What is the most common cause of diaper rash?

The most common cause of diaper rash is a candidal infection, typically caused by the yeast Candida albicans. This condition often arises when there is prolonged moisture and warmth in the diaper area, creating an ideal environment for yeast to thrive. Factors that contribute to the development of this type of rash include antibiotic use, which can disrupt the normal flora of the skin, and frequent diaper changes that may not adequately prevent moisture accumulation.

Candida-associated diaper dermatitis is characterized by bright red lesions and may be seen with satellite papules, making it distinct from other forms of diaper rash, such as irritant contact dermatitis. Recognizing this common cause is crucial in pediatric care, as effective treatment often involves keeping the area dry, ensuring proper hygiene, and possibly using antifungal creams if a yeast infection is diagnosed. This understanding helps guide appropriate management strategies and reassures parents dealing with this common pediatric issue.
