The Ebola outbreak in the east of the Democratic Republic of Congo could last at least another four months, the World Health Organization (WHO) says, Reuters news agency reports.

Peter Salama, the WHO’s head of emergency response, has warned that the virus could spread to neighbouring Rwanda or Uganda.

He told Reuters that he is most concerned with the situation in Beni, in the east of the DR Congo, where people who may be carrying the virus are hiding from health workers.

The WHO says that 122 people have died from Ebola in the current outbreak which began at the end of July.
