COVID Alert DE alerts app users who are not fully vaccinated of potential exposure, even before they may experience symptoms, so they can act quickly and take the steps needed to protect themselves and others. Knowing about a potential exposure allows you to self-quarantine immediately, get tested, and reduce the potential exposure risk to your family, friends, neighbors, co-workers or fellow students who are not fully vaccinated. The more people in Delaware who use COVID Alert DE, the greater the likelihood that you will receive timely anonymous exposure alerts that will ultimately lead to slowing the spread of COVID-19 and protecting others.
