At least six Americans have been exposed to the Ebola virus during a deadly outbreak in the Democratic Republic of Congo, sources have told CBS News, the BBC’s US partner.
The World Health Organization (WHO) has declared the outbreak as an international emergency, with the DR Congo’s health ministry reporting around 350 suspected cases and 91 deaths.
One American is believed to have symptoms, with three others said to have faced a high-risk contact or exposure. It is unclear whether any have been infected.
The US Centers for Disease Control and Prevention (CDC) said it was supporting the “safe withdrawal of a small number of Americans who are directly affected”, but did not confirm how many.
The current strain of Ebola is caused by the Bundibugyo virus, for which there are no approved drugs or vaccines.
