Health authorities in Kinshasa declared the Ebola virus under control five weeks after the latest outbreak left 89 people dead in eastern Democratic Republic of Congo.
The health ministry announced the outbreak on August 1 in North Kivu province and on Thursday revealed that it had spread to Butembo, a city of a million people.
But Health Minister Dr Oly Ilunga Kalenga said: "Since August 13, there have been practically no more cases, we can say that the situation has been brought under control at the epicentre (of Mabalako)."
"Even at Butembo, the situation is not critical," the minister told a news conference also attended by Congolese professor and leading Ebola researcher
