Health officials say they are seeing more of the influenza B strain earlier this flu season, according to an article on the WKBW website.
Strain A usually occurs around late December and early January.
"It is unusual. We are seeing the same thing here at our facilities where many of our patients admitted with influenza this year have actually had influenza B," said Dr. Kevin Shiley, Medical Director of Infection Prevention & Control at Mercy Hospital of Buffalo.
Shiley said they normally wouldn't see this strain until the end of the season, usually around March and April.
