Psoriasis is an autoimmune disease that has infection on the skin. When the immune system sends faulty signals which speed up the growth cycle of skin cells, it’s when psoriasis occurs. Currently, the exact trigger of the disease is not yet discovered. At least 10% of general population may have a predisposition to psoriasis since they contain genes inherited from their ancient families. This does not actually means that a person containing these genes is infected. Psoriasis shows up when some of the triggers are involved. It’s considered that only 2-3% of the infected population develops this disease but if only he or she contains the genes that cause it and exposed to triggers of psoriasis. However, the external factors are not universal that means they may not affect other people. You can’t be infected by psoriasis if you only touch an infected person.
