Generally, lupus erythematosus is not contagious and cannot be transmitted to others. The detailed explanation is as follows:

Lupus erythematosus is an autoimmune disease, not caused by infections from microorganisms such as viruses or bacteria. Autoimmune diseases occur when the body's immune system mistakenly attacks its own healthy tissues, leading to tissue damage and functional impairment. These conditions are non-contagious and cannot be spread through contact, air, blood, or any other route. Therefore, lupus erythematosus does not pose a risk of transmission. Patients are advised to follow medical guidance and use medications such as prednisone acetate tablets, cyclosporine soft capsules, and methotrexate tablets for treatment.

During treatment and recovery, patients should actively receive standardized therapy and take proper sun protection measures to minimize external stimuli. Additionally, since patients' skin is particularly sensitive to ultraviolet light, they should avoid consuming photosensitizing foods such as celery, parsley, and mushrooms, and reduce intake of irritating foods, which may help promote skin recovery.
