Be aware that hot-tubs and spas have warmer water than pools, so chlorine or other disinfectants break down faster. This leaves hot tubs and spas at risk for the spread of RWIs. Therefore, ask your pool manager about the disinfectant and pH testing program at your hot-tub or pool.

Ensuring frequent testing, control of disinfectant (usually chlorine or bromine) levels, and pH control are likely to prevent the spread of dermatitis.
