The Shot Nurse is a Tennessee State Certified provider of the Yellow Fever Vaccination
Yellow fever vaccine is given only at approved vaccination centers. After receiving the vaccine, you will receive aInter-national Certificate of Vaccination (yellow card) that has been validated. This Certificate becomes valid 10 days after vaccination and lasts for 10 years. You will need this card as proof of vaccination to enter certain countries. Visit the CDC's travel information website at http:// www.cdc.gov/travel to learn the travel requirements for different countries.
Please make sure you discuss your travel itinerary with the nurse before you receive your yellow fever vaccination.
If you continue to live or travel in yellow fever-endemic areas, you should receive a booster dose of yellow fever vaccine after 10 years. Yellow fever vaccine may be given at the same time as most other vaccines.
Yellow fever is a viral disease that is transmitted to humans through the bite of infected mosquitoes. Yellow fever occurs in tropical regions of Africa and in parts of South America. Yellow fever is a very rare cause of illness in the U.S. The last epidemic of yellow fever in North America occurred in New Orleans in 1905.
What causes yellow fever?
Yellow fever is caused by infection with yellow fever virus, which is transmitted by the bite of infected mosquitoes.
What can people do to prevent becoming infected with yellow fever virus?
Yellow fever can be prevented by vaccination. Travelers should also take precautions against mosquito bites when in areas with yellow fever transmission.
Travelers should get vaccinated for yellow fever before visiting areas where yellow fever occurs. In the United States, the vaccine is given only at designated yellow fever vaccination centers. International regulations require proof of yellow fever vaccination for travel to and from certain countries. People who get vaccinated should be given an International Certificate of Vaccination.
Where does yellow fever virus occur?
The geographic range of the virus is South America and Africa. For information on current outbreaks, consult CDC's Travelers' Health website (www.cdc.gov/travel). Given the current yellow fever epidemics and the world wide distribution of Aedes aegypti, there is a risk of importation of yellow fever into new areas by infected travelers.

Avoid mosquito bites when traveling in tropical areas. Mosquitoes that spread yellow fever usually bite during the day, especially at dusk and dawn.
When outside: Wear long-sleeved clothing and long pants. For extra protection, treat clothing with the insecticide permethrin. Use insect repellent on exposed skin. Repellents containing DEET (N,N-diethylmetatoluamide), Picaridin (KBR 3023), IR 3535, p-Menthane 3,8-diole (PMD or oil of lemon eucalyptus) are effective. Follow application instructions carefully.
Stay in well-screened areas as much as possible.
Spray living and sleeping areas with insecticide.
What is the basic yellow fever transmission cycle?
There are two kinds of yellow fever, spread by two different cycles of infection.
Jungle yellow fever is mainly a disease of monkeys. It is spread from infected mosquitoes to monkeys in the tropical rain forest. People get jungle yellow fever when they are bitten by mosquitoes that have been infected after feeding on infected monkeys. Jungle yellow fever is rare and occurs mainly in persons who live or work in tropical rain forests.
Urban yellow fever is a disease of humans. It is spread by mosquitoes that have been infected by other people. Aedes aegypti is the type of mosquito that usually carries yellow fever from human to human. These mosquitoes have adapted to living among humans in cities, towns, and villages. Their larvae grow in discarded tires, flower pots, oil drums, and water storage containers close to human dwellings. Urban yellow fever is the cause of most yellow fever outbreaks and epidemics.
What type of illness does yellow fever virus cause?
Illness ranges in severity from a self-limited febrile illness to severe hepatitis and hemorrhagic fever. Many yellow fever infections are mild, but the disease can cause severe, life-threatening illness. Symptoms of severe infection are high fever, chills, headache, muscle aches, vomiting, and backache. After a brief recovery period, the infection can lead to shock, bleeding, and kidney and liver failure. Liver failure causes jaundice (yellowing of the skin and the whites of the eyes), which gives yellow fever its name. Severe yellow fever infections can be fatal.
What is the incubation period for yellow fever?
The incubation period (time from infection to illness) is usually 3-6 days.
What is the mortality rate of yellow fever?
Case-fatality rates from severe disease range from 15% to more than 50%.
How is yellow fever treated?
There is no specific treatment for yellow fever. Treatment is symptomatic-rest, fluids, and ibuprofen, naproxen, acetaminophen, or paracetamol may relieve symptoms of fever and aching. Aspirin should be avoided. Infected persons should be protected from further mosquito exposure (staying indoors and/or under a mosquito net during the first few days of illness) so that they can't contribute to the transmission cycle.
