Some health officials say they are concerned about a
decline in COVID-19 testing.
The COVID
Tracking Project shows test rates have dipped by a quarter since mid-January.
The CDC says those tests are critical to controlling the
pandemic, even as vaccinations are getting underway.
The agency
points to case numbers that are plateauing and coronavirus variants that are
spreading.
The CDC
now warns against gatherings for this St. Patrick's Day.

can also increase the risk of spreading the virus.
