Hand Foot and Mouth Disease (HFMD) is a contagious viral infection that is common in young children, but can also occur in teenagers and adults. It usually causes small red spots or blisters on the hands and feet and painful ulcers inside the mouth. Some also develop a fever, sore throat, loss of appetite or fatigue. Most cases resolve in 7 to 10 days with rest and supportive care. Knowing what the rash looks like, how the infection is spread and when to seek medical help can make it easier to manage symptoms and protect other family members.
What Does Hand Foot and Mouth Disease Look Like in Adults and Children?
The rash of Hand Foot and Mouth Disease usually appears on the palms, soles and sometimes the fingers, toes, buttocks, or legs. You may also notice painful sores on the tongue, gums and inside the cheeks.
The rash starts as red flat spots and may develop into small blisters. Usually, these spots are not very itchy, but they may be uncomfortable or tender. Mouth sores can appear as small red spots, blisters or shallow sores.
Kids may turn down food or drink because it hurts to swallow. Adults can have similar symptoms, but their illness may be mild and some may have few noticeable signs.
HFMD can look different on different people. But a rash by itself cannot be used to confirm the infection, as other viruses and skin conditions can cause similar spots.
What Are the First Symptoms of Hand Foot and Mouth Disease?
The first signs usually show up 3 to 6 days after viral exposure. The characteristic rash may be preceded by sore throat, fever, general malaise and poor appetite.
Early symptoms may include:
- Fever.
- Painful throat.
- Just feeling tired or just not well.
- Loss of appetite.
- Sore mouth or throat.
A day or two after the fever begins, spots on the skin and sores in the mouth may develop. But the order and severity of the symptoms may differ.
A parent may notice blisters on a child’s hands, for example, after the child has developed a fever and refused breakfast. In other instances, pain in the mouth may be the first obvious sign that something is wrong.
Why do adults get hand, foot, and mouth disease?
Adults can get HFMD if they are exposed to saliva, mucus, blister fluid, or stool from an infected person. The infection is caused by enteroviruses, most often Coxsackievirus A16, but other types can cause it.
Parents, childcare workers, teachers, and people looking after sick children may be exposed during routine activities. The virus can be transmitted by changing diapers, sharing eating utensils, cleaning contaminated surfaces, or touching the face after contact with infected material.
Sometimes adults think of HFMD as just a childhood illness. This is a common misconception: Adults can get infected even if they have taken care of children before. Previous infection with a certain virus may not protect them from all types of HFMD.
What Is The Difference Between Hand Foot And Mouth Disease In Adults And Children?
The infection causes similar symptoms in all age groups, but how people experience it can vary. Young children may not be able to tell you about pain in the mouth; adults may have pain in their hands, feet, or throat.
| Feature | Children | Adults |
| Fever | Common | May occur or be mild |
| Mouth sores | Can make eating and drinking difficult | Can make swallowing painful |
| Hand and foot rash | Common | May be mild or more noticeable |
| Tiredness | Common | Common |
| Dehydration risk | Higher if a child refuses fluids | Possible if drinking becomes painful |
The most important thing for both age groups is to ensure enough fluid intake. Babies and young children need to be watched closely because they might not be able to express thirst or dehydration clearly.
How Is Hand, Foot, and Mouth Disease Treated at Home?
There is no particular medicine for Hand Foot and Mouth Disease and antibiotics are ineffective against the viruses that cause it. Treatment is directed to relief of pain, control of fever and prevention of dehydration as the body recovers.
Most people get better in 7 to 10 days. The following steps may help make the illness easier to deal with:
- Drink plenty of fluids: Offer small sips of water or other suitable fluids. Cold drinks can soothe mouth sores.
- Eat soft foods: Yoghurt and other soft, non-acidic foods may be easier to swallow. Avoid spicy, salty or acidic foods if you are sensitive to them.
- Control pain and fever: Discuss with a healthcare professional or pharmacist which medicines are right for you and the appropriate dosage for your age. Do not give aspirin to children.
- Keep skin clean: Do not burst any blisters, and wash your hands after touching the affected skin.
- Give yourself time to recover: When you are sick, stay home and avoid close contact with others while symptoms are active.
If your child refuses fluids because of mouth pain, don’t force feed them. The first thing is to get them rehydrated. If they can’t drink enough, they need to go to a doctor.”
How to Prevent Hand Foot and Mouth Disease from Spreading?
HFMD is easily transmitted via respiratory droplets, saliva, stool, blister fluid, and contaminated surfaces. Good hygiene and minimising close contact can reduce the chances of passing the infection to other people.
To safeguard your home:
- Wash your hands with soap and water for at least 20 seconds, especially after changing diapers or using the toilet.
- Clean and disinfect surfaces, toys, and other things that are touched a lot and shared.
- Do not share cups, cutlery, towels, or other personal belongings.
- Cover your coughs and sneezes. Dispose of tissues properly.
- Do not kiss or have close contact with infected persons.
People may still shed the virus after symptoms have resolved, particularly in stool. Handwashing should continue even after the rash is gone.
When to Contact a Healthcare Professional
Most cases are mild, but some symptoms require medical attention. Call a health care provider if a child or adult cannot drink enough fluids, has a persistent fever, has worsening symptoms, or does not improve within 7 to 10 days.
Call your healthcare provider right away if you develop any of the following signs of dehydration: decreased urination, very dry mouth, or unusual sleepiness. Urgent assessment needed if severe headache with stiff neck, confusion, or difficulty waking Dial emergency services for a life-threatening emergency.
Seek individual medical advice if you are a baby under six months of age, have a weakened immune system, or are pregnant and may have been exposed.
In many cases, a health care provider can diagnose HFMD by looking at the rash and mouth sores and considering the symptoms. If the diagnosis is not clear, testing may be considered.
