Brazil monitors two patients under Ebola surveillance
In São Paulo, a 37-year-old man who returned from the Democratic Republic of Congo (DRC) presented fever, meeting case definition; he is isolated at the Emílio Ribas Infectology Institute. In Rio de Janeiro, a traveler from Uganda showed cough, chills and diarrhoea, tested positive for malaria, and remains under investigation.
Regional outbreak background
The suspected cases arise during a Bundibugyo Ebola outbreak, first identified in 2007. The WHO declared a public-health emergency of international concern on 15 May 2026. Africa CDC reports over 1,000 suspected cases in the DRC, nearly 250 deaths, and confirmed spread to Uganda.
Key numbers
WHO data list 134 confirmed Bundibugyo cases across the DRC and Uganda, with 18 deaths (?14 % fatality). The DRC ministry cites 263 confirmed cases and 906 suspected cases, of which 223 deaths occurred among the suspected. No Ebola case has been confirmed in Brazil.
Official responses
Brazil’s Ministry of Health activated the National Contingency Plan, ordering isolation, notification and lab investigation for the São Paulo patient. São Paulo’s health department stressed a technical assessment that the risk of introduction into Brazil or South America is very low. WHO Director-General Tedros urged early care-seeking and said recovery is possible with supportive treatment. Africa CDC’s Jean Kaseya warned the outbreak may be wider than reported.
Community concerns and criticism
Health workers in the DRC report community mistrust, with residents refusing assistance and attacking facilities over burial-rite restrictions. Doctors Without Borders called for faster aid and expanded testing. Recovered patient Ezo Étienne described widespread fear that early symptoms were dismissed as poisoning, underscoring need for clear communication.
Conflicting test results
The São Paulo patient later tested positive for meningitis, while the Rio de Janeiro patient tested positive for malaria; neither result confirmed nor excluded Ebola. Authorities have not identified the patient’s province of origin in the DRC, and definitive Ebola test results remain pending, leaving transmission risk uncertain.
Verbatim quotes
- “If you come to health facilities when you have symptoms, you can get the support and recover, so the key is to come forward as early as possible and get the necessary support.” — Dr. Tedros Adhanom Ghebreyesus, WHO Director-General
- “Being able to come out of this alive is an immense source of happiness.” — Ezo Étienne, recovered Ebola patient
- “That was all they could provide.” — Ezo Étienne, recovered Ebola patient
- “The technical assessment indicates that the risk of the disease being introduced into Brazil and South America remains very low.” — São Paulo State Health Department
What’s next
Laboratory results will determine whether Ebola is present in either patient. A negative outcome will close the investigations; a positive result will trigger contact tracing, continued isolation, and expanded surveillance across Brazil. WHO will maintain coordination with national authorities and humanitarian partners to reinforce testing, treatment and community engagement in affected regions.
