All Lupus Cases May Be Linked To a Common Virus, Study Finds

One of the most common viruses in the world could be the cause of lupus, an autoimmune disease with wide-ranging symptoms, according to a new study. From a report: Until now, lupus was somewhat mysterious: No single root cause of the disease had been found, and while there is no cure, there are medications that can treat it. The research, published in the journal Science Translational Medicine, suggests that Epstein-Barr virus -- which 95% of people acquire at some point in life -- could cause lupus by driving the body to attack its own healthy cells. It adds to mounting evidence that Epstein-Barr is associated with multiple long-term health issues, including other autoimmune conditions. As this evidence stacks up, scientists have accelerated calls for a vaccine that targets the virus. "If we now better understand how this fastidious virus is responsible for autoimmune diseases, I think it's time to figure out how to prevent it," said Dr. Anca Askanase, clinical director of the Lupus Center at Columbia University, who wasn't involved in the new research.
