COVID Defense is an easy-to-use app created by the Louisiana Department of Health. COVID Defense protects your privacy while helping protect you from COVID-19. You will get an alert if you are in close contact with someone who tests positive for COVID-19.

By adding this free app to your phone, you join thousands of people helping to protect one another from COVID by knowing if you've been exposed.

The COVID Defense app was built using an open-source project developed by PathCheck Foundation.
