The symptoms of a yeast diaper rash include:

 

The bold red rash is contained within a slightly raised border.

 

The rash is still hanging around after two days of diaper rash treatments.

 

Red or scaly areas (for boys on the scrotum and penis, for girls on the labia and vagina)

 

Pimples, blisters, ulcers, or sores filled with pus

 

Satellite lesions, or smaller red patches that blend with the other patches

 

Typically, the rash is only under the diaper and has not spread to other areas.
