OAKLAND, Caliph. (Reuters) – North Dakota, Wyoming and Alabama are the latest U.S. states to launch apps to warn users about potential exposure to the new coronavirus by following their conversations, state officials told Reuters on Thursday.
Virginia became the first U.S. state last week to advise residents to download such an app using technology developed by smartphone software giant Apple Inc. (AAPL.O) and Alphabet Inc’s (GOOGL.O) Google.
Some 316,000 people have downloaded Virginia’s COVIDWISE app, state health official Jeff Stover told Reuters during an online event hosted by the Responsible Data Foundation as part of a series on pandemic-related technology.
North Dakota launched its app, Care19 Alert, on Thursday and Wyoming will release an app on Friday, Tim Brookins, whose company ProudCrowd developed the apps, also said during the event.
Alabama, which has tested its app among some college students and staff, plans to market it statewide Monday, said Sue Feldman, director of graduate programs in health informatics at the University of Alabama at Birmingham.
Washington, which recently tested its app in a hospital, and Pennsylvania are among other states that could formally launch apps using Apple-Google technology in the coming weeks.
The technology enables phones to exchange Bluetooth signals to keep an anonymous list of nearby meetings. An infected user can anonymously inform recent contacts to be tested as quarantine.
But developers acknowledge that they still face challenges in convincing users that tracking and notification systems are private and reliable.
For example, getting in touch with apps from different states to communicate with each other because users cross borders is not testing with the North Dakota app now the first and only one in the US to support that functionality.
