The Washington State Department of Health reported Wednesday that its COVID-19 exposure notification tool saved an estimated 30-120 lives and likely prevented about 6,000 cases during its first four months while in use.
Researchers at the University of Washington and the DOH released the results on Monday after conducting a modeling study of the tool.
Since Nov. 30, 2020, more than 2 million people have enabled WA Notify since it launched, according to a release.
The tool sends alerts to people who could have been exposed to the virus.
“The goal for exposure notification is to help more people get the information and care they need more quickly so they can avoid spreading COVID-19 to others,” said Lacy Fehrenbach, deputy secretary of COVID-19 Response at DOH.
