RALEIGH, N.C. (AP) — Six months ago, Apple and Google introduced a new smartphone tool designed to notify people who might have been exposed to the coronavirus, without disclosing any personal information. But for the most part, Americans haven't been all that interested.

Fewer than half of U.S. states and territories — 18 in total — have made such technology widely available. And according to a data analysis by The Associated Press, the vast majority of Americans in such locations haven't activated the tool.
