Hand, Foot, and Mouth Disease (HFMD) is a contagious viral infection that primarily affects infants and young children under the age of 10. Characterized by sores in the mouth and a rash on the hands and feet, this illness can cause discomfort but is usually mild and self-limiting. However, understanding its symptoms, transmission, and management is crucial to prevent outbreaks and ensure a speedy recovery.
In this detailed guide, we’ll explore everything you need to know about HFMD — from its causes and early warning signs to treatment, recovery, and prevention.
What is Hand, Foot, and Mouth Disease?
Hand, Foot, and Mouth Disease (HFMD) is a viral infection caused by enteroviruses, most commonly the Coxsackievirus A16 and Enterovirus 71. The disease gets its name from the characteristic spots and rashes that appear on the hands, feet, and inside the mouth.
HFMD spreads easily in schools, daycare centers, and among family members — especially during warm and humid weather. While most children recover within a week, adults can also contract the infection, often with milder symptoms.
How Does HFMD Spread?
HFMD is highly contagious and spreads through:
Direct contact with nasal discharge, saliva, or fluid from blisters
Contact with stool from an infected person
Touching contaminated surfaces or objects (like toys, doorknobs, or utensils)
Coughing or sneezing droplets containing the virus
The incubation period — the time between exposure and symptoms — is typically 3 to 7 days.
Children are most contagious during the first week of illness, but the virus can remain in their body for several weeks, meaning they can continue to spread the infection even after recovery.
Common Symptoms of HFMD
The symptoms of Hand, Foot, and Mouth Disease develop gradually and may vary from child to child. The most common signs include:
1. Fever
The first symptom is often a mild to moderate fever, sometimes accompanied by fatigue and irritability.
2. Sore Throat
Children may complain of throat pain and discomfort while swallowing.
3. Mouth Sores
Painful red spots develop inside the mouth — on the tongue, gums, and inner cheeks — which may turn into ulcers. These can make eating and drinking difficult.
4. Rash on Hands and Feet
A red rash or small blisters appear on the palms, soles, and sometimes on the buttocks, knees, or elbows.
5. Loss of Appetite
Due to mouth pain and general malaise, many children eat less during the illness.
6. General Discomfort
Fatigue, irritability, and body aches can accompany the other symptoms.
Most cases are mild and resolve within 7 to 10 days. However, complications can occur if symptoms worsen or if dehydration sets in due to reduced fluid intake.
Causes of HFMD
HFMD is primarily caused by viruses belonging to the Enterovirus group. The most common culprits are:
Coxsackievirus A16 — responsible for most mild cases
Enterovirus 71 (EV71) — linked to severe cases and neurological complications
Other strains like Coxsackievirus A6 can also trigger more intense rashes and symptoms.
The virus can survive on surfaces for several days, making hygiene and sanitation extremely important to prevent its spread.
Who Is Most at Risk?
While anyone can get HFMD, certain groups are more vulnerable:
Children under 10 years old (especially preschoolers)
Daycare attendees where the infection spreads easily
Parents and caregivers in close contact with infected children
People with weakened immune systems
Once a person recovers, they usually develop immunity to the specific virus strain that caused the illness — but reinfection with a different strain is possible.
Diagnosis of Hand, Foot, and Mouth Disease
HFMD is usually diagnosed based on visible symptoms. At Sparsh Diagnostic Centre, your healthcare provider may:
Examine the mouth, hands, and feet for characteristic rashes
Review medical history and recent exposure
In rare cases, take a throat swab or stool sample to confirm the virus
Laboratory confirmation is only necessary in severe or unusual cases, especially if neurological symptoms appear.
Treatment and Home Care
There is no specific antiviral treatment for HFMD. The focus is on relieving symptoms and preventing dehydration. Here are some helpful steps for care and recovery:
1. Stay Hydrated
Encourage plenty of fluids such as water, coconut water, or soup to prevent dehydration.
2. Soothe Mouth Pain
Offer soft, cool foods like yogurt, smoothies, and ice cream. Avoid spicy, salty, or acidic foods that irritate sores.
3. Manage Fever and Pain
Use over-the-counter medications like acetaminophen or ibuprofen (only after consulting a doctor) to reduce fever and discomfort.
4. Maintain Good Hygiene
Regularly wash hands, disinfect toys and surfaces, and avoid sharing utensils or towels.
5. Rest and Monitor Symptoms
Allow the child plenty of rest. If symptoms worsen, contact a doctor immediately.
When to Seek Medical Help
While HFMD usually resolves on its own, seek medical attention if:
Symptoms don’t improve after a few days
Your child has high fever or persistent irritability
They show signs of dehydration (dry mouth, fewer wet diapers)
There is difficulty swallowing or breathing
The rash spreads unusually or becomes painful
Prompt care ensures faster recovery and rule out other serious infections.
Prevention: How to Stop HFMD from Spreading
Because HFMD is contagious, prevention focuses on hygiene and limiting exposure. Here are key preventive tips:
1. Hand Hygiene
Wash hands with soap and water frequently — especially after diaper changes or using the toilet.
2. Disinfect Surfaces
Clean and disinfect toys, tables, and doorknobs regularly.
3. Avoid Close Contact
Keep infected children away from school or daycare until blisters dry up and fever subsides.
4. Cover Coughs and Sneezes
Use tissues or elbows when sneezing and discard tissues properly.
5. Personal Hygiene
Avoid sharing eating utensils, water bottles, towels, or clothing.
6. Strengthen Immunity
Encourage a balanced diet, adequate sleep, and outdoor play for better immune health.
Complications (Rare but Possible)
Although rare, severe HFMD caused by Enterovirus 71 can lead to complications such as:
Viral meningitis – inflammation of the brain and spinal cord membranes
Encephalitis – inflammation of the brain
Polio-like paralysis – extremely rare
Nail loss (temporary) – sometimes occurs weeks after infection
Seek immediate medical attention if your child experiences headache, stiff neck, or persistent vomiting.

Frequently Asked Questions (FAQs)
1. Is Hand, Foot, and Mouth Disease the same as Foot and Mouth Disease in animals?
No. HFMD in humans is caused by different viruses and does not spread from animals to humans.
2. Can adults get HFMD?
Yes, although it’s less common. Adults usually experience milder symptoms than children.
3. How long does HFMD last?
Most cases resolve within 7–10 days without complications.
4. Is HFMD contagious?
Yes. The disease spreads easily through close contact and contaminated surfaces, especially during the first week.
5. Can a child go to school with HFMD?
No. Children should stay home until all blisters have healed and fever has gone to prevent spreading the infection.
6. What foods are safe during HFMD?
Soft, bland foods like mashed potatoes, porridge, smoothies, yogurt, and soups are ideal to reduce discomfort from mouth sores.
7. Can HFMD occur more than once?
Yes. Immunity develops against a specific virus strain, so reinfection with another strain is possible.
8. How can I reduce the risk of HFMD at home?
Practice good hygiene, disinfect commonly touched objects, and encourage frequent handwashing.
Key Takeaway
Hand, Foot, and Mouth Disease may sound alarming, but it’s a self-limiting and manageable illness with proper care. The key lies in maintaining good hygiene, staying hydrated, and monitoring symptoms closely. With prompt care and support, your child can recover comfortably at home within days.
