What exactly is soriases and is it contagious?

I saw soars all over the body on someone recently and didn't let him touch me, he got offended but it looked terrible and like open wounds. He said 'it's only soriases' but I got creeped out. Please help explain this.

Answer:
Psoriasis is not contagious. It's a skin condition caused by the body's immune system attacking skin cells. One of the effective treatments is an immunosuppressive cream, which reduces inflamation at the site of application without suppressing the immune system as a whole.
