Overview
Pharyngitis is one of the most common disorders in adults and children, with more than 10 million ambulatories visits per year. Group A streptococcus is by far the most common bacterial cause of acute pharyngitis, accounting for approximately 15 to 30 percent of cases in children and 5 to 10 percent of cases in adults. Peak seasons for a sore throat include late winter and early spring. Transmission of typical viral and Group A streptococcus (GAS) pharyngitis occurs mostly by hand contact with nasal discharge, rather than by oral contact.
Epidemiology
Viruses are the most common causes of pharyngitis and account for 25% to 45% of all cases.[1][2] Group A streptococcus presents in up to 37% of all children presenting with a sore throat to an outpatient clinic or emergency room and 24% of those presenting at younger than 5 years.[3][4][5]
Demographics
Age
- The highest burden of disease is found in children and young adults, with 50% of cases identified between the ages of 5 to 24 years.[6]
- The GAS accounts for 5% to 10% of pharyngitis in adults and 15% to 30% in children.[7]
- Infectious mononucleosis more common in the age group between 15 and 24 years of age.[8]
Gender
Men and women are affected equally by pharyngitis.
Race
The prevalence of pharyngitis does not vary by race.
