Contact tracing, for example, is a focused strategy for breaking transmission chains and controlling the spread of disease.
It involves identifying infected persons; taking steps to prevent an infected person from further spreading infection, whether through isolation or treatment, if an effective treatment option exists; identifying those with whom the infected person may have been in close contact while infectious; and, finally, locating and testing these close contacts.
If a close contact is found to be infected, the disease-investigation process starts again.
The Centers for Disease Control's Ebola control strategy illustrates how contact tracing can work.
Being within six feet of someone for a prolonged period; or caring for, visiting, or living with a Covid-19 infected person, qualifies as close contact.
To work effectively contact tracing depends on certain preconditions-especially no existing barriers to testing.
Contact tracing is most effective as a means of containing flareups.
