The announcement came as a new infection brought to 25 the number of people confirmed to be carrying the disease in addition to the 10 others who have died from the hemorrhagic fever.

A further 187 suspected cases will remain under medical observation until each has reached the end of their respective potential incubation periods without developing any symptoms of the disease.

WHO says that while there is now strong clinical and epidemiological evidence to suggest that the outbreak is slowing, identifying and isolating all suspect cases is still a priority for the response teams to ensure that the chains of transmission are broken.

This includes following up on any contacts over the incubation period in order to isolate them immediately if they become ill, WHO says.

Health experts caution that the epidemic will not be declared over until two 21-day incubation periods pass without a new reported case.
