Contact tracing is an important component of infectious disease control, particularly for COVID-19 which has a high transmission rate. Public health professionals call patients who test positive for COVID-19 and ask them about any close contacts they may have had during their infectious period. The infectious period generally begins 48 hours before becoming symptomatic or testing positive and extends until the patient is isolated. A close contact is considered anyone who was six feet or closer to an infected person for at least 15 minutes. Public health professionals will then reach out to the close contacts, while protecting the initial (index) patient’s privacy, and educate them about testing and quarantine measures.
