What could be the cause of an itchy red patch that does not go away after applying moisturizer and antibiotic cream?

Hi,

Your child's rash is very well circumscribed, red and a bit scaly. It appears to be a fungal infection. This is a common rash caused by fungus, and it should respond well to an antifungal cream. Some doctors might prescribe an antifungal - mild steroid cream combination.

You can bring your child to see a doctor or even do a telemedicine E-consult for convenience.
