Health A to Z
Hand, foot and mouth disease is a common infection that causes mouth ulcers and spots on the hands and feet.
It's most common in young children – particularly those under 10 – but can affect older children and adults as well.
Hand, foot and mouth disease can be unpleasant, but it will usually clear up by itself within 7 to 10 days. You can normally look after yourself or your child at home.
The infection is not related to foot and mouth disease, which affects cattle, sheep and pigs.

The symptoms of hand, foot and mouth disease usually develop between three and five days after being exposed to the infection.
The first symptoms may include:
After one or two days, red spots appear on the tongue and inside the mouth.
These quickly develop into larger yellow-grey mouth ulcers with red edges.
The ulcers can be painful and make eating, drinking and swallowing difficult. They should pass within a week.
Soon after the mouth ulcers appear, you'll probably notice a rash made up of small, raised red spots on the skin.
These typically develop on the fingers, the backs or palms of the hand, the soles of the feet, and occasionally on the buttocks and groin.
The spots may then turn into small blisters with a grey centre.
The spots and blisters can sometimes be itchy or uncomfortable and typically last up to 10 days.
If you have hand, foot and mouth disease, the best thing to do is to stay at home until you're feeling better. There's no cure for it, so you have to let it run its course.
