Psoriasis is a common skin condition that causes a dry, red and scaly rash on the skin. It can develop at any age. Psoriasis is not contagious. This means you cannot catch it or spread it to other people.
We do not know what causes psoriasis. But we do know it is no one’s fault. We also know that a person’s genetics (family history) and immune system (system that fights off germs) play a role. Certain things can also bring out psoriasis or make it worse, like strep throat, colds, ear infections or skin injuries.
Dry, red, scaly and itchy patches on the skin. These patches can sometimes burn. The patches come and go. They can also stay for long periods of time.
Psoriasis is common. It affects 1-2 out of every 100 people.
