Several H3N2 flu cases reported in Iowa

WATERLOO (KWWL) -

A new flu strain linked to pigs is turning up in Iowa.

The Centers for Disease Control and Prevention says it's seen a total of 18 cases of the H3N2 virus over the last two years.

In Iowa, three central Iowa children were sickened, but they've recovered.

The flu strain also popped up in Pennsylvania, Maine and Indiana.

Officials say this year's vaccine may offer some protection.

H3N2 seems to be mild with only the standard flu symptoms.

Experts say it spreads slowly and is not as threatening as the H1N1 strain that sickened thousands of people back in 2009.
