Biology

Yellow fever is a viral infection that occurs mainly in Central Africa and in the Amazon region of South America. It is prevented through vaccination and transmitted by many species of mosquitoes of the Aedes genus, including Aedes aegypti e Haemogogus. The infection causes clinical manifestations that range from asymptomatic cases to lethal fulminating cases. Generally the disease begins with fever, chills, malaise, headache, nausea and evolves to jaundice (increase of bilirubin in blood, after which the disease is named), mucosal and internal hemorrhages, hemorrhagic vomiting and renal failure. 

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