The earliest and most common symptom of scabies is itching, especially at night. Little red bumps like hives, tiny bites, or pimples appear. In more advanced cases, the skin may be crusty or scaly.
Scabies prefers warmer sites on the skin such as skin folds, where clothing is tight, between the fingers or under the nails, on the elbows or wrists, the buttocks or belt line, around the nipples, and on the penis. Mites also tend to hid in, or on, bracelets and watchbands, or the skin under rings. In children, the infestation may involve the entire body including the palms, soles, and scalp. The child may be tired and irritable because of loss of sleep from itching or scratching all night.
Bacterial infection may occur due to scratching. In many cases, children are treated because of infected skin lesions rather than for the scabies itself. Although treatment of bacterial infections may provide relief, recurrence is almost certain if the scabies infection itself is not treated.
