The Democratic Republic of the Congo has reported more than 500 deaths from the ongoing Ebola outbreak, according to the World Health Organization. As of July 4, at least 506 people had died and 1,561 were confirmed infected. The outbreak, officially declared on May 15, is caused by the Bundibugyo strain, for which no vaccine or treatment currently exists. WHO has begun two clinical trials and authorized emergency use of a molecular diagnostic test.

The outbreak’s epicenter is believed to be Mongbwalu in Ituri province, where the fatality rate has reached 50.7 percent. Health authorities have not yet identified the first patient, and thousands of potential contacts remain untraced. The first month of this outbreak has been the deadliest on record. Neighboring Uganda has reported two deaths and 20 confirmed cases.

The situation has been further strained by a strike threat from frontline health workers in Ituri, who cite unpaid allowances, poor working conditions, and lack of supplies. The virus has also spread near North and South Kivu provinces, where conflict and limited access complicate containment efforts.
