Brazil's health authorities are closely monitoring two patients for potential Ebola infection in São Paulo and Rio de Janeiro. The first patient, a 37-year-old man from the Democratic Republic of the Congo, is exhibiting symptoms such as fever, while the second patient, a Belgian man who recently arrived from Uganda, shows symptoms including cough, chills, and diarrhea. Both patients are undergoing testing, with results expected next week. If either case is confirmed as Ebola, it would mark the first reported infection outside Africa during the ongoing outbreak, which has already seen over 1,000 suspected cases and 246 deaths in the Democratic Republic of the Congo. The outbreak is attributed to a rare strain of the virus known as Bundibugyo, which is particularly concerning as it lacks a proven vaccine and has a mortality rate of about one-third among those infected. Despite being diagnosed with other conditions—meningitis for the man from DR Congo and malaria for the Belgian patient—health officials stress that the possibility of Ebola infection has not been ruled out.
