Osmosis video - Yellow fever virus

Yellow fever virus is a single-stranded RNA virus from the flaviviridae family. It is typically found in parts of Africa and South America and is primarily transmitted by the Aedes aegypti mosquito. While many people who contract the virus may not show any symptoms, some individuals may experience more severe symptoms involving the liver and kidneys, such as jaundice, upper abdominal pain, vomiting that looks like coffee grounds, and decreased or no urine output. To prevent yellow fever, a live attenuated yellow fever vaccine is available, and treatment generally consists of supportive measures.
