Sarcoptic mange is considered contagious to which of the following?

Sarcoptic mange, caused by the Sarcoptes scabiei mite, is indeed considered contagious to both dogs and humans. This mite infests the skin, leading to intense itching and discomfort. When dogs are infested, they can spread the mites through direct contact with other animals or humans, as the mites can survive for a short period off the host.

The ability of the mange mite to affect humans, although it does not establish long-term infestations, highlights its zoonotic potential. In humans, the infestation usually results in a temporary skin irritation rather than the severe skin disease seen in dogs.

This is why the correct choice encompasses both dogs and humans, affirming the contagious nature of sarcoptic mange between these species. Other options could mistakenly suggest a more limited or incorrect range of affected hosts.
