Fourth member of the U.N. mission in Liberia, the country hardest-hit by the Ebola epidemic, has been hospitalized after testing positive for the deadly virus that has killed more than 7,500 people in West Africa in the worst-ever outbreak of the disease. "This is the fourth case of Ebola in the mission, and UNMIL personnel continue to mourn the deaths of two colleagues who died from the disease only three months ago," a U.N. statement said Wednesday, referring to the U.N. Mission in Liberia. Liberia tops the number of Ebola deaths with nearly 3,400 fatalities but has seen a clear decrease of new transmissions in the past month. The death toll from Ebola in Liberia, Sierra Leone, and Guinea has risen to 7,573 out of 19,463 confirmed cases, the World Health Organization (WHO) reported Wednesday.
