What should you know about spa pool folliculitis?

This condition is an infection or inflammation around hair follicles after exposure to inadequately maintained hot tubs, spas, or pools. Small red bumps or pustules may appear under swimwear, often with itch or tenderness. Wet fabric pressed against the skin can keep the area warm and damp. The timing supports the diagnosis, but other rashes can look similar, so a clinician may need to examine persistent symptoms.

Rinse off after swimming, remove wet clothing promptly, and launder swimwear. Keep the rash clean and dry, avoid shaving and friction, and do not squeeze the spots. Use separate towels and do not return to the spa until the skin has settled. If the rash persists, spreads, or becomes painful, a clinician can decide whether antibiotics for skin infection are appropriate. Avoid leftover or non-prescribed antibiotics.

Seek prompt assessment for fever, chills, rapidly spreading redness, severe pain, pus-filled areas that enlarge, or red streaks. Get advice sooner if you have diabetes, reduced immunity, or a large affected area. Eye, facial, or genital involvement also merits medical review.

Ask whether the rash fits spa pool folliculitis, how to care for it, and what symptoms would indicate a deeper infection. Ask when it is safe to use pools again and how to check water maintenance.
