Causes

 Yellow fever is caused by a virus (Flavivirus) that is spread by the Aedes aegypti mosquito
  • Humans and monkeys are most commonly infected with the yellow fever virus
  • When a mosquito bites a human or monkey infected with yellow fever, the virus enters the mosquitos bloodstream and circulates before settling in the salivary glands
  • When the infected mosquito bites another monkey or human, the virus then enters the hosts bloodstream, where it may cause illness
  • Yellow fever cannot be spread by close contact between two people
