Vitiligo is a primary skin pigmentation loss with certain limitations and seems to be related to certain genetic factors. The cause and mechanism of the disease is still unclear. The actual fact is that it is a good idea to have a good look at the actual site that is damaged by sun exposure and friction.
Therefore, vitiligo is not contagious. So, why do some people think it is an infectious disease, sometimes even confused with leprosy? This is because some infectious diseases such as leprosy, can also occur in the skin some similar to vitiligo-like depigmentation damage, so it gives people an illusion that this is vitiligo. In fact, the depigmented spots that appear in patients with these infectious diseases are different from the depigmented spots that appear in patients with vitiligo. In addition to depigmentation, leprosy patients are also characterized by the loss or disappearance of superficial sensation, abnormal sweating and loss of fine hair, and sometimes neuralgia and limb deformity, while vitiligo patients do not have these symptoms. In short, vitiligo and leprosy is completely two things, people needless to vitiligo patients with fear psychology, in life they should enjoy the same treatment with healthy people.
Some vitiligo patients are afraid to donate blood for fear of being discriminated against and rejected because they suffer from leukoplakia. People also commonly have the misconception that vitiligo is a contagious disease. In fact, there is no need to have this worry, you can be sure that vitiligo is not a blood disease, so there is no more worry along with blood contagion. The reason why there is anxiety is because some people confuse vitiligo with blood disease and think that the blood of vitiligo patients also have viruses that cause the development of vitiligo and affect the health of others.
In fact, vitiligo is due to a decrease in the number of melanocytes in the skin and hair follicles or a decrease or loss of intracellular tyrosinase activity, resulting in a decrease in melanin synthesis, which triggers limited or generalized depigmentation lesions. Although endocrine and immunological alterations are found in vitiligo patients by sampling and testing their blood, it is not possible to confuse vitiligo with blood disorders as a result. The vitiligo patient is just a skin problem, and blood disease is simply a wind and horse.
