Health authorities in Brazil are monitoring two patients for possible Ebola infections in the country’s largest cities, São Paulo and Rio de Janeiro, amid concerns over a growing outbreak in Africa.
Officials in São Paulo reported that a 37-year-old man from Democratic Republic of the Congo developed symptoms including fever and is undergoing testing for the virus. Meanwhile, health authorities in Rio de Janeiro activated emergency safety protocols after a Belgian traveler who recently arrived from Uganda displayed symptoms such as cough, chills, and diarrhea.
Laboratory results for both patients are expected next week.
If either case is confirmed, it would mark the first Ebola infection detected outside Africa since the current outbreak began in the Democratic Republic of the Congo.
The outbreak has already resulted in more than 1,000 suspected cases in DR Congo and at least 246 deaths. Uganda has also reported nine confirmed infections and one fatality linked to the disease.
Health officials note that both patients in Brazil have already received separate diagnoses. The patient in São Paulo tested positive for meningitis and remains in serious condition, while the traveler in Rio de Janeiro was diagnosed with malaria. However, authorities stress that these findings do not eliminate the possibility of a simultaneous Ebola infection.
The current outbreak is being driven by the rare Bundibugyo strain of the Ebola virus, a variant for which there is currently no proven vaccine. Historically, the strain has carried a fatality rate of roughly one-third of infected patients.
Ebola is a viral disease that is believed to originate in animals, particularly fruit bats, before spreading to humans through contact with infected animals or their bodily fluids. Human-to-human transmission occurs through direct contact with bodily fluids such as blood, saliva, sweat, urine, vomit, semen, or feces from an infected individual.
Over the weekend, Médecins Sans Frontières (MSF) warned that the outbreak has reached an “alarming” stage, citing the unusually rapid rise in cases during the early phase of the epidemic.
At the same time, Tedros Adhanom Ghebreyesus is visiting the heavily affected Ituri province in DR Congo to oversee containment and response efforts.
Despite the suspected cases in Brazil, the World Health Organization has repeatedly emphasized that the risk of widespread global transmission remains low and that international spread of the outbreak is considered highly unlikely.
Health officials in Brazil continue to monitor both patients closely while awaiting definitive test results that will determine whether the country is facing its first Ebola cases linked to the ongoing African outbreak.
