TULSA, Oklahoma - A virus has been making the rounds – knocking out people three days at a time.

Dr. Barbara Miller is a physician at the OU Family Medicine Center and says the stomach bug currently out there is a doozy – with symptoms that range from patient to patient.

“Fever, chills can happen, not everyone will get a fever with these things,” Miller said. “Nausea, vomiting, certainly , diarrhea, abdominal cramping."

Doctors say more and more patients are coming in, complaining of stomach illness.

“Most of the time I'm not sure there's a real rhyme or reason an epidemic starts, we tend to see a lot more of infectious illnesses in January, February, and March,” Tipton said.

And the bug gets around quickly.

Miller recommends all the typical safeguards to prevent the virus -- like washing your hands and avoiding sick people.

However, if you already have the bug--she says there's not a lot you can do, other than getting rest and treating your symptoms, with the exception of one.

“Most experts recommend staying away from medicines to stop diarrhea,” the problem is, is that, that's one of the ways our body flushes that virus or toxin or whatever it is out of your system."

And the most important thing, she says, if you're sick -- stay home.
