Health officials in Brazil are currently monitoring two people for possible Ebola infections. One suspected patient, a 37-year-old man from the Democratic Republic of the Congo (DR Congo), who began exhibiting symptoms such as fever, São Paulo’s state government said.

The other case is in Rio de Janeiro. These two cases are in Brazil’s two largest cities, sparking concern for the country.

The test results for both patients should become available next week. If confirmed, they would be the first cases of infection outside Africa since the outbreak began in the DR Congo, according to a BBC report. 

There are now more than 1,000 suspected Ebola cases in DR Congo, with at least 246 deaths. Uganda has reported nine confirmed cases and one death.

On Saturday, the medical charity Médecins Sans Frontières (MSF) warned that the rapid spread of the virus had caused an “alarming situation”, with an unprecedented number of cases recorded so soon into the outbreak.

This outbreak has spread rapidly without any reasonable level of containment yet. However, despite the possible cases of the virus outside Africa, the World Health Organization has repeatedly stressed that its global spread is highly unlikely.
