Initially, they screen everyone with both rapid antigen and rapid antibody testing. This factory can routinely perform these cheap rapid antigen tests on the remaining employees every three days to detect new infections. The rapid antigen test comes positive when the person has high viral loads -- and is the most infectious to others. Regular rapid antigen testing will also diagnose cases early on at the viral phase which will prompt monitoring of symptoms to head off the more severe outcomes. Rapid testing will be a cheaper option to lockdowns, institutional quarantine, and contact tracing.
