How is herpangina diagnosed in a child?

Your child’s healthcare provider can diagnose herpangina with a complete health history and physical exam of your child. The sores look different from other sores and usually easy to identify.

How is herpangina treated in a child?

Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how severe the condition is.

The goal of treatment is to help ease symptoms. Since herpangina is a viral infection, antibiotics won’t work. Treatment may include:

  • Drinking more fluids
  • Taking acetaminophen for any fever
  • Taking oral pain relievers, such as lozenges
  • Eating a bland diet, such as cold milk and ice cream. Your child should stay away from acidic and spicy foods.

Most children with the illness feel better in about a week. It's important that your child drinks enough fluids to prevent getting dehydrated.

Proper handwashing can help prevent the illness from being spread to other children.
