Hot tubs are frequent transfer stations for bacteria. Pseudomonas aeruginosa, a common bacterial infection, is so strongly associated with tubs their main symptom has been dubbed “hot tub rash.” Those afflicted experience inflammation, itching, and pus-filled blisters around hair follicles, particularly on areas of the body that were covered by a swimsuit and hence absorb a lot of hot tub water.
Hot tubes are regularly sampled for bacteria levels and subsequently closed if levels are high and dosing is required to clean it.
