The only manifestations of the scabies disease are itching and a rash. Scabies is a highly contagious skin disease and can produce epidemics within communities, boarding schools, households, etc. Only brief, casual contact with an individual who is infested with mites is required for transmission. Personal hygiene and cleanliness are not related to getting scabies. Individual sensitivity to the mites vary greatly among persons; one person with scabies may suffer unbearable itching, while some will find they itch little to none with scabies.
