Can The Scabies Rash Disappear And Return Within The Same Day?

Can the scabies rash disappear and return within the same day? My child has a red rash, no pustules, which is itchy. It will show up in the morning and then disappear later in the day, only to show up on another part of her body. Usually affected are the back of the neck, stomach, soles of her feet, toes.
