Mange /ˈmeɪndʒ/ 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. Thus, mange includes mite-associated skin disease in domestic mammals (cats and dogs), in livestock (such as sheep scab), and in wild mammals (for example, coyotes, cougars, and bears).^[2][3] Since mites belong to the arachnid subclass Acari (also called Acarina), another term for mite infestation is acariasis.

Parasitic mites that cause mange in mammals embed themselves in either skin or hair follicles in the animal, depending upon their genus. Sarcoptes spp. burrow into skin, while Demodex spp. live in follicles.

In humans, these two types of mite infections, which would otherwise be known as "mange" in furry mammals, are instead known respectively as scabies and demodicosis.

Sarcoptes is a genus of mites.

In some contexts, the types are all considered subordinate to Sarcoptes scabiei.

• Sarcoptes scabiei var. bovis
• S. s. var. canis
• S. s. var. caprae
• S. s. var. equi
• S. s. var. hominis
• S. s. var. ovis
• S. s. var. suis

In other cases, (as with S. equi and S. anthracis), these are sometimes considered distinct species.

The term Sarcoptes canis appears in older references,^[1] but is now usually described as Sarcoptes scabiei var. canis^[2] or Sarcoptes scabiei canis.

Scabies (also known as the seven-year itch^[1]) is a contagious skin infestation by the miteSarcoptes scabiei.^[1][3] The most common symptoms are severe itchiness and a pimple-like rash.^[2] Occasionally, tiny burrows may appear on the skin.^[2] In a first-ever infection, the infected person will usually develop symptoms within two to six weeks.^[2] During a second infection, symptoms may begin within 24 hours.^[2] These symptoms can be present across most of the body or just certain areas such as the wrists, between fingers, or along the waistline.^[2] The head may be affected, but this is typically only in young children.^[2] The itch is often worse at night.^[2]Scratching may cause skin breakdown and an additional bacterial infection in the skin.^[2]
