There is a misconception that the disease can spread by contact. However, Vitiligo is non-contagious and does not spread by contact. Another myth is about dietary habits. For instance, people used to implicate sour food, fish, white food, etc and consider them to be the reason for vitiligo.
Potential triggers include sunburn, exposure to certain chemicals, and trauma or injury to the skin, according to the article in F1000 Research. These triggers can also prompt vitiligo to spread in people who already have the condition.
What is known is that the risk of developing vitiligo increases in kids with a family or personal history of thyroid disease, diabetes, and certain conditions like alopecia (an autoimmune disease that causes hair loss). Vitiligo is never contagious — kids can't "catch" it from someone else.
Inheritance. Vitiligo sometimes runs in families, but the inheritance pattern is complex because multiple causative factors are involved. About one-fifth of people with this condition have at least one close relative who is also affected.
The condition usually begins with small white patches in a localized area. If the vitiligo progresses it can gradually spread across the body over time.
Vitiligo signs include: Patchy loss of skin color, which usually first appears on the hands, face, and areas around body openings and the genitals. Premature whitening or graying of the hair on your scalp, eyelashes, eyebrows or beard.
The signs of vitiligo can appear at any stage of life, and include: Loss of skin color in patches, usually seen first on your face, hands, arms, legs, and feet. Premature whitening of your body hair, including facial hair, eyelashes, and eyebrows. Loss of color of the tissues inside your nose.
Anyone can get vitiligo, and it can develop at any age. However, for many people with vitiligo, the white patches begin to appear before age 20, and can start in early childhood.
If vitiligo is not treated, it may spread extensively to involve various skin areas. Rarely, some patches may go away or decrease in size. Although vitiligo is neither dangerous nor causes symptoms, such as pain or itch, the sufferers may be upset and stressed because of the way their skin appears.
Certain components of hair dye, bleaching agents, and skin-care products can set off a vitiligo flare. Marmon advises choosing products labeled hypoallergenic that are free of harsh chemicals, fragrances, and irritants.
Pityriasis versicolor can sometimes be confused with vitiligo, as they both cause the skin to become discoloured in patches. But there are ways to tell the difference: vitiligo often develops symmetrically (on both sides of your body at the same time), while pityriasis versicolor may not.
According to the American Academy of Dermatology Association, up to half of people who develop vitiligo do so before the age of 20. But despite its high incidence in childhood and early adulthood, vitiligo can happen at any age, says the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS).
Studies suggest that vitamin D3 increases tyrosinase activity and melanogenesis in vitro [12], which may lead to repigmentation in vitiligo skin lesions. Calcipotriol and tacalcitol, which are vitamin D analogs, are also known to induce repigmentation in patients with vitiligo [13,14].
How Is Vitiligo Treated? There is no "cure" for vitiligo. Sometimes patches go away on their own.
It is thought that sunlight can be both good and bad for people with vitiligo, for several different reasons. For example, on the disadvantage side, some medical experts believe it's possible that sunburn could be a trigger for developing the skin condition.
Vitiligo affects approximately 0.5% to 1% of the population. Its prevalence is similar in both genders and in all races. It can appear at any age, but it often starts before the age of 20. The disease does not affect life expectancy.
Among the biggest concerns with vitiligo is that the depigmented patches of skin are more susceptible to damage from the ultraviolet (UV) rays in sunlight. 3 This makes them prone to sunburn, and, especially if you have fairer skin, tanning makes discolored areas more prominent.
Vitiligo is not contagious
It cannot be transmitted via touch, saliva, blood, inhalation, sexual intercourse or by sharing of personal items like water bottle, bath towels, swimming pool, etc. Some people also believe that they can get Vitiligo by patting dogs with white spots on their head!
Vitiligo can also affect the hair, causing white or prematurely gray hair. Some people lose some of their eye color and see light spots on the colored part of an eye. Vitiligo can also develop inside your ear and may affect your hearing.
Signs and symptoms of vitiligo include: Patches of skin or mucous membranes that lose color. These can appear white or lighter than your natural skin tone. Patches of hair on your body turn silver, gray or white.
I look for the white spots to enhance, or become more apparent, under the Wood's lamp compared to room light, they kind of fluoresce. If this happens, the skin in the area is depigmented, meaning there is no pigment or melanin. This is always the case in vitiligo, and thus is an absolute requirement to diagnose it.
Segmental vitiligo is unique, even beyond the fact that it doesn't cross the midline. It spreads very quickly, faster than the other forms, but only for about 6 months (sometimes up to a year).
