Systemic lupus erythematosus is also called SLE or simply, lupus. It is a disease characterized by general symptoms of feeling bad, arthritis, and skin lesions, with gradual or rapid progression to serious manifestations, such as pneumonia, disabling arthritis, and kidney failure. Lupus is a member of the group of diseases called "collagen diseases," which include also rheumatoid arthritis, dermatomyositis, and others. Lupus often starts with a fever of unknown cause which lasts for days, weeks or months. A rash, typically in the "butterfly area" of the face, may begin at that time. The disease is caused by an alteration in the chemical structure of collagen, a type of connective tissue fiber especially common in blood vessels, lungs, kidneys, skin, and the lining membranes of joints and body cavities. The organs where the connective tissue collagen fibers are most numerous will be most severely afflicted by the disease symptoms.
There have been studies done to see if there are geographic causations for lupus, but all of these studies have either been inconclusive or discarded because of inaccurate methods. So far, Lupus has been found to occur in all types of geographic locations, from very cold climates to very hot climates...from sunny climates to rainforest-type climates. The occurance has more to do with the chemical structure in certain ethnic races than geographic location of the patients.
I hope that I have been helpful to you.
