CDC drops quarantine guidelines for contact with COVID-infected person

NEW YORK — The nation’s top public health agency relaxed its COVID-19 guidelines Thursday, dropping the recommendation that Americans quarantine themselves if they come into close contact with an infected person.

The Centers for Disease Control and Prevention also said people no longer need to stay at least 6 feet away from others.

The changes, which come more than 2oe years after the start of the pandemic, are driven by a recognition that an estimated 95% of Americans 16 and older have acquired some level of immunity, either from being vaccinated or infected, agency officials said.

“The current conditions of this pandemic are very different from those of the last two years,” said the CDC’s Greta Massetti, an author of the guidelines.

Many places around the country long ago abandoned social distancing and other once-common precautions, but some of the changes could be particularly important for schools, which resume classes this month in many parts of the country.

Perhaps the biggest education-related change is the end of the recommendation that schools do routine daily testing, although that practice can be reinstated in certain situations during a surge in infections, officials said.

Masks continue to be recommended only in areas where community transmission is deemed high, or if a person is considered at high risk of severe illness.

Also, if you were exposed to COVID-19, take three home tests instead of two to make sure you’re not infected, according to new U.S. recommendations released Thursday.

Previously, the Food and Drug Administration had advised taking two rapid antigen tests over two or three days to rule out infection. But the agency says new studies suggest that protocol can miss too many infections, and could result in people spreading the coronavirus to others, especially if they don’t develop symptoms.
