Hand, foot and mouth disease is very common in young children, and usually is a mild illness.
It is not related to the serious disease of a similar name that affects cattle, sheep, goats, pigs and other 'cloven-hooved' animals.
Hand, foot and mouth disease is caused by a virus (usually Coxsackie virus A16).
- It causes blisters on the hands, feet, and in the mouth. Blisters can also be in the nappy area of young children.
- Hand, foot and mouth disease can be caused by several other viruses.
- It mostly occurs in warmer weather, and tends to spread easily where a lot of young children are together, such as in a child care setting.
- Once a child has had the infection he or she is not likely to get it again, but because the same rash can be caused by several different viruses it can appear that a child is having the same infection again.
- A child who has the infection may have a fever, be unwilling to eat or drink because of ulcers in the mouth, have a runny nose and sore throat, and not have much energy. The fever can be high, but often is mild.
- Blisters on the hands and feet, and ulcers or blisters in the mouth appear 1-2 days after the first symptoms and may last for 2 – 7 days.
- The blisters often appear in the nappy (genital) area and sometimes also on the upper arms, upper legs and bottoms of children.
- Because of the sore mouth, the child may refuse to take some foods and drinks.
- Most adults will have had the infection in childhood, but if they catch it they will usually have the ulcers in their mouth, but less commonly have the rash.
It takes 3 to 5 days after first being in contact with the virus for the disease to develop.
- A person with the disease is infectious until the blisters dry up. There are viruses in the fluid of the blisters, and they can also be spread by coughing, sneezing and putting objects in the mouth.
- The virus is found in the child's poo, and can still be there for several weeks after the child has recovered. Careful hygiene practices are always needed in child care centres and at home.
- Children with hand foot and mouth disease should not attend school or child care until all the blisters have dried up.
- There is no treatment which will make hand, foot and mouth disease go away more quickly.
- Give paracetamol for fever if needed (see the topic Using paracetamol or ibuprofen).
- Offer plenty of drinks. Avoid drinks like orange juice, which is acidic and can cause pain if the mouth has ulcers. Your child may prefer cold drinks, including cold milk drinks, or ice blocks (these can be made with milk). It does not matter if children do not eat for a day or so if they are having some drinks.
- See your doctor if your child is unwell, or has a bad headache that persists, or a high fever.
- Allow blisters to dry naturally.
- There is no immunisation against hand, foot and mouth disease.
