Yellow fever is a virus transmitted by female mosquito bites, as well as contact with some primates. People who contract the disease generally experience fever, body aches, and nausea with vomiting for several days.
After the initial infection period, some patients go on to heal without any long-term health problems, but some enter a second, toxic phase. The toxic phase causes liver damage, and jaundice that results is the reason for the name "yellow fever."
It is also classified as a hemorrhagic fever in the same category as dengue, Ebola, and some strains of encephalitis-because this toxic phase of the disease also causes an increased risk of bleeding.

Victims may experience internal bleeding and vomit blood, and other symptoms of progressed include delirium, seizures, kidney and liver failure, and coma leading to eventual death.
The World Health Organization reports approximately 30,000 deaths annually, and, since the 1980s, the Center for Disease Control has noted an increase in cases and classified it as a reemerging virus. In response, many effected countries instituted a vaccination requirement for visitors.
Since there is no current known cure for it, prevention is key. Some important practices to consider when protecting against insect-borne disease include utilizing insect repellent, hanging mosquito netting in sleeping areas, and wearing long-sleeved clothing.
Once you're vaccinated, your travel doctor will issue an international certificate proving that you've been vaccinated, which is good for ten years.
In rare cases, if a traveler must be exempt from the vaccination requirement for health reasons, medical waivers that are accepted by most countries can be issued, but these travelers then remain at risk of contracting yellow fever and need to take extra care to avoid insect bites leading to possible infection.
