Hot tub folliculitis is an itchy skin rash that develops due to an infection of hair follicles caused by the bacteria, Pseudomonas aeruginosa. This organism thrives in warm moist environments, hence, its occurrence in hot tubs (usually wood). It may also infect diving suits and natural or synthetic sponges. The bacteria can be controlled by proper chlorination and ph control of the water.
The rash typically develops within hours to 2 days after exposure and often looks like acne with red bumps and pus pimples present on the trunk. Fortunately, it is self limited and generally clears spontaneously without scarring in 7-10 days. Treatment is directed toward symptomatic relief with topical cortisone creams and oral antihistamines. Occasionally, oral antibiotic treatment may be required.
