Brazil is treating its first suspected case of the Ebola virus, the country’s Health Ministry announced Thursday night.

A 47-year-old man arrived in Brazil on Sept. 19 from Guinea and reported he had a fever on Oct. 8, within the 21-day Ebola incubation limit. He has no other symptoms, like bleeding or vomiting, but has been put in isolation and flown to the National Institute for Infectious Diseases in Rio de Janeiro per the country’s security protocol.

Guinea, Liberia and Sierra Leone are the three West African countries hardest hit by the virus.

Brazil’s Health Ministry will hold a news conference on the case at 10 am on Friday.
