The Ebola outbreak in the Democratic Republic of Congo is spreading faster than efforts to fight it, the head of the World Health Organisation has warned. Nearly three months into the outbreak, new cases are doubling in some hot spots, Tedros Adhanom Ghebreyesus said in a post on X. It comes as some health workers in the DR Congo are striking over a lack of pay. The outbreak has accounted for 3,874 confirmed cases, including 1,751 deaths, according to the latest data from DR Congo’s Ministry of Health. Tedros called for action to reach all affected localities, strengthen coordination under the government’s leadership and protect health workers.
