First of all, the pathogen of scabies is scabies mite, also known as scabies. Sarcoptes scabies is a kind of human sarcoptes scabies, which parasitizes in the cuticle of epidermis and causes human infection. This kind of mite is so small that it is difficult to find it with the naked eye. Sarcoptes scabies are characterized by photophobia, often dormant during the day and active at night.

Secondly, the etiology of scabies has a certain relationship with infection. There are many ways to get infected with this disease, mainly through intimate contact such as sharing a bed and shaking hands, and indirect contact with contaminated clothes, including bedding, underwear, towels and bath towels. Usually this disease will cause a small-scale epidemic in families and dormitories. Of course, the cause of the disease lies in direct contact with infection.

Finally, the etiology of scabies is closely related to sexual contact infection. In the process of sexual life, close contact with scabies patients will infect scabies. Once infected with scabies, people who do not have good hygiene habits in daily life and have weak immunity are very likely to suffer from scabies.
