This is turning out to be a very active flu season, but some local experts say it's possible things are starting to peak.

Flu cases have been on the rise nationally, and the latest numbers from Monroe County show about 1350 cases confirmed since the season began in October... and Health Department spokesman John Ricci tells WHAM 1180 News  that's just the reported cases. The actual cases could be a much larger number. He does say officials are hoping we've hit the peak for the current season..

"We have seen a slight dip in the past couple of weeks, we're hoping to see that continue, if for some reason things worsen, then we would make further recommendations."

Dr. John Treanor heads up the Infectious Diseases division at the U of R Medical Center and he's an internationally recognized expert in flu research. He says even though the vaccine this year was supposed to be a good match for the flu strain that's out there, there still have been a significant number of cases...

"The explanation for the apparent lack of protection from the vaccine in some cases isn't because they don't match, it's not clear what it represents."

He says the federal government will likely be doing research on whether there was some specific reason why the flu vaccine was not more effective in some cases.
