hands, genitals, or your whole body. Psoriasis is an
autoimmune disease; that is, your immune system

Psoriasis is a common autoimmune disorder, affecting approximately 2 to 3% of
the world population. Its cause is unknown, but there is probably a hereditary factor; your risk of developing
psoriasis is 5 to 10% higher if you have a parent affected. In addition, race may play a role in its onset;
psoriasis is more common among white skin individuals.
Unlike many other incurable diseases, psoriasis is
not contagious or life threatening; it may, however, make your life miserable when it develops on the palms of
your hands, your soles (the
bottom of your feet), in the folds of your joints, or on your genitals. The disagreeable effects of the lesions
may impact negatively your emotional, social and personal life.
