It is transmitted to humans through the bite of an infected mosquito. It’s a rare form of illness in U.S. travelers. Even so, illness ranges in severity from a self-limited febrile sickness to severe liver disease with bleeding. Yellow fever is diagnosed based on symptoms, laboratory testing, physical findings, and travel history, including the possibility of exposure to infected mosquitoes.
The yellow fever virus is transmitted primarily through the bite of infected mosquitoes. Infected primates are the hosts of the virus. The mosquitoes bite the infected primates and then bite others (human and non-human), thus spreading the disease. Humans become contagious shortly before the onset of fever and for 3–5 days after initial onset.
When a person becomes infected, it typically takes 3–6 days for symptoms to appear.
If a person over the age of nine months is traveling to or living in areas at risk for yellow fever virus like South America and Africa, they should get the yellow fever vaccine.
Take steps to avoid mosquito bites:
If you feel you are at risk of being exposed to pertussis, get vaccinated immediately. The pertussis vaccine is available in combination with the tetanus and diphtheria vaccines in two formulations – the Diphtheria, Tetanus and Pertussis Vaccine (DTaP) and the Tetanus, Diphtheria and Pertussis Vaccine (Tdap). Both immunizations are available at your local Rite Aid.There is no specific treatment for patients with yellow fever. Patients who become infected should be hospitalized for supportive care and observation. Rest, fluids, and use of pain relievers and medication to reduce fever may help relieve these symptoms. Using certain medications, such as aspirin or other non-steroidal, anti-inflammatory drugs may increase the risk of bleeding. Yellow fever patients should stay indoors and away from mosquitoes during the first few days of illness. This way, other mosquitoes cannot be infected and spread the virus. The majority of people who become infected will have mild symptoms with complete recovery. Once people recover from yellow fever, they are usually immune to repeat infections.
