Hot tub folliculitis
Hot tub folliculitis (also known as Pseudomonas aeruginosa folliculitis) is a common type of folliculitis, a condition which causes inflammation of hair follicles.
This condition is caused by an infection of hair follicles due to the bacterium Pseudomonas aeruginosa. The bacterium is commonly found in hot tubs, water slides, and such places. Children are more prone to this because they usually stay in the water longer than adults. 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. The dots usually go away after about 7 to 10 days, but the condition leaves a hyperpigmented lesion that goes away after a few months.
