PHOENIX (KSAZ) - This flu season has been one of the worst in years, and now, even more bad news for those who have battled the flu: if you've battled the flu once, you're not out of the woods just yet, as you may have to battle the "B" strain of the flu.
Dr. Natasha Bhuyan says she's seeing in her office what some call the "second wave" of flu.
"I've seen patients who said, 'yes, I had flu back in November, wiped out, chills, fatigue, body aches, and now, I'm having same symptoms,'" said Dr. Bhuyan. "It's just not as severe. It can be a total different strain of the flu. People can get the flu twice."
Dr. Bhuyan says influenza "A" strain hit hard at the beginning of flu season.
"That was causing so much illness, it spread really quickly, that's what people were experiencing at the beginning of the year," said Dr. Bhuyan. "Now, we're seeing an uptick in influenza "B", which is mild but it can still make you pretty sick."
Doctors say people should get the flu shot now. It may not have been very effective against influenza "A", but it's doing better against "B".
"What we've seen from other countries is it's relatively effective against influenza "B", so with an increasing number of influenza "B" cases, if you still haven't gotten your shot, now is a really good time because you're much more likely to be protected," said Jessica Rigler with the Arizona Department of Health Services.
