Symptoms and spread
It usually starts with fever and a sore throat, then painful sores in the mouth and a red, sometimes blistery rash on the palms, soles, and diaper area. The biggest problem for parents is that kids refuse to eat or drink because swallowing hurts. The virus spreads through saliva, nasal mucus, blister fluid, and stool, and can stay in stool for weeks after symptoms fade.
Treatment, daycare, prevention
There's no specific antiviral; fever reducers and plenty of fluids get most kids through it in 7–10 days. Call a doctor for fewer wet diapers, unusual sleepiness, a persistent high fever, or any seizure or jerky movements. Policies vary, but many daycares ask kids to stay home until they're fever-free and mouth sores are healing. Washing hands with soap after diaper changes is the best prevention. For dehydration tips, see gastroenteritis.

- Yes, though less often and usually mildly, often caught from a sick child.
- Can you get it twice?
- Yes. Several different viruses cause it, so immunity to one doesn't protect against the others.
