Psoriasis is a chronic (long-lasting) disease. It develops when a person’s immune system sends faulty signals that tell skin cells to grow too quickly. New skin cells form in days rather than weeks.

The body does not shed these excess skin cells. The skin cells pile up on the surface of the skin, causing patches of psoriasis to appear.
Psoriasis may look contagious, but it’s not.

You cannot get psoriasis from touching someone who has it. To get psoriasis, a person must inherit the genes that cause it.

Some people get more than one type. Sometimes a person gets one type of psoriasis, and then the type of psoriasis changes

Types of psoriasis:
If you have psoriasis, you will have one or more of these types:



INVERSE: (also called flexural psoriasis or intertriginous psoriasis).


When pus-filled bumps cover the body, the person also may have:

ERYTHRODERMIC: (also called exfoliative psoriasis).

If it looks like a person has erythrodermic psoriasis, get the person to a hospital right away. The person’s life may be in danger.
