Hand, Foot, and Mouth Disease: The Back-to-School Rash Altoona Parents Are Asking About

Between sports physicals, new backpacks, and settling back into routines, the last thing any Altoona-area family wants to see this school season is an unfamiliar rash. Yet as classrooms and daycares fill back up, one of the more common reasons parents reach for our Symptom Checker’s “Rash” category is a viral illness with a distinctive name: hand, foot, and mouth disease. At Pediatric Healthcare Associates, we typically see cases pick up right alongside the return to group settings each fall. 

What Hand, Foot, and Mouth Disease Is 

Despite the alarming name, hand, foot, and mouth disease (HFMD) has nothing to do with the livestock illness “foot-and-mouth disease.” It’s a common, usually mild viral illness caused by coxsackievirus, most often affecting children under five, though older kids and even adults can catch it too. It spreads easily in daycares and elementary schools through close contact, shared toys, and respiratory droplets — exactly the conditions of a busy fall classroom. 

Recognizing the Symptoms 

HFMD typically starts with a few days of fever, reduced appetite, sore throat, and a general feeling of being unwell — symptoms that can look like any other back-to-school bug at first. What sets it apart usually follows a day or two later: 

  • Small, painful sores or blisters inside the mouth, on the tongue, or on the gums ● A flat or slightly raised rash of red spots, sometimes with small blisters, on the palms of the hands and soles of the feet 
  • Similar spots can also appear on the knees, elbows, buttocks, or diaper area in younger children ● Mouth sores can make eating, drinking, and swallowing uncomfortable for a few days 

If you’re unsure whether what you’re seeing fits this pattern, our Symptom Checker is a helpful first stop for quick guidance on rashes and fever together. 

Caring for Your Child at Home 

There’s no specific medication that cures HFMD — like most viral illnesses, it needs to run its course, usually within 7 to 10 days. In the meantime: 

  • Offer cool, soft foods like yogurt, applesauce, or smoothies that are gentle on mouth sores ● Avoid acidic or spicy foods and drinks, which can sting irritated areas 
  • Use children’s acetaminophen or ibuprofen, as directed, for fever or discomfort ● Encourage fluids to prevent dehydration, especially if your child is reluctant to eat or drink because of mouth pain 
  • Keep little ones from scratching skin blisters to reduce the risk of secondary infection

When to Bring Your Child In 

Most cases of HFMD resolve without complications, but it’s worth scheduling a same-day sick visit if your child isn’t drinking enough fluids, has a fever that won’t come down, seems unusually lethargic, or if you simply want confirmation that the rash is HFMD and not something else. Rarely, HFMD can lead to dehydration significant enough to need extra support, so don’t hesitate to reach out if you’re concerned. 

Limiting the Spread at School and Home 

HFMD is most contagious during the first week of illness. Many schools and daycares ask that children stay home while fever is present or until sores have dried up — check with your specific school’s policy. At home, frequent handwashing, avoiding shared cups and utensils, and routinely cleaning shared toys and surfaces all help limit spread to siblings and classmates.
