The county said this year’s flu season has come on quickly and aggressively.

New York Health Commissioner Howard Zucker declared the flu "prevalent" on Thursday.

People who work in health care and are not vaccinated now need to wear surgical masks around patients.

“One thing we’ve learned about influenza is that it’s unpredictable. We try as hard as we can.”

It’s unusual for so many states to still have widespread flu this late into the year, health officials said.
