they recovered from their symptoms about two days ago. i do not have any symptoms. my entire family was there having christmas dinner.

Thanks for quick input.

Ideally, People are contagious for at least 2 days after all stomach flu (viral gastroenteritis) symptoms have completely stopped and they feel perfectly fine.

Though studies have shown that the viruses are present in the stool for two weeks and sometimes longer so a person can be contagious even longer, but this fact doesn't fit in many practical cases.

But practically, Patients are no longer considered contagious if they have not had a fever for 24 hours. If all their symptoms have gone away and there is no blood or mucus in the stools, no fever and no diarrhea and you they have not vomited within 24 hours, then usually they are not contagious.
It is advised that infected person, should wash their hands or use hand sanitizer , this is the most effective way to stop the spread of these viruses to others.

You would be pretty safe, and i would not panic for getting stomach flu.

If you have any further query then please feel free to ask.
