Ebola outbreak in Congo: The U.S. Centers for Disease Control and Prevention confirmed Friday that a second U.S. citizen working for a humanitarian organization has tested positive for Bundibugyo virus, a strain of Ebola. U.S. and international partners are supporting contact tracing and enhanced health screenings as officials assess risk.
Ebola outbreak in Congo: what happened
The CDC said it is aware the U.S. citizen “has tested positive for Bundibugyo virus, a type of Ebola,” and described the case as linked to the ongoing outbreak in the Democratic Republic of the Congo (DRC). The individual’s employer and public health partners are coordinating with the CDC to evaluate exposure and next steps.
Congolese authorities first declared the outbreak in mid-May. Officials emphasize rapid containment measures while investigations continue into recent chains of transmission.
Case details and U.S. response
The CDC said it is working with the patient’s employing organization, other U.S. federal agencies, public health authorities, and partners in the DRC to support contact tracing and risk assessments. Officials are identifying high-risk contacts and advising monitoring and quarantine as indicated.
A brief human element: media reports cited by news outlets say a doctor who was evacuated earlier in the response later tested negative and returned to the United States; that recovered clinician spoke to reporters about gratitude for care and family reunification. Authorities have not publicly released identifying medical details for the newly confirmed U.S. patient.
Enhanced health screenings for travelers from affected areas have been put in place and some restricted entry measures for non-U.S. citizens from the region were implemented earlier in the response to reduce importation risk.
Outbreak scale and regional spread
According to the Africa Centers for Disease Control and Prevention (Africa CDC), this is the fastest-growing Ebola outbreak ever recorded in Africa: Africa CDC reports 1,830 confirmed cases and 648 deaths in the DRC. Cases have also been reported across the border in Uganda, underscoring active cross-border transmission concerns.
The World Health Organization has assessed the global risk as low but warns regional health systems remain under strain and localized spread is a serious concern. Authorities continue surveillance, laboratory confirmation, and intensified community engagement in affected provinces.
What this means for travelers and public health
Bundibugyo virus transmits through direct contact with the bodily fluids of an infected person, contaminated surfaces or materials, and during traditional burial practices where direct contact may occur. It is not known to spread by airborne transmission in routine conditions.
There is currently no approved vaccine or specific antiviral treatment for Bundibugyo virus. Public health responses rely on classic outbreak control measures: rapid case detection, isolation of patients, contact tracing, safe clinical care, and community engagement to limit spread.
Travelers to the region should follow guidance from public health authorities, expect enhanced health screening on return, and seek medical attention promptly if they develop symptoms after travel. U.S. public health officials say no additional cases have been confirmed in the U.S. beyond the two reported patients to date.
Source notes and next steps
U.S. and international partners say they will continue supporting local health systems in the DRC to trace contacts, perform risk assessments, and limit further spread. Key outbreak figures cited above — 1,830 confirmed cases and 648 deaths — are from the Africa CDC and remain subject to revision as surveillance continues.
The CDC provided the agency statement confirming the second U.S. case and outlined ongoing coordination with partners. Media coverage of earlier evacuations and a recovered clinician is cited in contemporaneous news reporting.
