Bundibugyo Ebola climbs to 515 confirmed cases in DRC, up from 363 four days earlier

The CDC counts 515 confirmed cases and 91 deaths in the DRC as of June 6, up from 363 on June 2, in an outbreak with no licensed vaccine or treatment.

The Bundibugyo virus outbreak in the eastern Democratic Republic of the Congo is still growing. As of June 6, the U.S. Centers for Disease Control and Prevention counts 515 confirmed cases and 91 confirmed deaths in the DRC. As of June 5, it counts another 19 confirmed cases and two deaths across the border in Uganda — a regional total of 534 cases and 93 deaths.

The trajectory is the story, and it holds on a like-for-like read. When the CDC and the DRC and Ugandan health ministries first described the outbreak in an MMWR Notes from the Field, the DRC’s confirmed count stood at 363 cases and 62 deaths as of June 2, part of a region-wide total of 378 cases and 63 deaths. Four days later, the DRC count had climbed to 515. The European Centre for Disease Prevention and Control (ECDC), working from a slightly earlier Ministry of Health update, recorded 381 DRC cases and 64 deaths as of June 3 and flagged “18 new confirmed cases and 2 new deaths” reported on a single day. The numbers are still moving in one direction.
