Yes - when my daughter was about a year old she got it at nursery. Pretty sure the doctor just prescribed some cream. It's rarely passed onto adults but I did manage to catch it also :-/ just resulted in blistery feet and fingers for a couple of weeks. There are plenty worse illnesses she could've gotten.
Yes my third child had that he caught it from his cousin I had to take him to the hospital nd that's when they told me wat it was nd it do take up to a month for it to go away the doctor's gave me antibiotic for it.
Yes there was an outbreak at my son's daycare. It lasted 8 days and the scars from the blisters took 1 month to completely fade. It's awful, but it has been going around this summer from what my doctor said.
No but it usually clears up by itself in a week to ten days. But I would still take your child to the doctors of you suspect that you child has it.
