Psoriasis

Psoriasis is not contagious; you cannot catch it from another person or spread it to someone else through skin-to-skin contact.

Understanding Psoriasis

Psoriasis is a chronic autoimmune skin condition that speeds up the life cycle of skin cells. It causes cells to build up rapidly on the surface of the skin, forming scales and red patches that are itchy and sometimes painful.

Key Fact: Psoriasis is not contagious; you cannot catch it from another person or spread it to someone else through skin-to-skin contact.
