The Transition Away from Universal Case Investigation & Contact Tracing for Individual Cases of COVID-19 by Public Health Agencies

ATLANTA and ARLINGTON, Va., Jan. 26, 2022 /PRNewswire/ — The Association of State and Territorial Health Officials (ASTHO), Council of State and Territorial Epidemiologists (CSTE), National Association of County and City Health Officials (NACCHO), Big Cities Health Coalition (BCHC), and Association of Public Health Laboratories (APHL) support state, local, territorial, and tribal health departments in transitioning away from universal case investigation and contact tracing at this point in the COVID-19 pandemic to a more strategic approach of outbreak investigations and targeted case investigations. Although universal case investigation and contact tracing was implemented in spring 2020 to slow COVID-19 transmission, much has changed over the past year prompting the need for a revised public health approach. This includes the wide availability of safe and effective vaccines, better understanding of the epidemiology of the SARS-CoV-2 virus, and the emergence of the more infectious Omicron variant.

While universal case investigation and contact tracing during the initial phase of the pandemic was justified in the attempt to contain the pandemic, most experts agree this is no longer optimal. We urge a refocus of our public health efforts and resources, with an emphasis on targeting investigations in higher risk settings serving vulnerable populations and other critical measures to better protect the public.

Although it is no longer optimal for public health to universally investigate and monitor individual COVID-19 cases and their contacts, contact tracing remains a necessary public health tool for interrupting ongoing transmission of COVID-19 and preventing disease in the most vulnerable populations, especially in certain higher risk congregate residential settings (e.g., correctional facilities and nursing homes) or in other specific situations, such as outbreak investigations or if warranted based on concerning changes in the clinical or epidemiological characteristics of the virus. Individual jurisdictions may also consider continuing contact tracing in other settings, including schools and child-care centers.

The recommended transition away from universal case investigation and contact tracing for COVID-19 does not suggest these tools have limited value in the setting of many priority infectious diseases. Indeed, case investigation and contact tracing by public health officials remains a vital, well-established method for the control of other communicable diseases, such as measles, HIV, and sexually transmitted diseases, like gonorrhea.
