Vanderburgh Co. Health Dept. COVID-19 Update: Duration of Transmission-Based Precautions and Contact Tracing for Antigen Testing

On July 28, 2020, the Indiana State Department of Health (ISDH) released an Indiana Health Alert Network Notification no longer recommending the use of the testing-based strategy to discontinue isolation or precautions for individuals with COVID-19 infection.

The Vanderburgh County Health Department, along with the ISDH and the Centers for Disease Control and Prevention (CDC) support using a symptom-based strategy to end isolation and precautions for persons with COVID-19.

Recommendations using the symptom-based strategy on duration of isolation and precautions:

  • Duration of isolation and precautions:
    • For most persons with COVID-19, isolation and precautions can be discontinued when:
      • At least 10 days have passed since symptom onset or 10 days have passed since the sample collection date if asymptotic AND
      • Fever free for 24 hours without the use of fever reducing medications AND
      • Improvement in symptoms

Retesting of lab confirmed positive individuals is not recommended within 3 months after the date of symptom onset for the initial COVID-19 infection. Serologic testing should not be used to establish the presence or absence of SARS-CoV-2 infection or reinfection.
