It's almost becoming a game of "whack a mole" when it comes to flu season.

Disease and medical experts say they're able to (in most cases) combat and counter flu strains with vaccines, but that doesn't stop flu from being a threat again this year.

State and other health officials say the flu season this fall and winter could produce higher numbers than last year. The CDC or Centers for Disease Control, considered last year an epidemic. It's estimated some 700,000 people required hospitalization last year.

The peak season is considered December through even March, and officials recommend getting a flu shot. They're readily available at most pharmacies and most are free.

Officials say different flu strains around the world, which are often spread by travelers, are the main culprit for the issues they expect to face this fall and winter.
