Experts worry about how US will see next COVID surge coming

Experts are watching for a potential new COVID-19 surge in the U.S. — and wondering how long it will take to detect

NEW YORK -- As coronavirus infections rise in some parts of the world, experts are watching for a potential new COVID-19 surge in the U.S. — and wondering how long it will take to detect.

Despite disease monitoring improvements over the last two years, they say, some recent developments don't bode well:

—As more people take rapid COVID-19 tests at home, fewer people are getting the gold-standard tests that the government relies on for case counts.

—The Centers for Disease Control and Prevention will soon use fewer labs to look for new variants.
