- Few Americans realize that yellow fever was not always a disease of the faraway tropics. In 1878, an outbreak of yellow fever—the virus carried to the United States in mosquitoes from Africa—killed 20,000 people in the Mississippi Valley.

- Although mass vaccination campaigns in Africa between the 1940s and 1960s led to the near disappearance of yellow fever, inadequately immunized populations and urbanization set the stage for the disease to reemerge. By the 1990s, there were an estimated 200 000 annual cases, with 30 000 deaths.
