Hand, foot and mouth disease (HFMD) is a common viral infection that mainly affects babies and young children, although older children can get it too. It’s caused by a group of viruses called enteroviruses, most often the coxsackievirus.
It is not the same as foot and mouth disease, which affects animals and which children cannot catch.
Symptoms usually develop 3-5 days after a child is exposed to the virus and can include:
The rash is typically not itchy but can be sore, especially if blisters form.
HFMD is caused by a viral infection that spreads easily from person to person. It can be passed on through:
Children are most contagious during the first week of illness, but the virus can still be present in their stools for several weeks after symptoms resolve.
There is no specific treatment for Hand, Foot and Mouth, it usually clears on its own within 7-10 days. Care focuses on relieving symptoms and keeping your child comfortable:
Antibiotics are not effective because HFMD is caused by a virus, not bacteria.
At Kidswell Health, our experienced paediatricians can assess your child’s symptoms, confirm the diagnosis, and recommend the most effective ways to keep them comfortable. We can also check for and treat any complications, such as dehydration or secondary infections.
We provide guidance on when it’s safe for your child to return to nursery or school and advice on preventing the spread of HFMD to other family members.

How long does hand, foot and mouth disease last?

How long is hand, foot and mouth disease contagious?
Children are most contagious during the first week of illness, when symptoms are at their peak. However, the virus can still be present in stools for several weeks after recovery. Good handwashing, especially after nappy changes or using the toilet, helps reduce the risk of spreading the infection.
When can my child go back to nursery or school after hand, foot and mouth?
Most children can return once they are feeling well, have no fever, and can comfortably join in daily activities. There’s no need to wait until all blisters have fully healed, but your child should stay home if they are still unwell or unable to participate.
Can adults catch hand, foot and mouth disease from children?
Yes, although it is less common, adults can catch HFMD, especially if they have close contact with an infected child. In adults, symptoms are often milder but can still include fever, sore throat, and rash.
How can I stop hand, foot and mouth disease spreading in my home?
Wash hands regularly with soap and warm water, clean toys and surfaces often, avoid sharing cups, cutlery, or towels, and keep your child home from nursery or school while they have a fever or feel unwell.
