Mange is a skin disease caused by infestation with microscopic parasitic mites that burrow into or live on the skin of animals, most commonly affecting dogs, livestock, and wildlife. The condition leads to intense itching, hair loss, redness, thickened skin, and the formation of crusts or sores. There are different types of mange, including sarcoptic mange, which is highly contagious and can temporarily affect humans, and demodectic mange, which is typically related to immune system weakness in the affected animal. Severe infestations can result in secondary bacterial infections and significant discomfort. Mange spreads primarily through close contact with infected animals or contaminated environments, making early identification important to limit transmission.
