Hand, Foot, and Mouth Disease: What Every Parent Should Know

A sudden fever, painful mouth sores, and a mysterious rash? It could be hand, foot, and mouth disease. If you have young children, chances are you’ve heard of hand, foot, and mouth disease (HFMD). It’s one of those childhood illnesses that seems to spread through preschools and daycare centers, sometimes before parents even realize what’s going on.

While the name might sound alarming, the good news is that hand, foot, and mouth disease is usually mild, and most children recover within 7 to 10 days. Still, knowing what to look for and how to keep your little one comfortable can make a big difference.

What Is Hand, Foot, and Mouth Disease?

Hand, foot, and mouth disease is a common viral infection that primarily affects infants and children under five, although older children and adults can get it too. It’s caused by several types of enteroviruses, most commonly coxsackieviruses. Despite the name, it has nothing to do with the foot and mouth disease that affects farm animals.

HFMD is especially common during summer and fall, but outbreaks can happen any time of year, particularly in schools and childcare settings.

Signs and Symptoms to Watch For

Symptoms typically appear three to six days after exposure. At first, your child might seem like they’re coming down with a regular cold.

Common symptoms include:

• Fever: Often one of the first signs of infection.
• Sore throat: Your child may complain that swallowing hurts.
• Painful mouth sores: Small red spots or blisters can develop on the tongue, gums, and inside the cheeks.
• Skin rash: Red spots or small blisters may appear on the palms, soles of the feet, buttocks, arms, or legs.
• Loss of appetite: Mouth sores can make eating and drinking uncomfortable.
• Irritability: Younger children may become fussier than usual.

Not every child experiences all these symptoms. Some may only have a rash, while others develop painful mouth sores without obvious spots on their hands or feet.

How Contagious Is Hand, Foot, and Mouth Disease?

Very contagious! HFMD spreads through saliva, respiratory droplets, blister fluid, contaminated surfaces, and contact with an infected person’s stool. That means everyday activities like sharing toys, changing diapers, or touching frequently used surfaces can spread the virus.

Children are typically most contagious during the first week of illness, but they can continue shedding the virus for days or weeks after symptoms disappear.

The best ways to help prevent spreading HFMD include washing hands frequently with soap and water, disinfecting toys and surfaces, avoiding shared cups and utensils, and teaching children to cover their coughs and sneezes.

How Do You Treat Hand, Foot, and Mouth Disease?

Unfortunately, there’s no specific medication that cures HFMD. Since it’s caused by a virus, antibiotics won’t help. The good news? Most cases clear up on their own within seven to ten days. In the meantime, the goal is to keep your child comfortable and hydrated.

Here are a few things that can help:

• Offer cold drinks and popsicles. These can soothe painful mouth sores and encourage hydration.
• Stick to soft foods. Yogurt, applesauce, smoothies, and mashed potatoes are often easier to eat.
• Avoid acidic foods. Orange juice, citrus fruits, and spicy foods can irritate mouth sores.
• Manage discomfort. Age-appropriate acetaminophen or ibuprofen may help with fever and pain. Never give aspirin to children.
• Encourage rest. A little extra downtime can help your child recover.

One of the biggest concerns with HFMD is dehydration. Because mouth sores can make swallowing painful, some children refuse to drink. Watch for fewer wet diapers, decreased urination, dry mouth, or unusual sleepiness.

When Can My Child Return to School or Daycare?

This is probably one of the first questions parents ask, especially when they’re juggling work, school, and childcare. According to the CDC, children can generally return to school or daycare when they:

• No longer have a fever.
• Feel well enough to participate in normal activities.
• Don’t have uncontrolled drooling from mouth sores.

Your child’s school or daycare may have additional requirements, particularly during an outbreak. Keep in mind that the virus can continue spreading even after symptoms improve, so good handwashing remains important.

When Should You Visit Urgent Care?

Most cases of hand, foot, and mouth disease can be managed at home, but sometimes an evaluation is necessary. Consider visiting urgent care if your child has a fever lasting more than three days, symptoms that aren’t improving after ten days, significant mouth pain, or difficulty drinking enough fluids. Children under six months old and those with weakened immune systems should also be evaluated promptly. If your child shows signs of severe dehydration, is difficult to wake, has a seizure, or experiences other severe symptoms, seek emergency medical care.

Hand, foot, and mouth disease can be uncomfortable for children and stressful for parents, especially when painful mouth sores make eating, drinking, and sleeping difficult. Thankfully, most children recover without complications and are back to their normal routines within a week or two.
