NEW YORK (AP) — U.S. flu infections are still surging, and health officials say it’s a severe season that’s likely to get worse. New government data posted Monday shows that by some measures this season is already surpassing the flu epidemic of last winter. That was one of the harshest seasons in recent history. The data was released the same day that the Trump administration said it will no longer recommend flu shots and some other types of vaccines for all children. Forty-five states were reporting high or very high flu activity during the week of Christmas. That’s up from 30 states the week before. A new version of the flu virus — known as the subclade K variant — is accounting for many of the cases.
