Scabies is a skin condition caused by tiny mites called Sarcoptes scabiei. These mites burrow into the skin, leading to intense itching and a rash. Scabies is highly contagious and can spread through close physical contact, making it common in crowded living conditions. Symptoms typically include red, itchy bumps and sores, often found in areas like the hands, wrists, and between fingers. Diagnosis is usually made by a healthcare professional through a physical examination. Treatment often involves topical medications that kill the mites and relieve itching, helping to clear the infestation effectively.
