KINSHASA, Congo (AP) — The world’s fastest-growing Ebola outbreak is spreading faster than efforts to fight it, the head of the World Health Organization said on Wednesday during a visit to Congo where some health workers are striking over a lack of pay. It was the second visit by the WHO director-general to the Central African country since the outbreak was declared in mid-May. The outbreak has accounted for 3,874 confirmed cases, including 1,751 deaths, as of Monday, according to the latest data from Congo’s Ministry of Health. Anicet Baluku, a resident of Bunia, the capital of Ituri, blamed the death of his two brothers from Ebola on the strike. Tedros called for action to reach all affected localities, strengthen coordination under the government’s leadership and protect health workers.
