Is that vitiligo you're worried about contagious?

In daily life, some people keep vitiligo sufferers at a distance. They are not only afraid of the visual fear caused by white spots, but also afraid that the white spots on the patient's body will infect them. The idea that vitiligo is contagious is ingrained in some people's minds. Why is this misconception?

Some infectious skin diseases, such as leprosy, have decolorization changes similar to vitiligo,which makes people think this is vitiligo. So many people think vitiligo is a kind of infectious skin disease. But in fact, the occurrence of vitiligo is due to the decolorization changes caused by local skin melanin metabolism disorder, except for hypopigmentation, there are no other abnormal changes.

The transmission of infectious diseases requires a source of infection, a certain transmission route and susceptible population, while vitiligo is not caused by external pathogen infection, there is no source of infection. So contact with vitiligo patients will not be infected, vitiligo itself is not an infectious disease. Therefore, in life, people do not need to fear vitiligo patients. We should treat them kindly and let patients with vitiligo enjoy the treatment of normal people.
