Is It Contagious?
Psoriasis is not contagious, so it can’t be passed from one individual to another. Also, touching the psoriatic lesion on someone else won’t cause you to develop psoriasis.
It’s of crucial importance to be educated on the disease as many people still think that it is contagious.
Psoriasis – Causes
Doctors are unsure as to what exactly causes this condition. However, research showed two key factors playing an important role in developing the disease. They are the immune system and genetics.
Psoriasis is an autoimmune condition, which means that it is the result of a body attacking itself. In the case of psoriasis, white blood cells which are known as T cells attack the skin cells when they are not supposed to.
In a typical body, the purpose of the white blood cells is to attack as well as destroy any invading bacteria and fight the infections. What the mistaken attack in a person with psoriasis usually does is causing the production process of skin cells to go into overdrive. Sped-up skin cell production, however, causes all the new skin cells to develop extremely quickly; they become pushed to one’s skin’s surface where they start piling up.
Some people can inherit genes that make them much more likely to develop this condition. In case you have an immediate family member with this skin condition, then your risk for developing this disease is higher. But the percentage of individuals who have psoriasis as well as a genetic predisposition is small; approximately two to three percent, according to NPF or the National Psoriasis Foundation.
