the virus is back where it began when the Ebola outbreak was declared August 1, 2018.
