Prevention and Support


The best way to protect yourself from COVID-19 and spreading it to others is to get vaccinated and practice the Five Core Actions.

For more information on the COVID-19 vaccine, visit our vaccine page here.



If you test positive for COVID-19, immediately isolate and begin to notify your close contacts of their need to quarantine. Do not wait for a call from public health, as not all cases will get a call from the health department.

Due to increasing case volume, the Tennessee Department of Health (TDH) and Knox County Health Department (KCHD) have implemented CDC recommendations for prioritizing investigations and monitoring. This is in an effort to strategically allocate our resources, gather the most essential information quickly and keep the most vulnerable populations protected.

COVID-19 affects people in different ways. That's why it's important to know the full spectrum of symptoms that can occur if you have COVID.  Remember, symptoms can be mild to severe and you may only have a few of these symptoms. Just because your symptoms are mild doesn't mean you can't spread the virus to others. For a full list of symptoms, click here.

Medical Providers:

Provide your patients with the isolation and quarantine guidance in the blue boxes below if they test positive for COVID-19 or if they are a close contact to a confirmed case. If your patient tests positive for COVID-19, they are to immediately isolate and begin to notify their close contacts of their need to quarantine.


Employers are encouraged to provide access to sick leave, telework and other accommodations without individual documentation from a doctor or nurse regarding an individual's need to stay at home as a result of a COVID-19 exposure or diagnosis. It is incredibly important that individuals take personal responsibility and businesses/employers utilize their standard infection control procedures to implement proper safety precautions, based on the guidance below. Individuals identified as a confirmed case or a close contact should refrain from reporting to work until their isolation/quarantine period is over.
