The World Health Organization (WHO) has declared the Ebola outbreak in the Democratic Republic of Congo (DRC) a public health emergency of international concern (PHEIC). This declaration follows a rapid escalation of cases, with 10 confirmed and 336 suspected cases, alongside 88 deaths in the DRC as of May 17. Neighboring Uganda has also reported two confirmed cases and one death.
The US Centers for Disease Control and Prevention (CDC) announced new travel restrictions, including screening and monitoring for Americans arriving from the DRC, Uganda, and South Sudan. Non-US passport holders who have traveled to these countries within the past 21 days will be barred from entry.
Outbreak Details and Strain
The current outbreak is caused by the Bundibugyo strain of the Ebola virus, which is less common and lacks clinically validated treatments or vaccines. This marks only the third recorded outbreak involving this particular strain, which has historically shown fatality rates ranging from 25% to 50%. In contrast, the more common Zaire strain has developed treatments and vaccines.
The WHO cited several factors for the PHEIC declaration, including clusters of suspected cases and deaths across multiple health zones in the DRC, four deaths among healthcare workers, and a lack of clear links between geographically distant cases. These indicators suggest the outbreak is larger than currently detected and is spreading regionally. The organization also highlighted ongoing insecurity, a humanitarian crisis, high population mobility, the urban nature of the hotspot, and a large network of informal healthcare facilities as factors compounding the risk of spread.
American Citizen Infected
The US Centers for Disease Control and Prevention (CDC) announced new travel restrictions, including screening and monitoring for Americans arriving from the DRC, Uganda, and South Sudan.
Captain Satish Pillai, incident manager for the CDC’s Ebola response, confirmed that an American citizen in the DRC has been infected with the virus. The individual, identified as Dr. Peter Stafford by the Christian missionary organization Serge, developed symptoms over the weekend and tested positive on Sunday. Dr. Stafford has been working at Nyankunde Hospital in Bunia, DRC, since 2023.
The CDC is facilitating the transfer of Dr. Stafford and six other Americans to Germany for medical care. The group includes Dr. Stafford’s wife, Dr. Rebekah Stafford, their four children, and Dr. Patrick LaRochelle, also with Serge. While all three doctors had exposures, Dr. Rebekah Stafford and Dr. LaRochelle are currently asymptomatic.
