A child presents with intense itching and small erythematous papules that appear as lines on the skin, after visiting a crowded daycare.What is the likely diagnosis?

Choice A rationaleImpetigo is a bacterial skin infection characterized by honey-crusted sores, often around the nose and mouth. While it can cause itching, the linear arrangement of papules is not typical of impetigo.Choice B rationaleTinea capitis is a fungal infection of the scalp, causing scaly, itchy patches and potential hair loss. It does not typically present as linear papules on the skin.Choice C rationaleScabies is an infestation caused by the Sarcoptes scabiei mite, which burrows under the skin, laying eggs and causing intense itching, often worse at night. The characteristic lesions are small, erythematous papules that frequently appear in linear patterns due to the mite burrowing. Close contact in crowded environments like daycare facilitates transmission.Choice D rationaleCellulitis is a bacterial infection of the deeper layers of the skin and subcutaneous tissue, characterized by redness, warmth, swelling, and pain. It does not typically present as small, linear papules. .
