Scabies is a disease caused by scabies infection and is not a sexually transmitted disease, but is an infectious disease that can be transmitted through sexual intercourse. Scabies prefers a moist, low-temperature environment and is often parasitized on thin, soft skin, such as the flexural side of the limbs, abdomen, fingertips, and groin, and systemic infection is seen in children. The spread of scabies is very strong, and once sex occurs with a scabies patient, the possibility of scabies infection is great. In addition to sexual transmission, scabies can also be transmitted directly through contact with the patient, and indirectly through contact with clothing, sheets, and covers used by the patient. Scabies is characterized by intense itching, which is mild during the day and is evident at night, and is worse after falling asleep. The lesions will show small papules, papules or small pustules, and the diagnosis can generally be clarified by microscopic examination. Once scabies is detected, it needs to be treated promptly with isolation and avoid contact with others as much as possible to avoid widespread sexual transmission. The patient’s changed clothes and the bed sheets and covers that have been touched need to be disinfected by boiling or steam. In addition, the recurrence of scabies is strong, and it is also necessary to pay attention to personal hygiene after healing, to bathe, change clothes, and dry clothes, and to pay attention to the daily ventilation of the room to reduce the triggering factors for scabies infection.
