Yellow fever is a tropical disease that is spread to humans by infected mosquitoes, and although most infections are mild, the disease can be severe and life threatening (Yellow pp). Found in Africa and South America, yellow fever is preventable by immunization and travelers to those countries are advised to get the vaccine (Yellow pp).

These mosquitoes have adapted to living among humans in cities, towns, and villages and are known to breed in discarded tires, flower pots, oil drums, and water storage containers close to human dwellings (Yellow pp).
