Hot tub folliculitis (pseudomonal folliculitis) is a common type of folliculitis, a condition which causes inflammation of hair follicles.[1]:272

This condition is caused by an infection of hair follicles due to infection by a non-pathogenic strain of the bacterium Pseudomonas aeruginosa. The bacterium is commonly found in hot tubs, water slides, and rarely in swimming pools. Children are more prone because they typically stay in the water longer than adults.[citation needed] Hot tub folliculitis appears on the skin in the form of a rash, roughly resembling chicken pox and then develops further to appear as a pimple. Hot tub folliculitis can be extremely painful and/or itchy, and left alone without scratching will go away much more quickly. If the rash is aggravated, it can stay, worsen, and spread, lasting for months. By that time, it is much more difficult to treat. In an immunocompetent person, the rash is self-limited and will usually resolve after about 7 to 10 days but the condition can leave a hyperpigmented lesion that goes away after a few months.

Normally, the rash does not need specific treatment and will go away on its own.[2] Antibiotics may be prescribed in some cases. If the rash continues to appear longer than the 7- to 10-day time period, a physician should be consulted. Folliculitis that is not treated properly could worsen and cause abscesses.[citation needed]
