Does obvious vitiligo on the arm spread to others?
Disease description:
My classmate has vitiligo on his arm. It looks quite alarming, but no one else in his family has it. Is the obvious vitiligo on his arm contagious?
The obvious白癜风 (vitiligo) on the arms is not contagious. Vitiligo is a skin and mucous membrane depigmentation disorder. Its occurrence is related to multiple factors such as family genetics, autoimmune diseases, and neurochemical substances, but it is not infectious. The main symptom of vitiligo is the appearance of white patches on the skin, which result from the decline or loss of melanocyte function and are not caused by pathogens. Therefore, contact with vitiligo patients does not lead to disease transmission. Patients need not worry about passing vitiligo to others but should actively cooperate with doctors for treatment to control the progression of the condition.
