Illness ranges from a fever with aches and pains to severe liver disease with bleeding and yellowing skin (jaundice). Yellow fever is a viral disease spread to humans, as well as between certain other primates and humans, by the bite of infected mosquitoes. Predicting where epidemics might occur must take into account local mosquito populations and specific YF virus strain, as well as ecoclimatic conditions, sociopolitical and demographic factors including population size, density, and mobility, and vaccine coverage. The vaccine does not contain antibiotics, preservatives or gelatin. The yellow in the name is explained by the jaundice that appears in some patients. Yellow fever is a persistent problem in West Africa, where the virus cycles between monkeys and mosquitoes and spills over to humans. [Google Scholar] Smith HH.
