A virus with a simple name that commonly affects young children is making a resurgence in day care centers now that children are returning to day cares fulltime as parents return to work after working remotely during the pandemic.  

Hand, foot and mouth disease is a virus that is common in children under 5 years old, but anyone can get it. The illness is usually not serious, but it is very contagious and can spread quickly at schools and day care centers.

Following guidance from the Centers for Disease Control and Prevention (CDC) and the American Academy of Dermatology (AAD), HSHS St. Joseph’s Hospital Highland and HSHS Medical Group offer the following answers to some of the most frequently-asked-questions about hand, foot and mouth disease.

How does hand, foot and mouth disease spread?
Hand, foot and mouth disease is caused by viruses that belong to the Enterovirus family. A person infected is usually the most contagious during the first week. People can sometimes spread the virus to others for days or weeks after symptoms go away or if they have no symptoms at all.

You can get hand, foot and mouth disease by:

  • Contact with respiratory droplets after a sick person coughs or sneezes.
  • Touching an infected person or making other close contact, like kissing, hugging, or sharing cups or eating utensils.
  • Touching an infected person’s feces, such as changing diapers, then touching your eyes, nose or mouth.
  • Touching objects and surfaces that have the virus on them, like doorknobs or toys, then touching your eyes, nose or mouth.

Matt Wilkinson, MD, pediatrics and internal medicine specialist explained, “The virus can spread quickly through schools and daycares when children frequently put things in their mouths, especially young children who are teething. Children often cough and sneeze without covering their mouths as well. That’s why it’s important to keep children home when they have been exposed to the virus.” 

What are signs my child might have hand, foot and mouth disease?
The symptoms usually include a fever or flu-like symptoms, mouth sores and skin rash commonly found on the hands, mouth and/or feet. Most children have mild symptoms for seven to 10 days, although children younger than 2 years of age may be sick longer as it can take more time for their bodies to get rid of the virus.

Children often get a fever and other flu-like symptoms three to six days after exposure to the virus. You may see signs that they are eating or drinking less, have a sore throat and are generally feeling unwell. One or two days after the fever starts, your child may get painful mouth sores. These sores usually start as small red spots, often in the back of their mouth, that blister and can become painful.

Dr. Wilkinson shared, “Watch for signs that swallowing may be painful for your child since clearly communicating their discomfort can be difficult. They could be drooling more than usual or not eating and drinking.”

The skin rash may also show up on the palms of the hands, soles of the feet, knees, elbows, buttocks or genital area. The rash usually looks like flat, red spots, sometimes with blisters. Fluid in the blister and the resulting scab that forms may also contain the virus. It is important to keep blisters or scabs clean and avoid touching them.

Do I need to take my child to the doctor if I suspect it is hand, foot and mouth disease?
Typically no. Most people get better on their own in seven to 10 days. You can take steps to relieve symptoms and prevent dehydration while you or your child are sick.

Dr. Wilkinson suggested that for children over six months of age, parents may give over-the-counter medications like acetaminophen or ibuprofen (not aspirin) to relieve fever and pain caused by mouth sores. “It is also important to make sure your child drinks enough liquids because mouth sores can make it painful to swallow. So, you want to ensure your child drinks enough to stay hydrated throughout the day.”

You should see your health care provider if:

  • Your child is not drinking enough to stay hydrated.
  • Symptoms do not improve after 10 days.
  • Your child has a weakened immune system.
  • Symptoms are severe.
  • Your child is very young, especially younger than 6 months.

How do I prevent the spread of hand, foot and mouth disease?
Prevention of the spread of this virus is the same as other viruses:

  • Wash your hands frequently and help your children wash frequently.
  • Clean and disinfect frequently touched surfaces and shared items, including toys and doorknobs.
  • Avoid touching your eyes, nose and mouth.
  • Avoid hugging or kissing those with the virus. 
  • Stay home.

Can adults get hand, foot and mouth disease?
Older children and adults can get hand, foot and mouth disease but it is less common. 

Can children get hand, foot and mouth disease more than once?
Yes. Hand, foot and mouth disease is caused by several kinds of viruses, just like there are different flu viruses, so those who have had hand, foot and mouth disease can get it again.

Is this the same disease that is found in animals?
Hand, foot and mouth disease is often confused with foot-and-mouth disease (also called hoof-and-mouth disease), which affects cattle, pigs, sheep and goats. Humans do not get the animal disease, and animals do not get the human disease.
