The World Health Organization reported that the outbreak yellow fever in Sudan's Darfur region, which has already claimed at least 165 lives, is the worst that Africa has seen in decades. According to Anshu Banerjee, the WHO's representative to Sudan, the current outbreak may be considered as the worst since 1990. As of September 2 this year, a total of 732 suspected yellow fever cases have been reported in Darfur, including 165 fatalities. Similar outbreaks in other nations are at smaller scales because regular vaccination campaigns have begun to include yellow fever, while Darfur never had the same program against the deadly virus until last month. United Nations humanitarian coordinator Ali al-Za'tari said the outbreak is alarming and there are no signs that the spread of the virus is slowing down. He said that vaccinating all people at risk is the only way to stop the further spread of the disease. A vaccination program was launched on November 20 in the 12 hardest hit areas of Darfur. The initial phase of the program targeting about 2.2 million people is nearly complete. Banerjee said over a million more doses will arrive next week. ubAlert
