SIOUX FALLS, S.D. (Dakota News Now) – With the colder weather and more time indoors, families are sharing their love and sharing their germs. If the flu has gone through your family, there is a chance it could make another round.

South Dakota state epidemiologist Dr. Josh Clayton relays what he sees in positive flu cases.

“Influenza peaks typically in February. So I don’t think we’re out of the woods yet.” said Dr. Clayton. “You can have a cough, you can have a sore throat, you might have a little bit of nasal congestion, and a runny nose.”

But there are ways to build a defense.

“Get your flu vaccination and still be protected through the majority of the flu season.” said Dr. Clayton.

The key is frequent hand washing, and rising properly.

Even our kids are taught proper handwashing, but what is best, regular or antibacterial soap?

“More of the traditional soap.” said Dr. Clayton. “Including any soap bubbles and stuff that are on your fingertips or at the wrist. That’s going to be more important than whether it was an antibacterial or a non-antibacterial soap.”

And if you’re grabbing the hand sanitizer…

“Norovirus, which causes nausea, vomiting, and diarrhea in the community, unfortunately, does not work with our alcohol based hand gels.” said Dr. Clayton.

Once your hands are clean, try not to pick up the germs or viruses again.

“Make sure that if you can, you do not touch the doorknob or the handle with your bare hand.” said Dr. Clayton.

Sometimes, getting the flu still happens, but how your body reacts to it determines how hard it could hit.

If you’re 65 and older, CDC and other geriatric organizations suggest talking to your doctor about getting a high-dose flu shot to better protect yourself.
