Quarantine and Isolation
Isolation and quarantine help protect the public by preventing exposure to people who have or may have a contagious disease.
Twenty U.S. Quarantine Stations, located at ports of entry and land border crossings, use these public health practices as part of a comprehensive Quarantine System that serves to limit the introduction of infectious diseases into the United States and to prevent their spread.

On February 12, 2013, the Department of Health and Human Services (HHS) and the Centers for Disease Control and Prevention (CDC) published a final rule establishing a user fee for filovirus testing of nonhuman primates (NHPs). According to the final rule, CDC will charge a $540 user fee to cover the costs for testing of NHP samples submitted to the CDC. Filovirus antigen-capture testing is required for all Old World NHPs that die for any reason other than trauma during the mandatory 31-day quarantine period or that have illness consistent with filovirus infection. This rule became effective on March 14, 2013.
U.S. Quarantine Stations are located at 20 ports of entry and land-border crossings where international travelers arrive. They are staffed with quarantine medical and public health officers from CDC. These health officers decide whether ill persons can enter the United States and what measures should be taken to prevent the spread of infectious diseases.
