What can be the cause of general itching in a 6 years old girl for about 2 weeks?

Itchy skin. Is there a rash involved? Does the skin look normal and just itch? A short list: Dry skin (non eczematous), eczema, contact dermatitis/allergy, insect bites….If there is a rash, get your pediatrician to look at it for a diagnosis and treatment if needed.
