Yellow fever is a disease that is spread by mosquitoes. Unlike malaria, also carried by mosquitoes, yellow fever is not found in Southern Asia. This disease is almost exclusively found in Northern Africa (68% of cases) and South America (31% of cases).
Yellow fever is also known as black vomit (vomit negro in Spanish). Both of these names describe some of the more severe symptoms. “Yellow fever” due to the fever and jaundice that can occur. “Black vomit” because of the congealed blood in the sick of its victims.
A vaccine against yellow fever exists, but not everyone has access to this. 1 in 10 yellow fever cases lead to death.
