A UN medical worker infected with Ebola has died at a hospital in Germany.

Doctors at the hospital in Leipzig said the man, 56, originally from Sudan, died despite receiving experimental drugs to treat the virus.

More than 4,400 people have died from the outbreak, mainly in West Africa.

The rate of new cases at some of the "epicentre" areas has slowed down, the World Health Organization says, but the number of cases in the capitals of the worst-affected countries is rising.

Senior WHO official Bruce Aylward told reporters on Monday that the outbreak was also continuing to spread geographically to new districts in the capitals of Sierra Leone, Liberia and Guinea.
