The Maryland Department of Health has announced the launch of MD COVID Alert, the official COVID-19 Exposure Notifications Express system. MD COVID Alert uses Bluetooth Low Energy technology to quickly notify users who might have been exposed to someone who tested positive for COVID-19 with the goal of reducing infections in the state. Those with an iPhone or Android smartphone will receive a push notification, inviting them to receive exposure notification alerts. This is voluntary and is available at no cost. Users can disable notifications at any time. For more information, visit covidlink.maryland.gov/mdcovidalert.
