Scabies can be spread from an infected human to another human, but animals cannot spread scabies to humans, according to the Centers for Disease Control and Prevention. Scabies, sometimes called Norwegian scabies, is highly contagious between humans, especially when the scabies lesions are crusted.
The infection is very easily spread by skin-to-skin human contact, according to the American Academy of Dermatology. Additionally, scabies can also be spread by contact with an infected person's clothing, bedding or towels, as indicated by the CDC.
Pets cannot spread human scabies. Pets are infected by a different mite that does not survive on humans. This type of scabies causes mange in animals, as reported by the CDC. There are several varieties of animal mange. Canine scabies, or sarcoptic mange, affects dogs, while notoedric mange affects cats, as reported by the Merck Veterinary Manual.
