Answer :
Final answer:
The itching or pruritus associated with scabies is primarily caused by mites burrowing into the outer layer of skin, or the epidermis, and their feces. The body's immune response to the mites and their feces causes inflammation and itchiness.
Explanation:
The pruritus or itching associated with scabies is primarily caused by mites burrowing into the epidermis and their feces. Scabies is a skin condition caused by the infestation of a mite called Sarcoptes scabiei. These microscopic mites burrow into the epidermis, the outer layer of skin, and lay their eggs.
The mites and their feces cause an immune response in the body, which leads to inflammation and the characteristic itching sensation. It's important to note that while certain allergic reactions, toxins and topical injuries can also cause itching or rashes, these do not specifically apply to scabies. The primary cause of pruritis with scabies is the mite infestation and the body's immune response to it.
