  • Psoriasis is not a contagious disease that you can “catch” from an affected individual
  • Although some patients may experience psoriasis because of a strep infection, this still does not make the disease contagious

A big misconception surrounding psoriasis is that it can be transferred from one person to another. However,  psoriasis is most definitely not contagious.1

It’s Inflammation, Not an Infection

Psoriasis is not contagious; rather, it is an autoimmune condition,2 wherein your immune system mistakenly prompts T cells to function as if they were fighting an infection. As a result, your body’s skin cells reproduce at a rapid rate and turnover quickly.3,4 This then leads to symptoms and illnesses that may be debilitating for your body.5 Other examples of autoimmune diseases include Type 1 diabetes, multiple sclerosis, Graves’ disease and vasculitis.6

Inflammation is a major symptom of autoimmune diseases,7 psoriasis included. According to Dr. Lisa Pawelski, a dermatologist who specializes in psoriasis in Pittsburgh, Pennsylvania, this inflammation may be one of the reasons why some people believe psoriasis is contagious. As she explains in an article in Everyday Health:8

“Psoriasis is an inflammation. Both inflammation and infection can appear raised, red and angry, so it's not surprising that people sometimes fear they can catch psoriasis just by touching it. But infections are caused by bacteria, fungus, viruses and other organisms that can be passed from person to person. Psoriasis is not.”

Although some patients may experience psoriasis because of a strep infection, this still does not make the disease contagious. Pawelski further notes that this skin condition mainly arises because of an immune system problem and not an infection.9
