SLE is a chronic autoimmune disease with multisystem damage and is a type of rheumatic immune disease, mostly seen in female patients. Due to lack of understanding, many people think that SLE is an infectious disease. In fact, it is currently believed that the onset of SLE is related to genetics, estrogen, infection, ultraviolet light, medications and other factors, but it is by no means an infectious disease. First of all, we should know that SLE does not fit the characteristics of an infectious disease. This is because it is not a disease directly caused by pathogens such as bacteria and viruses, nor is it transmitted through the respiratory, gastrointestinal, or blood channels. It is currently believed that abnormal immune inflammation is the causative feature of SLE, but the exact pathogenesis remains unclear. Secondly, medical doctors around the world have done corresponding studies on whether female SLE patients can inherit the disease to their offspring. At present, it is believed that although SLE has a certain tendency to be inherited, it is by no means 100% hereditary, and whether it develops depends on many factors such as personal constitution and living environment. Finally, it can be confirmed that SLE is not likely to be transmitted to people around us, so we can try to relax the mode of living together in caring for patients with the disease around us to avoid increasing the psychological burden of patients and affecting the treatment process.
