How Many Countries in America Have Yellow Fever?

Yellow fever is a viral disease that is transmitted through the bite of infected mosquitoes, particularly the Aedes aegypti mosquito. This disease can cause serious illness and even death, with symptoms including fever, chills, headache, muscle aches, and vomiting. When it comes to the spread of yellow fever, it is important to note that the disease is endemic in certain parts of the world, including several countries in America.

These countries have areas that are classified as high-risk for yellow fever transmission, particularly in rural and forested areas. Travelers to these regions are often advised to get vaccinated against yellow fever to protect themselves from the disease, as well as to prevent its spread to other parts of the world.
