The revision came after the Biden administration decided to reduce quarantine periods for infected healthcare workers without symptoms so that they could continue attending to sick people.
Walensky’s comments came amid increasing evidence found by health authorities in recent weeks that exposure or infection related to the new coronavirus Omicron variant seldom leads to serious illness or death.
Data shows that nearly 75% of the US population has received at least one dose of a COVID-19 vaccine, while nearly 62% has had two doses that fulfill the “fully vaccinated” definition.
