Get and Keep America Open: Supporting states, tribes, localities, and territories
Revisions were made on May 29, 2020 to Health Departments: Interim guidance on developing a COVID-19 case investigation & contact tracing plan to reflect the following:
The contact elicitation window for asymptomatic cases was changed from 10 days before obtaining the specimen that tested positive for COVID-19 to 2 days to accommodate pragmatic and operational considerations for the implementation of case investigation and contact tracing programs. Additionally, recent data suggests that asymptomatic persons may have a lower viral burden at diagnosis compared to symptomatic cases. Thus, the longer contact elicitation window (beginning 10 days prior to specimen collection) may have limited impact in identification of new COVID-19 cases. Furthermore, the recommendation for the shorter contact elicitation window (beginning 2 days prior to specimen collection) will help focus case investigation and contact tracing resources towards activities most likely to interrupt ongoing transmission. This time period is also now in alignment with WHO, European CDC, and Public Health Canada.
Revisions were made on May 22, 2020, to reflect the following:
- New guidance resource available (see “Guidance” section below): Key Information to Collect During a Case Interview
Revisions were made on May 15, 2020, to reflect the following:
- New guidance document available (see “Guidance” section below): Health Departments: Interim guidance on developing a COVID-19 case investigation & contact tracing plan
CDC guidance for COVID-19 may be adapted by state and local health departments to respond to rapidly changing local circumstances.
- Trace and monitor contacts of infected people. Notify them of their exposure.
- Support the quarantine of contacts. Help ensure the safe, sustainable and effective quarantine of contacts to prevent additional transmission.
- Expand staffing resources. Contact tracing in the US will require that states, tribes, localities and territorial establish large cadres of contact tracers.
- Use digital tools. Adoption and evaluation of digital tools may expand reach and efficacy of contact tracers.
