"Yellow fever, an acute viral disease, is estimated to have been responsible for 78,000 deaths in Africa in 2013 according to new research published in PLOS Medicine this week. The research by Neil Ferguson from Imperial College London, UK and colleagues from Imperial College, WHO and other institutions also estimates that recent mass vaccination campaigns against yellow fever have led to a 27% decrease in the burden of yellow fever across Africa in 2013."^^<http://www.w3.org/2001/XMLSchema#string>
