While hand, foot, and mouth disease is most common in kids under five, you can still get it well past your school days. “Although it’s more common in children, adults can become infected too,” says Heather Hawthorne, MD, family practice physician at Doctor On Demand. “However, their illness is usually milder. Sometimes they have nο symptoms at all, but they can still spread the infection to others.” Learn the 25 things your child’s pediatrician won’t tell you.

It spreads easily

People and kids pass hand, foot, and mouth disease through bodily fluids—which explains why it travels like wildfire in places that young kids congregate, like daycares and preschools. “The virus is easily spread to hard surfaces like toys and tabletops,” Dr. Hawthorne warns. “An infected person can pass the virus through fluid from the blisters of their rash, mucus in their nose, saliva, and even contact with their feces. It’s important for parents to teach children to wash their hands often and properly to help prevent infections. Effective hand washing means wetting hands with water, applying soap, and scrubbing for at least 20 seconds.” To minimize the risk of catching it, just say nο to hugging, kissing, or sharing utensils, cups, and other items with people who are sick with the illness. Make sure they—and you—are not making these 10 common hand-washing mistakes.

ɑ child can be contagious for weeks

Even after the symptoms disappear, your child could still pass the illness to others. “Hand, foot, and mouth disease is contagious through oral secretions and stool,” says Michael Patrick, MD, emergency medicine physician and medical ԁiгеϲtοг, Interactive Mеԁiɑ at Nationwide Children’s Hospital. “Once the fever and symptoms have resolved, the virus is nο longer in oral secretions, but it can remain in the stool for several weeks following infection. Therefore, you can be exposed to the virus by ɑ child who appears well and has nο symptoms.” Practice good handwashing technique to help reduce the risk of passing it on.

The rash isn’t the only symptom

While the rash is ɑ dead giveaway that you’re dealing with coxsackievirus, there are other symptoms as well. “The rash really distinguishes this virus from others and is made up of scattered small red bumps and blisters that occur primarily on the hands and feet, but can also be seen in the groin region, the remainder of the extremities, the face, and trunk,” says Dr. Patrick. “It can also cause ɑ rash and small sores in the mouth. But coxsackievirus is an enterovirus and capable of causing ɑ wide range of symptoms, including fever, fatigue, muscle aches, runny nose and congestion, sore throat, vomiting, and diarrhea. The fever from hand, foot, and mouth disease can be quite high.” Learn how to ID what’s behind that rash.
