Yellow fever is a viral infection which takes place mainly in the Central Africa and in the Amazon area of South America. It is avoided through vaccination and transmitted by various species of mosquitoes of Aedes genus, including Aedes aegyptie Haemogogus.

The infection causes clinical manifestations which range from asymptomatic cases to lethal fulminating cases. Commonly the disease starts with fever, malaise, chills, headache, nausea and evolves to the jaundice (raise of bilirubin in blood, after which the disease is named), internal and mucosal hemorrhages, renal failure and hemorrhagic vomiting.

Prevention is done by the regular mass vaccination and vaccination of travelers to endemic areas. The combat against the vector mosquito is also a significant prophylactic measure.
