Overview
Pseudomonas dermatitis or hot-tub rash is an infection of the skin. The skin may become itchy and progress to a bumpy red rash that may become tender. There may also be pus-filled blisters that are usually found surrounding hair follicles. Because a swimsuit can keep contaminated water in longer contact with the skin, the rash may be worse under a person’s swimsuit.
Causes
Pseudomonas dermatitis or hot-tub rash is often caused by the bacteria "Pseudomonas aeruginosa". They are commonly found in the environment (water, soil). Most rashes clear up in a few days without medical treatment. However, if your rash persists, consult your healthcare provider. Hot-tub rash is spread by direct skin contact with contaminated water. The rash usually occurs within a few days of swimming in poorly maintained hot tubs or spas but can also be spread by swimming in a contaminated pool or lake.
