Today, Virginia launched a COVID-19 exposure notification app that will alert users if they have been in close contact with an individual who has tested positive for COVID-19. Get your free download: iPhone | Android.
Called COVIDWISE, this public health app balances the need for robust contact tracing with protecting user privacy. The app is the first to use Bluetooth Low Energy technology developed by Apple and Google, which does not use personal information or location data. Users opt-in to download and utilize the free app. If a user chooses to share their positive test result, they will use a pin number provided by the Virginia Department of Health instead of any personal identifiers.
“As COVID-19 cases continue to be identified across the Commonwealth, it is important for people to know whether they have been exposed to someone who has tested positive for the disease,” said State Health Commissioner M. Norman Oliver, MD, MA. “COVIDWISE will notify you if you’ve likely been exposed to another app user who anonymously shared a positive COVID-19 test result. Knowing your exposure history allows you to self-quarantine effectively, seek timely medical attention, and reduce potential exposure risk. The more Virginians use COVIDWISE, the greater the likelihood that you will receive timely exposure notifications that lead to effective disease prevention.”
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.
Individuals who test positive for COVID-19 will be notified by a VDH case investigator and will be given a unique numeric code. This code is entered into the app by the user and serves as verification of a positive report. Others who have downloaded COVIDWISE and have been in close proximity to the individual who reported as being positive will receive a notice which reads, “You have likely been exposed to someone who has tested positive for COVID-19.” This is your alert to get tested.
The notice includes the estimated number of days since the exposure and provides several options for taking further action, including contacting a primary care physician or local health department, monitoring symptoms, and finding nearby test locations. The Virtual VDH tab within the app also provides links to online resources and relevant phone numbers.
Anyone who downloads the app has the option to choose to receive exposure notifications, and if a person is diagnosed with COVID-19, it is up to them whether or not to share their result anonymously through COVIDWISE. No location data or personal information is ever collected, stored, tracked, or transmitted to VDH as part of the app. Users have the ability to delete the app or turn off exposure notifications at any time.
Widespread use is critical to the success of this effort, and VDH is launching a robust, statewide public information campaign to make sure Virginians are aware of the COVIDWISE app, its privacy protection features, and how it can be used to support public health and help reduce the spread of the virus.
The Virginia Department of Health (VDH) developed COVIDWISE in partnership with Spring ML using funding from the federal CARES Act. COVIDWISE is the only app in Virginia allowed to use the exposure notifications system (ENS) application programming interface (API) jointly created by Apple and Google. Other countries, including Ireland and Germany, have successfully used this technology in similar apps.
