Officials say 3 strains of flu circulating in Iowa

DES MOINES, Iowa (AP) — Health officials say there are three strains of influenza currently circulating in Iowa.

The state Department of Public Health says influenza activity in the state remains at a low level, but the three strains mean an individual could become ill with the flu three different times.

The strains include a regular seasonal strain and a 2009 pandemic strain.

Officials say vaccination is the best protection. The flu vaccine covers all three detected strains.

Influenza is a respiratory illness caused by viruses. The department says an average of 300,000 people in Iowa get the flu every year.
