Some flu measures decline, but it's not clear this severe season has peaked

U.S. flu infections showed signs of a slight decline last week, but health officials say it’s not clear that this severe flu season has peaked.

New government data posted Friday — for flu activity through last week — showed declines in medical office visits due to flu-like illness and in the number of states reporting high flu activity.

However, some measures show this season is already surpassing the flu epidemic of last winter, one of the harshest in recent history. And experts believe there’s more suffering ahead.
