You've heard the sniffles, coughs, and sneezes. Flu season is in full effect in New York.

According to state data, week-over-week lab-confirmed flu cases outside of New York City were up by 75%, rising to 3,603 from 2,058 cases in the previous week.

Because of this, health care workers who haven’t received this year’s flu vaccine have to wear masks in certain work settings.

The state Health Department has recorded more than 23,000 positive flu cases in New York this year. State leaders are urging everyone, not just medical professionals, to get this year’s flu vaccine. 

“The flu strains, like I said, they change every year," said Madalyn Dillabough, a physician assistant for St. Joseph's Health. "So the flu vaccine two years ago wouldn’t really cover you for the flu strains most prevalent this year. So it’s important to, A: To get more antibodies in your system; but B: Make sure the antibodies are targeted at the right strains.” 

State Health Commissioner Dr. James McDonald released a statement on Thursday, saying "I encourage everyone 6 months and older to get the flu shot. It’s not too late to protect yourself and your loved ones and ensure you don’t miss out on holiday celebrations."
