Regarding the problem of vitiligo infection, medical experts made it clear that infectious diseases mean that pathogens can be transmitted to others through various channels, and the primary condition of infection is pathogens. Vitiligo is a decolorizing change caused by the imbalance of melanin metabolism in some skin. There is no pathogen and no source of infection, so vitiligo is not contagious. You can feel free to make friends with white people.
We should treat friends with vitiligo correctly, not discriminate, but treat them fairly.
As for where to go for treatment, I suggest you check whether there is a local skin hospital. Only professional departments can see this disease, and instruments and equipment must be used to detect and analyze what causes vitiligo before symptomatic treatment can be carried out.
