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. Treatment usually involves prescription creams or lotions that kill the mites. It's important to wash clothing and bedding to prevent re-infestation and protect others from getting scabies.
