The CDC's Quarantine Activity Reporting System seek to limit the importation of infectious diseases into the United States by working with key partners to identify ill persons and potentially infectious items. Quarantine Stations enter reports into the system in real time to CDC-Atlanta that summarizes port activities at 20 ports of entry and land-border crossings where international travelers arrive. The reports are analyzed and evaluated daily and relevant information is captured and disseminated as part of a Disease and Activity Report which is sent to CDC leadership and relevant external partners.
