Sometimes, the local wetness and warmth encourages candidial fungi to grow, so that salves like the one you mention may not work. You should take her to a doctor who will prescribe a local anti-fungal ointment for this problem. Even if there is no itching, do go once and make sure a fungus is not the cause. Once the doctor has certified her as being free from a fungal infection, you may try keeping the area totally dry till the patch heals.

Hello there,

You mentioned the are to be white and inflammed. So I beleive there is some redness as well. Diarrhea can result in secondary lactase deficiency and result in perianal excoriation due to acidic stools. That can be one possibility. If the lesion has developed around the same time as diarrhea then its likely to be excoriation. However if the problem has persisted relatively longer, it can be fungal. So get it seen by a Pediatrician for exact diagnosis for inititation of right treatment.

Take care.
