The World Health Organization (WHO) says it is hoping to work with the government in the Democratic Republic of Congo to conduct trials using five experimental drugs in order to discover the most effective medicine to limit the spread of Ebola outbreaks.
The WHO says it is cautiously optimistic about the situation in DR Congo after vaccinating more than 800 of the 900 people who have come into contact with Ebola patients.
Twenty-five people are reported to have died during the current outbreak of the virus.
