Systemic lupus erythematosus is not contagious.
Firstly, systemic lupus erythematosus is an autoimmune disease with an unclear cause. It can affect multiple organs including the heart, lungs, and kidneys. It is classified as an autoimmune disease and not a contagious one, so there is no need to worry about it spreading. However, this condition does have a certain genetic predisposition. For instance, if parents have systemic lupus erythematosus, then their offspring have a relatively higher chance of developing the condition compared to families without a history of the disease. Being an autoimmune disease, it cannot be cured but can only be managed with medications such as corticosteroids to control the progression of the disease. Therefore, during the course of steroid treatment, it is vital to prevent infections. Finally, it is important to emphasize once again that systemic lupus erythematosus is not contagious and does not pose a risk of transmission, so everyone can be reassured.
