The fact that enteroviruses have been largely ignored by the scientific community, and are generally thought of as "unsexy" as a research subject, is a major tragedy not only for CFS patients, but also for the wider community of sick people with various other illnesses. If you look at the number of both acute and chronic diseases that enteroviruses are linked to, you begin to realize that enteroviruses may well turn out the one of more nasty viruses in common circulation.
Enterovirus diseases associations are:
Brain:
Attention Deficit Hyperactivity Disorder (ADHD)
Chronic Fatigue Syndrome
Aseptic Meningitis
Encephalitis
Rhombencephalitis (inflammation of the brain stem)
Autoimmune:
Guillain-Barre Syndrome
Diabetes Mellitus Type 1
Diabetes mellitus type 2
Seronegative arthritis
Chronic Fatigue Syndrome (CFS seems to have autoimmune features)
Heart:
Myocardial infarction (Heart Attack)
Cardiac Arrhythmia
Coronary Heart Disease
Dilated Cardiomyopathy
Myocarditis
Myopericarditis
Skin:
Juvenile Dermatomyositis
Viral Exanthems
Other:
Birth Defects and Problems During Pregnancy
Nonspecific Febrile Illness
Acute Hemorrhagic Conjunctivitis
Hand, Foot, and Mouth Disease
Pleurodynia (Bornholm disease, Devil Grippe)
Polio
Herpangina
Hepatitis

Even just considering diabetes type 1 and type 1, the yearly economic cost in the US for these diseases is $14.9 billion and $159.5 billion respectively (ref:
here). My own concerns are not just for people with CFS, but also for the huge amount of ill health that is perpetrated by various infectious pathogens commonly found in circulation.
I have nothing against seeking out new viral associations with CFS, such as XMRV; but if only a fraction of the interest and replications studies that XMRV received were directed to enterovirus, I would wager that CFS would be on the way to a cure by now. So in my view, this disinterest in enterovirus research is HUGE tragedy for CFS patients, and also for the wider community of ill people with diabetes, ADHD, GBS, heart disease, etc.
