What to Know About Hand, Foot & Mouth Disease (HFMD)
If you’ve ever heard another parent whisper “hand, foot & mouth is going around,” you know to brace yourself. This common viral illness spreads quickly through daycare and preschool and while it sounds alarming, it’s usually more uncomfortable than serious. Here’s the pediatrician-approved guide for what to expect and how to care for your child.
What Is Hand, Foot & Mouth Disease?
Hand, Foot & Mouth Disease is usually caused by the coxsackievirus, and it spreads easily through saliva, mucus, and even stool (yes, diaper changes can be a culprit). Most kids get it before age 5, and while adults can catch it, it’s much more common (and more symptomatic) in young children.
Early Symptoms to Watch For
The first signs can look a lot like a regular virus or teething:
Low-grade fever
Sore throat
Fussiness or trouble sleeping
Drooling (from mouth pain)
Within a day or two, the classic rash starts to show up.
What the Rash Looks Like
The rash of HFMD is pretty distinct:
Painful red spots or blisters on the hands, feet, and inside the mouth
Sometimes on the buttocks or legs, too
Mouth sores can make eating and drinking uncomfortable
It’s not usually itchy, but it is uncomfortable.
How It Spreads (and When Kids Are Contagious)
Kids are most contagious during the first few days of illness — but the virus can stick around in stool for weeks, so good hygiene is key.
Wash hands frequently (especially after diaper changes)
Disinfect shared toys and surfaces
Keep your child home until fever is gone and they feel well enough to eat and drink comfortably
How to Help Your Child Feel Better
There’s no cure, just supportive care:
Hydration is the most important part. If mouth sores are painful, offer cold liquids, smoothies, or popsicles.
Use pain relievers like acetaminophen or ibuprofen as directed for fever or discomfort.
Avoid spicy or acidic foods that can irritate mouth sores.
Lots of cuddles and rest
How Long Does It Last?
Most cases of HFMD clear up in about 7–10 days. Call your pediatrician if:
Your child isn’t drinking well or shows signs of dehydration
Fever lasts more than 3 days
You’re concerned about worsening symptoms
Dr. Alex’s Final Word
HFMD looks dramatic, but it’s usually a mild illness that passes quickly. The key is keeping your child comfortable, hydrated, and home to rest and recover.
