Governor Ralph Northam announced this week the launch of COVIDWISE, an innovative exposure notification app that will alert users if they have been in close contact with an individual who has tested positive for COVID-19.
Virginia is the first state in the country to design a COVID-19 app using Bluetooth Low Energy technology developed by Apple and Google, which does not rely on personal information or location data. Users opt-in to download and utilize the free app.
COVIDWISE works by using random Bluetooth keys that change every 10 to 20 minutes. iOS and Android devices that have the app installed will anonymously share these random keys if they are within close proximity for at least 15 minutes.
Each day, the device downloads a list of all random keys associated with positive COVID-19 results submitted by other app users and checks them against the list of random keys it has encountered in the last 14 days. If there is a match, COVIDWISE may notify the individual, taking into account the date and duration of exposure, and the Bluetooth signal strength which is used to estimate proximity.
