Periodic screening for COVID infection is one of many proven ways to reduce the spread of COVID-19. Unfortunately it is underutilized.
Although vaccine mandates have become part of many workplaces, there are still those who will not accept vaccination. Periodic COVID testing has become the alternate choice, although predominantly done using a test that takes at least 24 hours to get the results, during which time the person could potentially be spreading the virus. The typical testing interval is a week, although some companies such as FOX news, are mandating daily testing.
One problem with the current approach to COVID testing is that it is predominantly reactive in nature. Testing for the SARS-CoV-2 coronavirus is being done on people with COVID-19 symptoms, but it has not been consistently used as part of a comprehensive plan to reduce the spread of COVID infections.
