Three patients infected with the deadly Ebola virus escaped from a hospital holding them in quarantine in the Congo city of Mbandaka, an aid group said.
Two of the patients got out on Monday but were found dead a day later, said Henri Gray, the head of the Medecins Sans Frontieres (MSF) mission in the city.
Another left on Saturday, but was found alive the same day and is now under observation, Gray added.
“This is a hospital. It’s not a prison. We can’t lock everything,” he said.
