The US Centers for Disease Control has a page about the history of U.S. Quarantine Stations,
They are staffed with medical and public health officers from the Centers for Disease Control and Prevention (CDC) and managed by CDC’s Division of Global Migration and Quarantine. These health officers decide whether ill persons can enter the United States and what measures should be taken to prevent the spread of contagious diseases.
DGMQ currently staffs 18 of CDC’s 20 quarantine stations. Dallas and Boston fall under the jurisdiction of the quarantine stations in Houston and New York respectively.
There used to be 55 quarantine stations, so why are there only 20 now?
* 1967 CDC (National Communicable Disease Center) took over federal quarantine functions in 1967.
* 1970s CDC reduced the number of quarantine stations from 55 to 8 because infectious diseases were thought to be a thing of the past.
Thanks, Obama.
