In 1949, the office of Malaria Control The U.S. was declared free of malaria as a significant public health problem. By 1951, CDC gradually withdrew from active participation in the operational phases of the program and shifted its interest to surveillance, and in 1952, CDC participation in operations ceased altogether.

The National Malaria Eradication Program was a cooperative undertaking by state and local health agencies of 13 southeastern states and the Communicable Disease Center of the U. S. Public Health Service, originally proposed by Dr. L. L. Williams. The program commenced operations on July 1, 1947.
