What is Psoriasis
About PsoriasisPsoriasis (suh-rye-uh-sis) is a chronic inflammatory disease that manifests in the skin, joints, and other organs as associated conditions. It is more than a “skin” disease. It is thought to be a chronic inflammatory disease with an autoimmune component . There are five major forms of psoriasis: plaque, guttate, pustular (generalized and localized), inverse, and erythrodermic. Most people living with psoriasis will suffer from one type, but some may be affected by more than one at a time, or during different stages throughout their life. Knowing about psoriasis and being better informed about the effects of psoriasis on those living with it will lead to better disease management and treatment outcomes. Psoriasis is NOT contagious. It is not an infectious disease.
