Overview

Yellow fever, (known historically as yellow jack, yellow plague, or bronze john), is an acute viral disease. In most cases, symptoms include fever, chills, loss of appetite, nausea, muscle pains particularly in the back, and headaches. Symptoms typically improve within five days. In some people within a day of improving, the fever comes back, abdominal pain occurs, and liver damage begins causing yellow skin. If this occurs, the risk of bleeding and kidney problems is also increased.

The disease is caused by the yellow fever virus and is spread by the bite of the female mosquito. It infects only humans, other primates, and several species of mosquitoes. In cities, it is spread primarily by mosquitoes of the Aedes aegypti species. The virus is an RNA virus of the genus Flavivirus. The disease may be difficult to tell apart from other illnesses, especially in the early stages. To confirm a suspected case, blood sample testing with polymerase chain reaction is required.

 

Changes in the way humans live and work, and the resurgence of mosquito vectors, particularly the aedes aegypti mosquito (which spreads Zika, dengue fever and chikungunya), have raised the global risk of yellow fever. Two large yellow fever outbreaks- in Angola and the Democratic Republic of Congo are now under control but these are just warnings of bigger outbreaks to come if action is not taken. A coalition of partners working to stop yellow fever outbreaks met in Geneva on September 12 to develop a new strategy - Eliminating Yellow fever Epidemics (EYE). This strategy aims to protect the populations most at risk, ensure a ready supply of yellow fever vaccine, build resilience in urban centres and prevent international spread.
