Systemic lupus erythematosus is a chronic autoimmune disease that can damage multiple systems and affect multiple organs. Its occurrence is related to genetics, environmental pollution, hormonal levels, and infections. It is classified as an autoimmune disease and is not infectious or contagious. Once diagnosed with systemic lupus erythematosus, it is important to thoroughly complete related examinations and assess the activity level of the disease, as treatment plans vary accordingly. Therefore, for patients with systemic lupus erythematosus, there is no need to worry about it being contagious. However, there is a hereditary tendency, meaning if the parents have it, the likelihood of their children developing the disease is significantly higher than others.
