Hot tub folliculitis is caused by bacteria Pseudomonas aeruginosa (P. aeruginosa), it infects the upper part of the hair follicle. This is the same microbe that causes otitis externa or swimmer’s otitis.

These bacteria thrive in warm water, especially poorly maintained recreational water.Longer immersion in contaminated water Pseudomonas, The greater your chances of getting hot tub folliculitis.

Water can appear clear and clean but still contain Pseudomonas germ.

As the name suggests, the most common cause of hot tub folliculitis is that the chlorine or pH levels in the hot tub are not properly maintained. However, there are other potential sources:

  • Whirlpool and treatment pool
  • Swimming pools, especially those used by multiple people
  • a warm lake, river or stream
  • water slide
  • Contaminated inflatable pool toys
  • bath sponge

diagnosis

A healthcare provider should be able to diagnose hot tub folliculitis by looking at it and knowing that the patient has used a hot tub recently. Usually no additional testing is required.

However, if home remedies and your healthcare provider’s care don’t clear the rash, a skin sample may be taken to determine the cause. This can be done by taking a sample of fluid from the blister or by taking a small skin biopsy.examine the sample under the microscope to look for Pseudomonas germ.

These tests can also be ordered if there is any doubt about what is causing the rash. Hot tub folliculitis can look similar to other skin conditions, such as:

  • acne
  • contact dermatitis
  • Other types of folliculitis
  • other types of bacterial infections, such as Staphylococcus aureus
  • insect bites
  • nodular scabies

Talk to your healthcare provider before trying any of the following:

  • Applying a warm, damp washcloth or compress to the infected area several times a day can relieve pain.
  • Over-the-counter itching medications, such as 1% hydrocortisone, can also help relieve discomfort. Ask your healthcare provider or pharmacist for advice.
  • Diluted white vinegar compresses are sometimes recommended because acetic acid (the acid in vinegar) has been shown to kill Pseudomonas. General guidelines call for applying a mixture of half water and half vinegar as a dressing to the affected area for 15 minutes twice a day.

Because the rash is relatively benign and resolves on its own, hot tub folliculitis usually does not require specific treatment.

If home care doesn’t work, or your rash is severe, your healthcare provider may prescribe a topical antimicrobial, such as gentamicin cream or polymyxin B spray. In cases of widespread resistance, the oral antibiotic ciprofloxacin (ciprofloxacin) may be prescribed.

You should call your healthcare provider if:

  • Your rash does not improve after 14 days
  • your rash becomes increasingly painful or spreads
  • you have boils or large lumps
  • pain in your breast tissue or nipples
  • you feel sicker or have a fever

A hot tub folliculitis rash may leave areas of hyperpigmented (darkened) skin after it has fully healed. This should subside over time, but may take up to 18 months. If hyperpigmentation bothers you, talk to your healthcare provider about treatments that can help lighten the discolored areas more quickly.

The U.S. Centers for Disease Control and Prevention recommends testing water at least twice a day.
  • Disinfect or replace loofah and bath bag regularly. You can soak them in a diluted bleach and water mixture for 5 minutes, then rinse thoroughly.
