Transmission of Yellow Fever

Yellow fever is primarily transmitted through the bites of infected mosquitoes, particularly the Aedes aegypti species. When an infected mosquito bites a person, it can pass on the virus, leading to infection. The virus can also spread between monkeys and humans in certain areas. Though it cannot be spread directly from person to person, outbreaks can occur in regions where mosquito populations are high, especially in tropical and subtropical areas. Vaccination is key in preventing yellow fever, as there is no specific treatment once someone is infected.
