You will begin showing symptoms of yellow fever about three to six days after being bitten by an infected mosquito. These symptoms include fever, chills, backache, nausea, headache, and vomiting. Jaundice, or yellowing of the skin and eyes, is the hallmark of the infection and gives it its name.
Most people recover from yellow fever in three to four days. In more severe cases, the virus might cause bleeding, heart problems, liver or kidney failure, or brain dysfunction. Yellow fever can be fatal. People with the disease may be able to ease their symptoms, but there is no specific medical treatment.
Yellow fever is caused by the yellow fever virus, which is spread by infected Aedes mosquitoes.
Who's at Risk?
Yellow fever occurs only in Africa and South America, so only travelers who are destined for these regions need to be concerned about it. The World Health Organization estimates there are 200,000 cases of yellow fever every year (although the organization says the vast majority of cases are not reported), and 30,000 of those cases are fatal. The elderly are at highest risk of developing the most severe symptoms of the infection.
If you are traveling to high-risk areas of sub-Saharan Africa or tropical South America, you can take some precautions to help keep yellow fever at bay. First, and most importantly, you should get a yellow fever vaccination. Talk with your physician about the vaccine at least two weeks before you travel. The vaccine is only available at authorized locations; call your local health department or visit www2.ncid.cdc.gov/travel/yellowfever to find the one nearest you.
The traveling infections you've read about here -- cholera, hookworms, dengue, malaria, diarrhea, typhoid and yellow fever -- are not as prevalent now in the developed world as they were hundreds of years ago, but they can still ruin your vacation, or worse. So study up on traveling diseases and know how to protect yourself.
