What are pharyngitis and tonsillitis?

Pharyngitis and tonsillitis are infections that cause inflammation and soreness in the throat. When the pharynx, the space between the tonsils and the voice box, is affected, it’s called pharyngitis. When the tonsils are affected it’s called tonsillitis. If your child has inflammation of both the pharynx and the tonsils, it is called pharyngotonsillitis.

These viral or bacterial infections most often occur in the winter and colder months and when your child Is in close contact with other children. Nearly all children will have pharyngitis and tonsillitis at some point during their childhoods.

Pharyngitis and Tonsillitis | Diagnosis & Treatments

How are pharyngitis and tonsillitis diagnosed?

It is often hard to distinguish between a sore throat caused by a virus and one caused by bacteria based on a physical examination, yet it is very important to know if a sore throat is a "strep" throat caused by group A beta-hemolytic streptococci (GABHS). ”Strep” throat requires antibiotic treatment to help prevent the complications associated with these bacteria.

As a result, when children have tonsillitis or pharyngitis symptoms, they receive a strep test and throat culture to determine if the infection is caused by GABHS. This usually involves a throat swab, called a quick test or rapid strep test, in the doctor’s office.

If the quick test or rapid strep test is immediately positive for GABHS, your child will receive antibiotics. If the test is negative, part of the throat swab will be kept for a throat culture. This will further identify if there is any GABHS present. This usually takes two to three days. Your child's doctor will decide the treatment plan based on the findings.

If bacteria are not causing your child’s throat infection, the doctor may screen for viral infection.

How are pharyngitis and tonsillitis treated?

Treatment may include:

  • Acetaminophen and ibuprofen (for pain)
  • Increased fluid intake
  • Throat lozenges
  • Antibiotics (if the cause of the infection is bacterial, not viral)
  • Repeated tonsillitis may require a tonsillectomy or tonsillotomy
