can someone let me know if this is heat rash or chicken pox I don't know how to identify chicken pox?

A. hi dear The telltale sign of chickenpox is a crusty, itchy rash. The rash is red, and it usually starts on the face, neck, or chest before spreading to other areas of the body. The rash starts with fluid filled blisters, which crust over within 4–10 days. If an infant scratches the blisters, they may ooze or become infected.
