What symptom is indicative of scabies in a child?

Scabies is a skin condition caused by an infestation of mites that leads to intense itching and a characteristic rash. In children, one of the hallmark symptoms of scabies is the presence of red, itchy papules, particularly in areas where the mites are likely to burrow, such as the groin, armpits, or between the fingers. These papules are typically small, raised, and can become excoriated due to the itching, leading to redness and inflammation.

The other symptoms listed do not specifically indicate scabies. Fever and cough are more commonly associated with infectious illnesses rather than a skin infestation. A skin rash without itching could suggest other dermatological conditions, but it is not typical for scabies. Skin peeling on the hands can occur due to a variety of conditions, including eczema or contact dermatitis, but does not specifically pertain to scabies. Thus, the red itchy papules in the groin area are the most indicative sign of a scabies infestation in a child.
