Since the beginning of the outbreak in August, 2018, 279 cases of Ebola virus disease have been reported in the provinces of North Kivu and Ituri in DR Congo. As of Oct 30, 244 of the 279 cases have been laboratory confirmed. Of the 244 confirmed patients, 81 have recovered, 144 have died from their illness, and the remaining 19 patients are being treated in Ebola treatment centres in the region.

So far, the surveillance teams have been able to visit an average of 140 health facilities a day.
