COVID-19 Tests*
Positive 126 5.7%
Negative 2067 94.3%
Total 2193 100.0%
Data Source: National Electronic Disease Surveillance System Base System (NBS)


*The National Electronic Disease Surveillance System Base System (NBS) is a CDC-developed information system that helps public health departments manage reportable disease data and send data to CDC. The testing data referenced above is only comprised of Knox County residents and includes:

  • The number of people KCHD has collected specimens on, based on the consideration of being high-risk;
  • The number of people hospitals and health care providers have tested through the TDH State Lab, based on the consideration of being high-risk;
  • The number of people health care providers have tested through private labs that report through NBS.

The number above does not include every negative test in Knox County. Negative tests are not typically reported to public health for any notifiable disease; therefore, not all labs utilize the NBS system. Because this is not a part of the traditional reporting system, there may be a lag in the reporting of negative cases. Public health typically evaluates the burden of disease compared to the overall population, as you can see here in our last Community Health Assessment.
