Report: Flu Season in Minnesota Kicking Off With Influenza B

B Strains Have Historically Spread Faster Among Children

MINNEAPOLIS – Flu season in Minnesota is off to an unusual start, with the B strain of influenza causing most of the lab-confirmed cases instead of the usual A strain.

The Star Tribune reports that the Minnesota Department of Health released data Thursday showing that B strains made up about 80% of the positive flu specimens obtained in clinics and hospitals that were tested in the first week of December.

A strains appeared first in the state’s past 10 flu seasons and did most of the damage.

B strains barely registered until February.

The B strains have historically spread faster among children.
