Scabies is a skin disease caused by scabies (or scabies mite) infection. The scabies mite is parasitic in the skin and digs “tunnels” in which mechanical irritation is produced, and its secretions and excretions cause an allergic reaction, resulting in severe itching of the skin, especially at night (because the scabies mite is more active at night). The disease occurs mostly in winter. Scabies onset sites are mostly seen in skin folds and thin and tender areas (such as finger crevices, wrists, elbow sockets, armpits, under the breast, around the umbilicus, lower abdomen, external genitalia, and inner femur). The main ways of transmission of scabies are direct contact, such as sharing a bed with a patient, shaking hands, holding a sick child, etc., and indirect contact, such as contact with clothes, towels, shoes and socks, bedding, bath towels, etc., contaminated by scabies. Scabies treatment is quite simple, the main external drug, the most commonly used is 10% sulfur ointment (children for 5% sulfur ointment), scabies cream (Lindane cream), Dacronin chlorhexidine sulfur ointment (bacterial scabies ointment), etc., the use of the following: external application of 5% to 10% sulfur ointment every night (the application site from the neck below coated all over the body, including hand crevice, foot, breast under the armpit, the root of the thigh, the anus and The area of the external genitalia should be evenly coated. It should be noted that the parts without rashes should also be applied all over; the parts with rashes should be smoothed more and then massaged repeatedly for a while) for 3 to 5 days. After the 5th day, take a shower. Change to clean clothes and pants. The patient’s changed clothes and pants, sheets and pillowcases should be disinfected by boiling. Items that cannot be boiled, such as bedding, can be disinfected by exposure to the sun. Repeat treatment if a new rash occurs within 1 to 2 weeks after treatment.
