For years, doctors have been trying to find a cause for Chronic Fatigue Syndrome (CFS). The devastating illness tends to strike healthy and fairly active individuals with no other history of medical problems or conditions. Recently, doctors in California have found that over 70% of those individuals diagnosed with CFS are infected with a rare enterovirus that is almost never found in the healthy population. As a result, they believe that this enterovirus is the primary cause of many cases of CFS.
