This isn't the news we want to report as we head into thanksgiving.

But we do want to give you a heads up about a nasty stomach virus that's making the rounds this week in both kids and adults.

Here's what we know, from the folks with EmergiCare of Colorado Springs. Take a look at the symptoms of gastroenteritis.

You’ll notice nausea, vomiting, abdominal cramps, watery diarrhea , muscle aches, headache and sometimes low grade fever.

But here's when to seek medical attention: if you notice any symptoms of dehydration (like thirst or little to no urine production), if you feel weak and dizzy or light-headed, if your fever gets high, or you have abdominal swelling. If you experience any of these symptoms, it's time to be seen.

According to the doctors at EmergiCare, the symptoms usually last up to 48-hours, but they can go on for ten days.

So here's the key, especially as everyone heads to grandma's. You've got to wash your hands, so you're spreading holiday cheer and not the stomach virus.
