What is Yellow Fever?  Yellow fever is a serious disease caused by the yellow fever virus. It is spread through the bite of an infected mosquito and cannot be spread directly from person to person. It is found in certain parts of Africa and South America.
 
Who is at risk?  Those traveling to yellow fever-endemic areas are at risk.
 
How can I protect myself?  As with any disease transmitted by mosquitoes, precautions and insect repellent are recommended to prevent exposure to yellow fever virus. Precautions include remaining in well-screened areas, wearing clothing that covers most of the body, and using effective insect repellent containing DEET. If traveling to endemic area, you should receive the yellow fever vaccine.

The yellow fever vaccine is a live, weakened virus. It is given as a single shot and may be given at the same time as most other vaccines.   The yellow fever vaccine is generally recommended for persons 9 months through 59 years of age who are traveling to or living in an area where risk of yellow fever is known to exist, or if traveling to a country with an entry requirement for the yellow fever vaccine.   Always consult your physician or travel health professional regarding appropriateness for you.  Travelers 60 years of age or older who must travel to a yellow fever area should discuss the yellow fever vaccine with their doctor.
