The deadly Ebola virus has continued to spread in Liberia, where a further three people died from the disease, bringing the total number of suspected deaths to 10, dpa quoted the health ministry as saying Monday. The total number of people infected with Ebola in the West African nation rose to 21 from 14 last week. The United States Department of Defense agreed to set up two Ebola testing centres in Liberia to help control the outbreak. Ebola entered Liberia from neighbouring Guinea, where 84 people have died of the virus since February and 134 further cases have been confirmed. The virus, for which there is neither vaccination nor cure, has also spread to Sierra Leone and Mali.
