NEW YORK (AP) -- Health officials think there's a strong chance this flu season has peaked, but they are watching a recent wave of illnesses from a nastier flu strain.
The Centers for Disease Control and Prevention on Friday gave its latest report on this winter's U.S. flu season.
Flu was reported to be widespread in 48 states last week, down from 49 the week before.
CDC flu forecasters think there's a 90 percent chance the flu season has peaked.
But experts also are eyeing an increase in illnesses from a kind of flu virus that tends to cause more hospitalizations and deaths, especially in the elderly. For the last two weeks, that bug has been seen more than a milder strain that was most common earlier this winter.
