Discoid lupus is contagious?

Discoid lupus is not contagious. Discoid lupus is not an infectious disease. It is an autoimmune disease. The patient's body fluids or respiratory secretions are not infectious. Close contact does not cause infection. Discoid lupus is directly related to immune damage in the body. Abnormal immune cells and molecules exist in the patient's body. These immune inflammatory substances can cause damage to the body tissues. The occurrence of discoid lupus erythematosus is also closely related to heredity. This disease will gather in families, but direct infection will not occur. It is recommended to go to the Rheumatology and Immunology Department for diagnosis and treatment.
