The World Health Organization (WHO) says the Ebola outbreak in the Democratic Republic of Congo is spreading south to areas where there is a greater risk of conflict.
The WHO said most of the cases reported this year have been in Katwa, south of the original centre of the outbreak, the eastern city of Beni.
There have also been cases recorded in the Kayina health zone, where fighting has made it difficult for health workers to monitor potential cases.
Kayina lies on the main route into the city of Goma on DR Congo’s border with Rwanda, and the WHO said it would now send teams to Rwanda to boost preparedness there.
Almost 450 people have died during the current outbreak, which began in August.
