Strep Throat in Children: Symptoms, Diagnosis and Treatment for Parents

There are several types of Streptococcus bacteria, or Strep, that can cause infections. Group A Strep typically causes “strep throat,” which can include an infection in the back of the throat and of the tonsils (if present). Other types of Strep include Group B Strep (GBS), an infection in the birth canal for women; Group C Strep, which can also cause a sore throat; and Group D Strep, which causes GI tract infections.

Types of Strep Infections

In addition to a sore throat, Group A Strep can also cause skin infections like impetigo or cellulitis. These infections have the potential to lead to kidney problems. If left untreated, Group A Strep can also lead to rheumatic heart disease or kidney disease.

Symptoms of Strep Throat in Kids

Group A Strep throat typically begins with a sore throat after an incubation period of about three to five days. The full spectrum of symptoms can include:

  • Fever
  • General feeling of being unwell
  • Stomachache (sometimes with vomiting)
  • Headache
  • Rash

Not all children will develop every symptom, and severity can vary from child to child.

Diagnosis and Treatment

Making the diagnosis in the office is simple—it requires a quick swab of the back of the throat. If the test is positive, antibiotics are used to help your child recover. Once a child starts antibiotics, they usually feel better within 24–48 hours. They stop being contagious 24 hours after starting antibiotics, and if they don’t have a fever, they can return to school.

At-Home Care and When to Call

As usual, encourage plenty of fluids for good hydration and make sure your child gets lots of rest. If you’re unsure whether to bring your child into the office or go to the emergency room, our triage nurses are always available to help you decide. Let us know if we can be of help to you!
