Winter Viruses

U.S. flu infections are showing signs of a slight decline, but health officials say it’s not clear that this severe flu season has peaked. New government data posted Friday covered flu activity through last week. It showed declines in medical office visits due to flu-like illness and in the number of states reporting high flu activity. But flu deaths and hospitalizations rose. By some measures this season is already surpassing the flu epidemic of last winter. That was one of the harshest in recent history. And experts believe there’s more suffering ahead.
