Perianal streptococcal infection in Child
Alerts and Notices
Synopsis
It can occur in children with streptococcal pharyngitis, but in healthy children, gastric acid should eliminate most of the swallowed pharyngeal bacteria. Digital contamination from an infected site, such as the pharynx or skin, may be the source. Intrafamilial spread is thought to be due to communal bathing or direct contamination. Diapering by a caregiver with streptococcal pharyngitis or carriage may also cause transfer of the infective organism.
In susceptible patients, perianal streptococcal infection can trigger classic, inverse, or guttate psoriasis. In one report, 11% of patients with perianal streptococcal dermatitis also presented with psoriasis.
