Pseudomonas whirlpool dermatitis. Report of an outbreak in two families
Abstract:
Pseudomonas aeruginosa skin infections developed in four children and their parents after use of a recreational whirlpool. These patients were carefully followed throughout the course of their illnesses. The incubation period was two to five days. The skin lesions included erythematous macules and papules, pustules, and nodules. The severity of the illness varied from a few scattered pustules in one patient to an extensive truncal rash, malaise, and fever in another patient. P. aeruginosa was recovered from skin lesions and the whirlpool water. Gram stains from two patients revealed polymorphonuclear leukocytes and gram-negative rods. In all patients, the rash improved within seven days and local application of povidone-iodine did not appear beneficial.
Insights
Recreational whirlpool use led to Pseudomonas aeruginosa skin infections in children and parents. Symptoms included a rash, fever, and malaise, with recovery within seven days.
Area of Science:
- Dermatology
- Infectious Diseases
- Public Health
Background:
- Recreational water venues can harbor pathogens.
- Pseudomonas aeruginosa is an opportunistic bacterium.
- Skin infections can arise from contaminated water exposure.
Observation:
- Four children and their parents developed skin infections after using a whirlpool.
- Incubation period ranged from two to five days.
- Lesions varied from macules and papules to pustules and nodules.
Findings:
- Pseudomonas aeruginosa was identified in skin lesions and whirlpool water.
- Gram stains showed polymorphonuclear leukocytes and gram-negative rods.
- Rash resolved within seven days; povidone-iodine showed no benefit.
Implications:
- Highlights risk of Pseudomonas aeruginosa transmission in recreational whirlpools.
- Emphasizes the need for proper water quality monitoring and maintenance.
- Informs clinical management of hot tub folliculitis and related infections.
