Consequently, a superficial yeast infection and diaper rash can be the same infection in many infants, babies, toddlers, and children.

About 75% of female babies/young girls may develop vaginal yeast infections (vulvovaginal candidiasis).

What are the differences in the causes of yeast infections and diaper rash?

  1. Skin overhydration
  2. Skin maceration
  3. Skin with prolonged contact with urine and feces
  4. Diaper soaps
  5. 3 or more diarrheal stools per day
  6. Biotin deficiency
  7. Contact dermatitis
  8. Allergic reactions

What exams or tests diagnose yeast infections and diaper rash?

Skin scrapings or biopsy material can be cultured or examined with a microscope after potassium hydroxide treatment that reveals the fungi, but is seldom used to diagnose diaper rash. Usually, observing a yeast infection and/or diaper rash is all that is needed.
