Introduction

Psoriasis is commonly referred to as “psoriasis vulgaris.” Generally, psoriasis is not contagious. If you experience any discomfort or symptoms, it is advisable to seek medical attention promptly. Patients can confidently carry out daily skin care without undue psychological stress. Keep the skin moisturized and clean in daily life, and consistently apply moisturizers to support and protect the skin barrier. Maintain a regular sleep schedule and follow a light, balanced diet to help stabilize your immune system.

Psoriasis is commonly referred to as “ox-hide psoriasis” in traditional Chinese terminology. Generally, psoriasis is not contagious. If any discomfort or symptoms arise, prompt medical consultation is recommended. A detailed explanation follows:

Psoriasis is a chronic inflammatory skin disorder. Its pathogenesis primarily involves immune dysregulation, genetic predisposition, and environmental triggers—rather than infectious agents such as bacteria, viruses, or fungi. For a disease to be transmissible, pathogenic microorganisms must spread from person to person; however, the skin lesions of psoriasis result solely from abnormal immune-mediated keratinocyte proliferation and inflammation, lacking any basis for transmission. Therefore, routine contact—including cohabitation, physical touch, or even respiratory droplet exposure—does not transmit psoriasis. There is no need to isolate or avoid individuals with psoriasis.

Patients can confidently carry out daily self-care and reduce psychological stress. Maintaining skin hydration and cleanliness is essential; regular application of moisturizers helps preserve the skin barrier. Adopting consistent sleep patterns, following a mild and balanced diet, and stabilizing immune function are also beneficial. Avoiding skin trauma, excessive sun exposure, and repeated friction—and maintaining emotional stability—are key strategies. Regular skin care further helps minimize disease flares and sustain stable skin health.
