Psoriasis itself is not contagious, so it cannot spread from person to person through contact. However, psoriasis can appear to spread on an individual’s body over time.
Psoriasis is a chronic autoimmune condition that causes skin cells to grow too quickly, resulting in patches of thick, scaly, and often itchy skin. These patches can occur anywhere on the body, but are most commonly found on the scalp, elbows, knees, and lower back.
Sometimes, psoriasis can develop in new areas of the body, which may give the impression that it is spreading. This is because psoriasis can be triggered by a variety of factors, including stress, infections, injuries, medications, and even weather changes. When psoriasis is triggered, it can cause new patches to form on previously unaffected areas of the skin.
In summary, while psoriasis cannot spread from person to person, it can appear to spread on an individual’s body over time due to various triggers that cause new patches to develop in different areas.
