The World Health Organization (WHO) says a doctor infected with Ebola in the Democratic Republic of Congo is in an area entirely surrounded by rebels.
The WHO’s deputy director general, Dr Peter Salama, said this was a problem health workers had been dreading.
“It is the first time we have a confirmed case and contacts in an area of high insecurity. It is really the problem we were anticipating and at same time dreading,” Dr Salama told a news briefing in Geneva.
The doctor is in hospital in the eastern town of Oicha, which is surrounded by a Ugandan Islamist militia, the Allied Democratic Forces.
A total of 97 people he has been in contact with are in the same area, which health teams are unable to access because of security concerns.
The WHO says nearly 40 people are confirmed to have died in the current outbreak.
