CDC calls for shorter COVID-19 isolation

U.S. health officials on Monday cut isolation restrictions for Americans who catch the coronavirus from 10 to five days, and similarly shortened the time that close contacts need to quarantine.

Centers for Disease Control and Prevention officials said the guidance is in keeping with growing evidence that people with the coronavirus are most infectious in the two days before and three days after symptoms develop.

The decision also was driven by a recent surge in COVID-19 cases, propelled by the Omicron variant.

Early research suggests Omicron may cause milder illnesses than earlier versions of the coronavirus. But the sheer number of people becoming infected — and therefore having to isolate or quarantine — threatens to crush the ability of hospitals, airlines and other businesses to stay open, experts say.

“Not all of those cases are going to be severe. In fact many are going to be asymptomatic,” CDC Director Rochelle Walensky told The Associated Press on Monday. “We want to make sure there is a mechanism by which we can safely continue to keep society functioning while following the science.”

The change is aimed at people who are not experiencing symptoms. People with symptoms during isolation, or who develop symptoms during quarantine, are encouraged to stay home.

The CDC’s isolation and quarantine guidance has confused the public, and the new recommendations are “happening at a time when more people are testing positive for the first time and looking for guidance,” said Lindsay Wiley, an American University public health law expert.

Nevertheless, the guidance continues to be complex.
