TYLER — It's been the most active flu season in almost a decade.
"There have been 150 deaths from children, which is a lot," Dr. Richard Wallace, an infectious disease doctor, said.
While the number of overall flu cases has gone down, a second wave is starting to spread.
Influenza B is especially dangerous in young children and people over 65.
"People of greatest risk, young children, people like me who are over 65, they absolutely must have the vaccine," Dr. Wallace said. Everybody else needs the vaccine, but those are the groups we see the most amounts of deaths and the most amount of complications."
The good news is that unlike Strain A, the flu shot protects well against Strain B.
"If you've not had a flu shot, you still should consider getting a flu shot," Wallace said.
So how do you know if you have the flu?
"You've got fever, you're aching all over, you've got the flu," Wallace said.
Other symptoms include a runny nose, sore throat, coughing and headaches.
If you think you have the flu, Dr. Wallace has some advice you may not have heard before: avoid the clinic at all costs.
"If you think you have the flu, but maybe you don't, the worst place you can go is the clinic, which 25% of the people who are in there coughing and sneezing don't know how to protect themselves in terms of spreading the disease," Wallace said.
Instead, he suggested you go to your local pharmacy within two days of seeing symptoms, and get an anti-viral or anti-influenza medicine.
So the take away: flu season isn't over yet, and it's not too late to start protecting yourself against germs and viruses.
While flu rates are coming down, they're still higher right now than the highest rates last year.
Flu season usually ends around May.
