CDC data shows nearly 18m people could be living with long Covid even as health agency relaxes isolation recommendations

Some 6.8% of American adults are currently experiencing long Covid symptoms, according to a new survey from the US Centers for Disease Control and Prevention (CDC), revealing an “alarming” increase in recent months even as the health agency relaxes Covid isolation recommendations, experts say.

That means an estimated 17.6 million Americans could now be living with long Covid.

“This should be setting off alarms for many people,” said David Putrino, the Nash Family Director of the Cohen Center for Recovery From Complex Chronic Illness at Mount Sinai. “We’re really starting to see issues emerging faster than I expected.”

When the same survey was conducted in October, 5.3% of respondents were experiencing long Covid symptoms at the time.

The 1.5 percentage-point increase comes after the second-biggest surge of infections across the US this winter, as measured by available wastewater data.
