Recreationally associated Pseudomonas aeruginosa folliculitis. Report of an epidemic

Abstract

An epidemic of P. aeruginosa folliculitis occurred in 117 persons. An indoor swimming pool at a dude ranch was the source of the infection. Recognition of the epidemic occurred through 4 patients who reported to a clinic with a characteristic syndrome of follicular pustular eruptions and associated symptoms. Inadequate disinfection of the water was causative. Many affected persons had prolonged contact with the organism because swimsuits were worn for several hrs after exposure. Early diagnosis and epidemiological investigation were important in treating this disorder.
