OAKLAND, Calif. (Reuters) - North Dakota,
Wyoming and Alabama are the latest U.S. states launching apps to warn
users about potential exposure to the novel coronavirus by tracking
their encounters, representatives for the states told Reuters on
Thursday.

Virginia last week became the first U.S. state to urge residents to
download such an app using technology developed by smartphone
software giants Apple Inc and Alphabet Inc's Google.
About 316,000 people have downloaded Virginia's app, COVIDWISE, Jeff
Stover, a state health department official, told Reuters during an
online event about pandemic technology hosted by the Massachusetts
Institute of Technology-affiliated Responsible Data Foundation.
North Dakota launched its app, Care19 Alert, on Thursday and Wyoming
will release an app on Friday, , whose company ProudCrowd developed
the apps, also said during the event.
Alabama, which has been testing its GuideSafe app among some
university students and staff, plans to begin marketing it statewide
on Monday, said Sue Feldman, director of graduate programs in health
informatics at University of Alabama at Birmingham.
Washington, which recently tested its CommonCircle app at a
hospital, and Pennsylvania are among other states that could
formally launch apps in the coming weeks with the Apple-Google
technology.

The technology enables phones to exchange Bluetooth signals to keep an anonymous
list of close encounters. A user who becomes infected can anonymously notify
recent contacts to get tested or quarantine.
But developers acknowledge they still face challenges in convincing users that
the tracking and notification systems are private and reliable.
For instance, getting contact tracing apps from different states to communicate
with each other, as users cross borders, is untested with North Dakota's app now
the first and only in the United States to support that functionality.
North Dakota previously released an app, Care19 Diary, to help users remember
their location history for contact tracing.
