Hand, foot, and mouth disease (HFMD) is a common, highly contagious viral illness primarily affecting young children, though it can occur at any age. It causes fever, painful mouth sores, and a blister-like rash on the hands, feet, and buttocks.
Symptoms
Symptoms typically progress through a few stages, usually starting within 3 to 5 days of exposure to the virus:
-
- Early signs: Low fever, sore throat, fatigue, and loss of appetite.
- Mouth sores: Small, painful red spots that turn into ulcers on the tongue, gums, and inner cheeks.
- Skin rash: Non-itchy, blister-like bumps on the palms of the hands and the soles of the feet. They can also appear on the buttocks and genitals.
HFMD is caused by viruses in the Enterovirus family (most commonly the Coxsackievirus). It spreads easily in environments like daycares and schools through:
-
- Direct contact with fluid from blisters or saliva.
- Respiratory droplets from coughing or sneezing.
- The fecal-oral route (unwashed hands and contaminated surfaces).
There is no specific cure or vaccine for HFMD; treatment focuses on managing symptoms and keeping the infected person comfortable:
-
- Fever and pain management: Over-the-counter medications like acetaminophen (Tylenol) or ibuprofen (Motrin/Advil) can be used.
- Preventing dehydration: Encourage drinking plenty of fluids. Cold liquids and soft foods (yogurt, smoothies) are usually preferred as they soothe the throat and mouth.
- Mouth sores: Topical oral anesthetics or numbing gels can be used, but always check with a healthcare provider or pharmacist regarding appropriate age restrictions.

While HFMD rarely causes long-term issues, medical attention should be sought immediately if:
- The infected individual is too dehydrated to drink liquids.
- Symptoms worsen
- There is a very high fever, extreme lethargy, confusion, or seizures.
