Hand, Foot, and Mouth Disease (HFMD) is a common viral infection affecting mainly infants and children under five. Although it is generally mild and self-limiting, the disease can be uncomfortable for children and concerning for parents. Understanding this condition, including its signs, treatments, and preventive measures, can help parents manage HFMD effectively.
What is Hand, Foot and Mouth Disease?
Hand, foot, and mouth disease is a viral infection typically seen in young children but also affecting older children and adults. It’s characterised by distinctive symptoms including fever, painful mouth ulcers, and a blister-like rash on the hands, feet and sometimes buttocks. While unpleasant, HFMD usually resolves without long-term effects.
Causes of HFMD
HFMD is primarily caused by enteroviruses, notably Coxsackievirus A16 and Enterovirus 71. These viruses thrive in environments such as nurseries, schools and play centres due to frequent close contact among children. Both viruses belong to the Enterovirus family.
How Does HFMD Spread?
HFMD is extremely contagious and commonly spreads through:
- Saliva and nasal mucus (coughing, sneezing, kissing).
- Blister fluid from the skin or mouth ulcers.
- Touching contaminated surfaces, such as toys or tables.
- Faecal-oral route, particularly common when changing nappies or in poor hygiene settings.
Good hygiene practices significantly reduce transmission.

Recognising the Symptoms of HFMD
Symptoms usually appear three to seven days after exposure to the virus. The initial signs often mimic a mild flu or common cold, but distinct symptoms soon follow.
Key symptoms include:
- Fever: Usually mild to moderate, often lasting one to three days.
- Sore throat: Leading to difficulty swallowing.
- Mouth ulcers: Painful red sores in the mouth, making eating and drinking uncomfortable.
- Skin rash: Small red spots or blisters primarily on the palms of the hands, soles of the feet, and occasionally on buttocks.
- Reduced appetite: Often caused by mouth discomfort and sore throat.
- Fatigue and irritability: Children typically become lethargic and uncomfortable.
In rare cases, infected individuals may exhibit few symptoms, making it harder to control outbreaks. These symptoms usually last for 7-10 days.
How Is HFMD Diagnosed?
Doctors typically diagnose HFMD based on visual symptoms and patient history. Laboratory tests are rarely required, but your healthcare provider might recommend additional tests if complications are suspected.
Diagnosis typically involves:
- Physical examination of rash, blisters, and mouth sores by a healthcare provider.
- Reviewing symptoms such as fever and sore throat.
- Laboratory testing (rarely necessary), including swabs or blood tests, to confirm specific viral strains in unusual or complicated cases.
Most doctors diagnose HFMD based on clinical symptoms alone.
Treating HFMD: Managing Symptoms
No antiviral medication specifically targets HFMD, so care focuses on symptom relief and supportive management. Recommended management includes:
- Pain relief medication: Paracetamol or ibuprofen, used responsibly and within recommended dosage guidelines, can relieve fever and pain.
- Hydration: Offer frequent, small sips of water, diluted fruit juice, or oral rehydration solutions to prevent dehydration.
- Dietary modifications: Soft foods (yoghurt, soups, smoothies, mashed potatoes) help minimise mouth pain.
- Mouth Care: Gentle saltwater rinses or topical gels can help relieve discomfort from oral ulcers.
- Rest: Encouraging plenty of rest supports recovery and comfort.
- Isolation: Keeping children at home reduces the spread of the infection to others.
Note: Antibiotics have no effect on viral infections like HFMD and should not be used. Avoid giving aspirin to children due to risk of serious complications.
Possible Complications of HFMD
While HFMD is typically mild, there are rare but significant complications, including:
- Dehydration: Difficulty drinking fluids due to painful mouth ulcers may lead to dehydration.
- Viral meningitis: Inflammation of the membranes around the brain, causing severe headaches, stiff neck, or sensitivity to light.
- Encephalitis: Rare inflammation of the brain that can cause confusion, seizures, or other neurological symptoms.
- Temporary nail loss: Fingernails or toenails may shed weeks after infection, although this is harmless and grows back normally.
Seek immediate medical care if these complications are suspected.
Preventing Hand, Foot, and Mouth Disease
While no vaccine exists for HFMD, good hygiene is essential:
- Handwashing: Regularly washing hands with soap and water for at least 20 seconds.
- Sanitising surfaces: Regularly disinfect toys, tables, and commonly touched areas.
- Avoiding close contact: Limit sharing of utensils, cups, or towels, especially during outbreaks.
- Education: Teach children about basic hygiene practices, such as covering coughs and sneezes.
Currently, there is no available vaccine against HFMD.
When to Seek Medical Attention
You should consult your GP or healthcare professional promptly if:
- Symptoms persist beyond 10 days.
- Your child refuses fluids or becomes dehydrated.
- Symptoms worsen significantly, or new symptoms such as persistent vomiting, severe headache, confusion, or convulsions develop.
Prevention Tips for Parents
- Handwashing: Frequent and thorough handwashing for at least 20 seconds is highly effective.
- Sanitisation: Regularly disinfect toys, surfaces, and commonly handled items.
- Isolation Practices: Keep affected children away from school, nursery, or social settings until they have fully recovered.
FAQs About Hand, Foot, and Mouth Disease (HFMD)
Can adults contract HFMD?
Yes. Adults can contract HFMD but usually experience milder symptoms than children.
Can you catch HFMD more than once?
Yes. Immunity develops only against the specific virus that caused the infection, but different strains can cause repeat infections.
Is HFMD dangerous during pregnancy?
HFMD is generally mild and poses minimal risk to pregnancy, but pregnant women should avoid exposure and discuss any symptoms with their GP or midwife.
How long is HFMD contagious?
HFMD is most contagious during the first week but can remain in faeces for weeks afterwards.
Can my child go to nursery if they have HFMD?
Children should stay home until fever resolves and blisters begin to heal, usually around 7-10 days after onset.
Does HFMD affect adults differently?
Adults usually experience milder symptoms but can still become quite unwell. Hygiene measures should still be practised to prevent spreading.
What foods are best for children with HFMD?
Soft, bland, and cold foods like yoghurt, smoothies, and ice lollies help soothe sore mouths.
