More than 150 million Americans can get pop-up notifications from local health authorities if they have been exposed to the coronavirus using a phone app.

There are now more than 150 million Americans who could receive pop-up notifications from local health authorities if they have spent time near somebody who has tested positive for COVID-19, but only if more people activate them, writes Geoffrey A. Fowler for The Washington Post.

Pennsylvania’s app was downloaded nearly half a million times in the two months it has been up, and according to state officials, it has been helpful.

“We do believe Bluetooth exposure notification apps are effective,” said Maggi Mumma, deputy press secretary at the state’s Department of Health.

But officials were quick to point out that the more people use the app, the more efficient it will become.
