COVID-19 Exposure Notifications are now available for Maryland. The notification system is an API developed by Apple and Google in conjunction with health departments to help alert individuals who may have been exposed to COVID-19. For privacy reasons, these alerts are turned off by default but you can turn them on if you’d like to be notified.
On iOS, go to Settings -> Exposure Notifications
On Android, go to Settings -> Google -> COVID-19 Exposure Notifications
