Scabies is a contact-contagious skin disease caused by the scabies bug, which is easily spread in families and groups. The onset of the disease begins between the fingers, preferably on the wrist flexion, the anterior edge of the armpit, areola, umbilicus, pubic and inner thighs. The lesions are initially red papules, blisters, pustules and scabies tunnels. Over time due to scratching can be secondary pus infection, eczema-like changes or mossification. In addition, reddish-brown nodular damage can occur in the scrotum, penis and other parts. The disease itches intensely at night and mildly during the day. It often leads to scratching, crusting and hyperpigmentation all over the body.

Patients should pay attention to cleanliness and hygiene in general, and bathe frequently. Normal people should try to avoid contact with patients, wash their hands with soap and water after contact, and go to the hospital in time after suspecting that they have contracted the disease.
