A diaper rash is a skin problem that develops in the area beneath an infant's diaper.
Dermatitis - diaper and Candida; Candida-associated diaper dermatitis; Diaper dermatitis
Causes, incidence, and risk factors
Diaper rashes are common in babies between 4 and 15 months old. They may be noticed more when babies begin to eat solid foods.
Diaper rashes caused by infection with a yeast or fungus called Candida are very common in children. Candida is found everywhere in the environment. It grows best in warm, moist places, such as under a diaper. A yeast-related diaper rash is more likely to occur in babies who:
- Are not kept clean and dry
- Are taking antibiotics, or whose mothers are taking antibiotics while breast feeding
- Have more frequent stools
Other causes of diaper rashes include:
- Acids in the stool (seen more often when the child has diarrhea)
- Ammonia (produced when bacteria break down urine)
- Diapers that are too tight or rub the skin
- Reactions to soaps and other products used to clean cloth diapers
- Too much moisture
