A message from daycare says something is going around. By dinnertime, your toddler feels warm and pushes away the cup they usually drain in seconds. The next morning, you see tiny spots on their palms.
That’s often how hand, foot, and mouth disease, or HFMD, presents. It’s a common viral illness in young children that causes fever, mouth sores, and a rash. The spots can look alarming. Typically, most children recover within seven to 10 days with supportive care and comfort. The real challenge is keeping your child drinking, because sore mouths and sippy cups aren’t the best of friends.
What Causes HFMD and How It Spreads
HFMD is caused by a group of viruses called enteroviruses and affects mainly kids under 5 years of age, though it can affect older children and adults too. Though outbreaks are known to occur year-round, it typically occurs in late summer and early fall, around the time schools reopen. The virus passes through saliva, stool, blister fluid, and shared cups and toys. Children are most contagious during the first week of the illness. Still, the virus can linger in their stool for several weeks after they recover, and it can be spread even by those who are infected but asymptomatic. That makes handwashing and disinfecting surfaces like toys and diaper changing tables key.
What Symptoms Should You Expect?
There can be different versions of this. Watch for these HFMD symptoms:
- Fever (often the first sign)
- Sore throat and reduced interest in food
- Tiredness, fussiness, or clinginess
- Painful sores on the tongue, gums, inner cheeks, or roof of the mouth
- A reddish rash or small blisters on hands, feet, and mouth
In young children, the clues are behavioral: extra drooling, turning away from favorite foods, crying partway through a bottle.
The rash is typically non-itchy and can be found on any or all of the below areas:
- More commonly on the palms, fingers, soles, toes, and around the mouth
- Less commonly on the legs, arms, buttocks, and genitals
- Rarely even on the chest, back, or abdomen
On darker skin tones, feeling for raised bumps, rough patches, or texture changes rather than looking for a red rash is often more helpful.

How Do You Help Your Child Feel Better?
Because a virus causes it, antibiotics play no role, as they do not work against viruses.
The virus runs its course, and symptoms usually last anywhere between two and five days, except for the rash, which can linger up to 10 days.
Treatment centers around controlling the fever, ensuring hydration, and providing comfort:
- Acetaminophen or ibuprofen as needed to help with fever and mouth pain
- A soft diet, especially cold options like popsicles and ice cream
- Water
- Milk
- Oral rehydration solution like Pedialyte, or a sports drink like Gatorade
- Ice pops
- Smoothies
- Yogurt
Skip anything acidic, spicy, or hot for a few days. And if your child isn’t eating much? That’s okay for now. Fluids matter far more than solids, and a few sips every 15 to 20 minutes is more realistic than finishing a whole cup in one go.
Leave blisters alone and continue regular baths. Keep up good handwashing with soap and water.
There’s one more thing worth knowing before it catches you off guard, well after your child seems better.
“I like to educate parents about the possibility of mild skin peeling or nail changes, even shedding, that can sometimes occur a few weeks to a few months after the initial HFMD illness. It is uncommon and recovers fully, but it is nonetheless disturbing for parents, and they always appreciate a heads-up.”
— Dr. Tejasi Gholap, Pediatrician with Duly Health and Care
If you do notice peeling skin or a nail that ridges, loosens, or falls off, it usually doesn’t require treatment. The nail grows back on its own.
When Should You Call a Doctor?
When swallowing hurts, kids stop drinking, so dehydration can set in. Call your pediatrician if you notice fewer wet diapers, dark urine, a dry mouth, or no tears when crying.
Reach out too if the fever is high and not coming down despite fever medication, or if symptoms aren’t improving after five days. The same goes if your baby is very young, or you aren’t sure it’s HFMD.
Seek emergency care for difficulty breathing, seizures, confusion, excessive sleepiness, trouble waking, or a stiff neck with headache. Serious complications are rare, but they warrant immediate medical attention.
If your pediatric office has no availability or if symptoms seem more serious, find a Duly Immediate Care Center. >
Frequently Asked Questions
When can my child go back to daycare or school? Most children can return once they’re fever-free without medication, feel well enough for normal activities, and aren’t drooling uncontrollably from mouth sores or dealing with multiple open blisters. The rash doesn’t have to be completely gone, though your school or childcare center may have its own policy, so it’s worth a quick phone call to check ahead of their return. If you need a doctor’s note, schedule an appointment with your Duly pediatrician. >
Do antibiotics treat hand, foot and mouth disease? No. A virus causes HFMD, so that antibiotics won’t help. They only come into play if your child develops a secondary bacterial infection on top of the HFMD, which does happen, though rarely. See your pediatrician if symptoms do not start to improve in about five days.
Can adults catch HFMD from their kids? Yes. Parents, teachers, and childcare workers can all pick it up, though adults often have mild symptoms or even no symptoms at all.
Can children get HFMD more than once? Yes. Several different strains of enteroviruses can cause it, so one round doesn’t protect your child from all the different strains. Most kids recover with rest, fluids, supportive care, and comfort. If your child won’t drink or something doesn’t seem right, find a Duly pediatric provider near you. >
