How is it different from chickenpox?
Location and itch. Hand, foot and mouth concentrates on the palms, soles, nappy area and mouth, and is sore rather than itchy.
Chickenpox spreads everywhere including the scalp, itches intensely, and shows spots at several stages at once.
Do they need to stay off nursery?
No formal exclusion is required. They can go back once well enough to join in, even with spots remaining.
Keeping a well child home until the last spot fades achieves nothing — the virus is shed for weeks either way.
Is there any treatment?
No, and be wary of anyone who says otherwise. It is viral and self-limiting.
Everything useful is about comfort and fluids, which is genuinely the treatment rather than a consolation prize.
They will not drink. What do I do?
Give pain relief about half an hour before offering drinks, and use cold things — ice lollies, ice cream, cold milk.
Small amounts frequently. If they still refuse everything, or have not passed urine for eight hours, get them seen.
Can adults catch it?
Yes, and adults often have it worse. Mouth ulcers in an adult after a child in the house has had it are a common story.
Their nails are falling off weeks later. Is that related?
Yes, and it is harmless. Nail shedding a few weeks after the illness is well recognised.
The nails grow back normally and nothing needs doing — though almost no one is warned it may happen.
Can they get it more than once?
Yes. Several different viruses cause it, so immunity to one does not prevent the others.
I am pregnant and my child has it. Should I worry?
The risk is generally considered low, and routine exclusion of pregnant women is not advised.
Do mention it, particularly near your due date — and make sure it is not chickenpox, which is a different matter entirely.
Is it related to foot and mouth in animals?
No, not at all. Completely different viruses, completely different species.
The similar name causes regular and unnecessary alarm.
