Day 7 of my 7 year son having a stomach virus and he is still cramping and now complaining of a headache? How long can this virus last in a child?

Day 7 of my 7 year son having a stomach virus and he is still cramping and now complaining of a headache? How long can this virus last in a child?

Needs evaluation: Your intuition is right a virus shouldn't last this long, and stomach viruses in general come and go quite quickly. The question is if he is overall better or not? The headache could be due to dehydration from volume losses (vomiting/diarrhea). So I would try fluids now--chicken soup, pedialyte etc. DEFINITELY would go back to the docs though for more evaluation. You don't want to miss something. ...Read more

How long can the varicella-zoster virus last on surfaces?

How long can the varicella-zoster virus last on surfaces?

Shingles: We don't generally worry about shingles virus being spread by surfaces. As a rule you can give someone chicken pox if you have shingles so you should not have anyone with a poor immune system touch your shingles rash.
