Psoriasis is an incurable skin condition that currently afflicts roughly seven million people in the United States and approximately 80 million people worldwide. Because of its scaly appearance, psoriasis is often mistaken for a rash, but if left untreated it can become deadly. Psoriasis is not a communicable disease, which means you cannot catch it from other people nor will you spread it from one body part to another simply through touch.

It is now known that the symptoms of psoriasis that affect the skin are merely an outward manifestation of an internal immune system disorder centering around the overproduction of a class of white blood cells termed T-cells. The T-cells in people with psoriasis travel to the skin's surface about 10 times faster than in normal skin. The result of which are the appearance of the classic psoriatic lesions on the skin.

Healthy skin is shed and replaced on a continuous basis through normal and regular activity. However, when a person has the most common form of psoriasis, his skin does not shed properly. Instead he must endure an incessant build up of old rough patches, called plaques, on his skin. Additionally, most experts believe that psoriasis is a genetic condition inherited from a parent.

Psoriasis Is Not Life Threatening

Although there is no known cure, most cases of psoriasis are not life threatening. In fact, in most people the symptoms come and go. Sometimes, years will elapse between outbreaks. People who develop the disease early in life are more apt to experience reoccurring outbreaks as opposed to those who develop in later in life.
