How was malaria eradicated from the United States?
Malaria was eradicated in the United States between 1947 and 1951 through the National Malaria Eradication Program; a cooperative undertaking initiated by the state and local health agencies of 13 Southeastern states and the Center for Disease Control and Prevention (CDC). On July 1, 1947, the program began to systematically apply DDT to the interior surfaces of rural homes or entire premises in counties where malaria was reported to have been in recent years. This initiative proved successful, by the end of 1949, more than 4,600,000 DDT house spray applications had been made. However, total elimination of transmission of malaria in the US took longer to achieve. In the year 1951, malaria was considered eradicated from the United States.
