Hot tub folliculitis is an infection of the skin around the lower part of the hair shaft (hair follicles). It occurs when you come into contact with certain bacteria that live in warm, wet areas.
Causes, incidence, and risk factors
Hot tub folliculitis is caused by the bacteria Pseudomonas aeruginosa. This form of bacteria survives in hot tubs, especially tubs made of wood. Controlling the acid and chlorine level in the water can limit the growth of the bacteria.
The first symptom of hot tub folliculitis is an itchy, bumpy, red rash. Symptoms can appear from several hours to 2 days after contact with the bacteria.
Call your health care provider if you develop symptoms of hot tub folliculitis.
Controlling the acid levels and chlorine content of the hot tub may help prevent the problem.
