Incidence and Prevalence Estimates
- Exact incidence is unknown owing to limited reporting
- Once thought to be rare but may in fact be more common (e.g., viral etiologies)
- Children (age 5–15) more often affected than adults due to prevalence of group A streptococcal (GAS) infections in this age group*
- Noninfectious causes more common than infectious causes in adult population
