GENEVA (AP) - An outbreak of Rift Valley Fever in Sudan has killed 164 people, the World Health Organization said Thursday.
Rift Valley Fever is normally a mild disease in humans with a fatality rate of around one percent. But in patients who develop the hemorrhagic fever form, the fatality rate is around 50 percent, according to the U.N. health agency.
More than 221 people caught the virus over the last two weeks, bringing the total number of cases to 451, including those who died.
