How is it caused when scabies occurs frequently?

Frequent scabies outbreaks are the result of multiple factors acting together, including infection with scabies mites, high contagiousness, poor personal hygiene habits, and low immunity. 1. Scabies mite infection: Scabies is mainly caused by infection with scabies mites. These tiny parasites move between the skin surface and the stratum corneum, causing skin lesions and severe itching. 2. High contagiousion: Scabies is highly contagious and easily spreads among people through close contact, sharing clothing or bedding, etc., especially common in schools, dormitories, and other crowded places. 3. Poor personal hygiene habits: Neglecting personal hygiene, such as infrequent bathing and not changing clothes regularly, creates conditions for scabies mites to breed, thus increasing the risk of scabies. 4. Low immunity: When the body's immunity is reduced, it becomes more susceptible to scabies mite infection, which can trigger scabies.
