Prevention and Support


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

Following these actions are critical and will help protect our community until a vaccine is widely available. 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, laboratory processing times, and continuing challenges with laboratory reporting systems, 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 the need to quarantine.


Public Health will no longer be able to provide proof of quarantine or ‘return-to-work’ letters for everyone. Because of this, 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. By following this guidance, businesses can also supplement the contact tracing process by conducting it within their organization. Individuals identified as a confirmed case or a close contact should refrain from reporting to work until their isolation/quarantine period is over.

Employees, if your employer requests a ‘return-to-work’ letter, this document (In Spanish) from KCHD can be used to explain the process changes listed above and why such letters will not be provided moving forward.
