Twenty-one people have died of yellow fever in Democratic Republic of Congo, some of them from infections contracted in neighbouring Angola, the World Health Organization said on Tuesday.
An outbreak has already killed 225 people and infected 1,600 in Angola. There was now a high risk of further spread in Congo, given the number of people who regularly travel between the two countries, the WHO said.
A WHO official on March 18 said an outbreak, which broke out late last year, had killed 158 people in Angola.
