PFAPA (periodic fevers with aphthous stomatitis, pharyngitis, and cervical adenitis) syndrome is the most common periodic fever syndrome in children.

PFAPA syndrome typically starts between 2 and 5 years of age and tends to be more common among boys. It has been recognized in adults as well.

Symptoms of PFAPA Syndrome

PFAPA syndrome causes fatigue, chills, and occasionally abdominal pain and headache as well as fever, sore throat, mouth ulcers, and swollen lymph nodes.

About once a month, children have a fever that typically lasts 3 to 6 days.

Children are healthy between episodes, and growth is normal.

Diagnosis of PFAPA Syndrome

  • A doctor's evaluation

A doctor usually bases the diagnosis of PFAPA syndrome on symptoms and the pattern in which they occur.

Blood tests (such as C-reactive protein and erythrocyte sedimentation rate, sometimes called inflammatory markers) may be done to measure inflammation.
