hot tub folliculitis 

hot tub with undressed chicks

DERMATOLOGY

A dermopathy caused by Pseudomonas aeruginosa, a normal skin inhabitant. When immersed for a prolonged period in hot water, as typically occurs in hot tub parties, P aeruginosa reproduces rapidly and causes an itchy rash which is most prominent on the body regions covered by a bathing suit

Clinical findings Hot tub folliculitis begins hours to days post-ablution with vesiculopustular eruptions over the trunk, buttocks, arms and legs, and may resolve without therapy in a week

Outbreaks of Pseudomonas dermatitis due to hot tub use are preventable if the water is maintained at a pH of 7.2-7.8 with free, residual chlorine levels of 2.0-5.0 mg/L–35; individual susceptibility, immersion time, and concentration of bathers per unit area influence the risk of infection.

Synonyms Hot tub dermatitis, hot tub rash, whirlpool dermatitis
