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.
Symptoms of hand, foot and mouth disease
The symptoms of hand, foot and mouth disease usually develop between 3 and 5 days after being exposed to the infection.
The first symptoms may include:
- a high temperature (fever), usually around 38°C to 39°C (100.4-102.2°F)
- a general sense of feeling unwell
- loss of appetite
- coughing
- abdominal (tummy) pain
- a sore throat and mouth
Mouth ulcers
After 1 or 2 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.
Spotty rash and blisters
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.
What to do if you or your child has hand, foot and mouth disease

Hand, foot, and mouth disease is a contagious disease that is caused by different viruses. It usually affects infants and children under 5 years old, occasionally adults will also get the disease. Symptoms of hand, foot, and mouth disease include fever, painful blister-like sores in the mouth, and a rash that may appear as blisters. It is usually a mild disease, and nearly all infected people recover in 7 to 10 days.
Hand, foot, and mouth disease spreads through close personal contact, such as kissing or hugging, coughing and sneezing, contact with feces (poop), and touching objects or surfaces that have the virus on them then putting your fingers in your eyes, nose or mouth.
Viruses that cause hand, foot, and mouth disease occur worldwide and are more common in summer and fall in temperate climates. Large, severe outbreaks affecting thousands of people occur frequently in some countries in Asia.
There is no vaccine to prevent hand, foot, and mouth disease but you can take steps to lower your risk of getting it.

- Cover your mouth and nose with a tissue or your sleeve (not your hands) when coughing or sneezing.
- Try to avoid close contact, such as kissing, hugging, or sharing eating utensils or cups with people who are sick.
