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 on Monday. These measures include screening and monitoring US citizens arriving from the DRC, Uganda, and South Sudan. At the same time, non-US passport holders who have traveled to these countries within the past 21 days will be barred from entry.
Outbreak Details and Response
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 a fatality rate ranging from 25% to 50%. In contrast, the more common Zaire strain has developed treatments and vaccines.
The WHO's decision to declare a PHEIC was influenced by several factors, 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 more widespread than currently detected and is spreading regionally. The WHO also cited ongoing insecurity, a humanitarian crisis, high population mobility, the urban nature of the current hotspot, and a large network of informal healthcare facilities as factors compounding the risk of spread.
American Citizen Infected
During a CDC press briefing on Monday afternoon, Captain Satish Pillai, incident manager for the CDC’s Ebola response, confirmed that an American citizen in the DRC has been infected with Ebola. The individual developed symptoms over the weekend and tested positive on Sunday. The CDC is facilitating the transfer of this individual, along with six other Americans, to Germany for medical care.
Serge, a Christian missionary organization, identified the infected American as Dr.
Peter Stafford, who has been working at Nyankunde Hospital in Bunia, DRC, since 2023. The six other Americans being relocated include his wife, Dr. Rebekah Stafford, their four children, and Dr. Patrick LaRochelle, another doctor with the organization. All three doctors had exposures to the virus, though Dr. Rebekah Stafford and Dr. LaRochelle are currently asymptomatic.
