KAMPALA, Uganda, Dec. 3 (AP)  Three more people have died from a new strain of the Ebola virus in Uganda, bringing the death toll to 19, health officials said Monday.

Officials said health workers in the area were fleeing their jobs.

The disease has been detected in five districts in western Uganda, said Dr. Sam Zaramba, director general of Uganda’s health service.

Tests showed the virus belongs to a different subtype than the four already known, the World Health Organization said.
