Is psoriasis contagious to others?
Disease description:
I have developed some psoriasis on my arm, and I don't know much about psoriasis. May I ask whether psoriasis is contagious to others?

Psoriasis is a common chronic skin condition that is not directly contagious to others. This is because psoriasis is not caused by microorganisms such as bacteria or viruses, but rather results from an abnormal immune response leading to excessive skin cell proliferation and inflammation. Therefore, contact with individuals who have psoriasis, sharing personal items, or living together does not lead to transmission of the disease. Triggers for psoriasis include genetic, environmental, and infectious factors, which may affect individuals differently. Although psoriasis is not contagious, patients should still maintain good personal hygiene and avoid excessive scratching of affected areas to prevent worsening symptoms or secondary infections. Additionally, maintaining a positive mindset and healthy lifestyle can actively support treatment and recovery from psoriasis.
