The holidays have come and gone, and once again Americans are riding a tide of respiratory ailments, including Covid. But so far, this winter’s Covid uptick seems less deadly than last year’s, and much less so than in 2022, when the Omicron surge ground the nation to a halt.

“We’re not seeing the signs that would make me think that we’re heading into another severe wave,” said Caitlin Rivers, an epidemiologist at the Johns Hopkins Center for Health Security. “So far, we’re in relatively good shape.”

Still, there are few masks in sight, and just a fraction of the most vulnerable people have received the latest Covid shots, she noted.

“It’s not too late,” Dr. Rivers added. “We have not even reached peak yet for Covid, and once you reach peak, you still have to get down the other side.” That leaves plenty of time for the vaccine to provide some protection.
