Demodicosis / ˌ d ɛ m ə d ə ˈ k oʊ s ɪ s /, also called Demodex folliculitis in humans [1] and demodectic mange (/ d ɛ m ə ˈ d ɛ k t ɪ k /) or red mange in animals, is caused by a sensitivity to and overpopulation of Demodex spp. as the host's immune system is unable to keep the mites under control. Demodex is a genus of mite in the ...
Mange (/ ˈ m eɪ n dʒ /) is a type of skin disease caused by parasitic mites. [1] Because various species of mites also infect plants, birds and reptiles, the term "mange", or colloquially "the mange", suggesting poor condition of the skin and fur due to the infection, is sometimes reserved for pathological mite-infestation of nonhuman mammals.
Notoedric mange, also referred to as Feline scabies, is a highly contagious skin infestation caused by an ectoparasitic and skin burrowing mite Notoedres cati (Acarina, Sarcoptidae). N. cati is primarily a parasite of felids , but it can also infest rodents , lagomorphs , and occasionally also dogs and foxes.
Symptoms may continue for two to four weeks following treatment. [13] If after this time symptoms continue, retreatment may be needed. [13] Scabies is one of the three most common skin disorders in children, along with ringworm and bacterial skin infections. [15] As of 2015, it affects about 204 million people (2.8% of the world population). [9]
Mange causes severe itching and hair loss, and may cause infection if the animal scratches their skin open. Mange can be fatal if untreated, according to the U.S. Fish and Wildlife Commission .
There are two types of mange, sarcoptic mange and demodectic mange. The Demodex mite lives at low levels in most dogs, not usually causing a problem. However, in young or immunocompromised animals ...
Humans become infested by Sarcoptes scabiei var. hominis; [1] other mammals can be infested with different varieties of the mite. They include wild and domesticated dogs and cats (in which it is one cause of mange), ungulates, wild boars, bovids, wombats, [2] koalas, and great apes.

The closely related term, mange, is commonly used with domestic animals and also livestock and wild mammals, whenever hair-loss is involved. Sarcoptes and Demodex species are involved in mange, but both of these genera are also involved in human skin diseases (by convention only, not called mange).
