Scabies is a highly contagious skin infestation caused by the mite Sarcoptes scabiei, which burrows into the upper layer of the skin to lay eggs. The infestation triggers intense itching, especially at night, along with a pimple-like rash, redness, and sometimes small burrow lines on the skin. Commonly affected areas include the hands, wrists, elbows, waist, and genital region. Scabies spreads primarily through prolonged direct skin-to-skin contact with an infested person, and less commonly through contact with contaminated clothing, bedding, or towels. While the infestation is uncomfortable, it is not dangerous in otherwise healthy individuals, though persistent scratching can lead to secondary bacterial infections. Early recognition and treatment help control the spread and relieve symptoms.
