No: Psoriasis is an immune-mediated disease that affects the skin. It occurs when the immune system mistakes the skin cells as a pathogen, and sends out faulty signals that cause overproduction of new skin cells. Psoriasis is not contagious. If your diagnosis is correct there is no possibility of this.
