Understanding Hand-Foot-and-Mouth Disease and Herpangina in Children
Hand-Foot-and-Mouth Disease and herpangina are common childhood viral illnesses seen most often during the summer and fall months. These infections are usually mild but can be uncomfortable, especially for young children and infants.
What Is Herpangina?
Herpangina is a viral illness caused by the Coxsackie A virus. Older children often experience a sudden, severe sore throat, while infants may develop high fevers and become irritable. The virus spreads easily, particularly in childcare and school settings.
Common Symptoms
Symptoms typically appear suddenly and may include:
- Fever lasting two to four days
- Headache
- Sore throat
- Abdominal pain
- Occasional vomiting
One of the most noticeable signs of herpangina is the presence of small, gray-colored blisters on the back of the throat and soft palate.
Treatment and Care
The illness usually lasts about one week, and there is no specific medical treatment to cure the virus. Care focuses on relieving symptoms and preventing dehydration. Recommended supportive care includes:
- Acetaminophen (Tylenol) or ibuprofen for pain and fever
- Encouraging frequent fluid intake
- Rest and comfort measures
About 20 percent of children with herpangina may also develop blisters or a rash on the palms of the hands and soles of the feet. This presentation is known as Hand-Foot-and-Mouth Disease. Treatment remains the same and focuses on symptom relief and hydration.
When to Contact a Healthcare Provider
Although these illnesses are very contagious, most adults have developed antibodies over time. In children, the biggest concern is dehydration. Please contact your healthcare provider if your child is having difficulty recovering, is not drinking enough fluids, or shows signs of dehydration.
