Diaper rash is also known as irritant diaper dermatitis or napkin dermatitis. This is a skin rash that occurs as a result of various skin disorders or irritants in the area covered by diaper in a baby. The rashes are normally characterized by redness of skin and scaling of skin. This usually occurs on the convex or exposed surfaces while areas within the skin folds are spared. Treating diaper rash can be fairly straightforward unless the condition is complicated with bacterial or fungal involvement, and it makes the rash spread even to skin fold areas.
The condition is not caused by the diaper itself but by the materials trapped or contained in the diaper i.e. feces and urine.
