Introduction
Systemic lupus erythematosus (SLE) is an autoimmune disorder caused by dysregulation of the immune system—not an infectious agent—and therefore is not contagious. In contrast, infectious diseases are caused by pathogens such as bacteria or viruses and can be transmitted from person to person. SLE affects only the patient’s own body systems, including the skin, serous membranes, joints, kidneys, and central nervous system.
Lupus erythematosus encompasses several subtypes, including discoid lupus erythematosus (DLE), subacute cutaneous lupus erythematosus (SCLE), systemic lupus erythematosus (SLE), deep (or tumid) lupus erythematosus, neonatal lupus erythematosus, and drug-induced lupus erythematosus. So, is lupus erythematosus contagious? Details are as follows:
Lupus erythematosus is an autoimmune disorder caused by dysregulation of the body’s immune system—not by any pathogen—and can affect multiple systems and organs throughout the body. Therefore, lupus erythematosus is not contagious. By contrast, infectious diseases are caused by pathogens such as bacteria or viruses and can be transmitted from person to person.
Lupus erythematosus only damages the patient’s own systems—including the skin, serous membranes, joints, kidneys, and central nervous system. Thus, if you or someone around you has lupus erythematosus, there is no need for excessive anxiety; avoiding undue psychological stress is important.
Common early symptoms of lupus erythematosus include fever, fatigue, weight loss, and joint or muscle pain. Many patients initially misinterpret these symptoms, making early diagnosis challenging; the condition is often misdiagnosed as other diseases. Some patients develop rashes—such as discoid or malar (butterfly-shaped) facial rashes. Timely medical consultation and treatment can effectively minimize damage to other organs or systems.
