If I could answer some of the questions about postviral syndromes I could become quite wealthy-very little is understood. It is diagnosed based on a patient's symptoms, there is no test to do this. Look into the history of chronic fatigue syndrome. There are as many theories concerning the cause as there is in the case of ball lightning. It appears to involve subtle changes in the immune system, possibly t1/t2 lymphocyte dominance but as I said it does remain a mystery despite extensive research. It can range from relatively mild symptoms to incapacitating ones and again why this is so remains unexplained. Some patients improve over time and others do not.
