Overview
Epidemiology and Demographics
Prevalence
Incidence
- Since 2010, approximately 700 to 1100 cases of necrotizing fasciitis caused by group A streptococcus occur each year in the United states.[1]
- The incidence of necrotizing fasciitis in adults is 0.40 cases per 100,000 people/year and the incidence in children is higher at 0.08 cases per 100,000 people/year.[2][3]
Mortality Rate
- The mortality rate in necrotizing fasciitis is 24%-34%.[4]
- It mainly depends on the time of medical and surgical interventions and extent of spread of infection.
- The mortality rate of necrotizing fasciitis increases from 9% to 63% if associated with mysositis and streptococcal toxic shock syndrome.
- Type 1: Variable, depends on underlying comorbidities
- Type 2: >32% depends on associated myositis or toxic shock
- Type 3: 30- 40%
- Type 4: >47% (higher if immunocompromised)
Age
Necrotizing fasciitis occurs in all age groups but slightly more common among >50 years age.[5]
