The number of people getting the flu this season is on the rise and health experts said it could mean the season is going to see an overall increase compared to previous years.
Thirty-nine states are reporting widespread activity of the flu which means there has been a flu outbreak in at least half the regions in each state.
"The one thing that you could always predict about influenza is that it's unpredictable,” Dr. Anthony Fauci with the National Institute of Allergy and Infectious Diseases said. "It looks like we're on our way to something's that's not going to be light season. How bad it's going to be, we don't know quite yet but it's not going to be an easy season that's for sure."
The flu vaccine is meant to protect against all strains but the strength of the protection can vary.
"It tends to change a bit from season to season which is the reason why we generally have to get vaccinated every year,” Fauci said.
The Centers for Disease Control and Prevention said there have been around 4.6 million flu cases this year.
Around 2,100 people have died from the flu in the U.S. this season.
Fauci said it’s not too late to get the vaccination.
“The benefit of vaccinations is very clear,” Fauci said. “Either it’s going to protect you against infection to begin with or even if you get vaccinated and get infected, it would make it much less likely that you’re going to get serious infection, that you’ll require hospitalization.”
