Psoriasis, also known as psoriasis, has become one of the world’s four most persistent skin diseases as the entire global living environment has changed and more and more people suffer from psoriasis worldwide. According to incomplete estimates, about 125 million people worldwide are afflicted by psoriasis; the causes of psoriasis are relatively complex and the etiology is still unclear. Through research most scholars believe that it is related to genetics, infection, metabolic disorders, immune dysfunction, endocrine disorders, and environment. It is a serious chronic inflammatory disease regardless of age, gender or race. Although it is not contagious and not life-threatening, it is long-lasting and known as an undead cancer. Once suffering from psoriasis, the patient is in endless pain. Psoriasis has drawn the attention of people all over the world, and the “First World Psoriasis Congress” organized by the International Psoriasis Association in the United States in 2006 established October 29 every year as World Psoriasis Day. Perhaps World Psoriasis Day is not a happy holiday for many psoriasis patients, but every patient should understand that the purpose of Psoriasis Day is to draw the world’s attention to psoriasis patients as well as to raise the correct awareness so that psoriasis patients can receive better treatment. World Psoriasis Day is an excellent opportunity to bring psoriasis and psoriatic arthritis to the attention of our national leaders; policymakers need to understand the importance and need for the Psoriasis Foundation to fund research in the field of psoriasis so that people with psoriasis can receive better treatment,” said Gail Zimmerman, president and CEO of the Psoriasis Foundation. “. On October 29th the International Federation of Psoriasis Associations, IFPA its member associations and support groups held events around the world to raise the right awareness of psoriasis and its sufferers and to give psoriasis sufferers the attention and respect they deserve.
