Without a vaccine to prevent the coronavirus the best protection is reduce exposure. Because the virus is spread mainly person-to-person you can prevent the spread by observing physical distancing.
The virus is contracted due to droplet exposure from an infected individual when they cough, sneeze, or talk.
So take care of yourself, your loved ones, and your community by masking up, handwashing, and physical distancing.
Together we can move Knox County back to yellow.
