No. Plaque psoriasis is not contagious; it is an immune-related chronic skin condition and will not be transmitted to others through daily contact, sharing utensils, or physical contact. Therefore, there is no need to worry excessively about the risk of transmission, but patients are advised to seek medical attention promptly and manage their symptoms through proper care.
This can be understood from the following points:
1. The cause is not related to infection.
The occurrence of plaque psoriasis is mainly related to abnormal immune system function and genetic factors, and is not caused by bacteria, viruses or fungi. Although its skin manifestations are obvious, there is no source of infection in the lesion sites.
2. It will not spread through everyday contact.
Common everyday behaviors such as shaking hands, hugging, and sharing personal items do not lead to the transmission of diseases. The skin scaling in psoriasis is simply a result of accelerated epidermal metabolism and is not contagious.
3. It is important to distinguish it from infectious skin diseases.
Some infectious skin diseases (such as tinea and scabies) may also present with erythema or desquamation, which can be easily confused with psoriasis. If any abnormalities appear on the skin, you should seek medical attention promptly for a proper diagnosis to avoid misdiagnosis.
To better address this issue, patients are advised to maintain healthy lifestyle habits and avoid mental stress and skin damage; they should also follow their doctor's instructions for long-term care, such as using gentle skincare products and having regular check-ups. Family and society should also provide understanding and support to reduce the patient's psychological burden.
