NEW YORK (AP) — U.S. flu infections surged over the holidays, and health officials are calling it a severe season that is likely to get worse.
New government data posted Monday — for flu activity through the week of Christmas — showed that by some measures this season is already surpassing the flu epidemic of last winter, one of the harshest in recent history.
COVID-19 infections also have been rising, other federal data show, though they remain less common than flu.
Forty-five states were reporting high or very high flu activity during the week of Christmas, up from 30 states the week before.
