yes. $4 million per year. Less than is spent on hay fever. Compare to Multiple Sclerosis, not a particularly well-funded disease, and with fewer patients, but which already has actual treatments: $144 million. Compare to Parkinson's (or Alzheimer's, I forgot which), which is similarly not well understood, $500 million (or $550 mil, I don't recall which).
Then consider that of that $4 million, those monies are actually spent on random fatigue and depression conditions which DO NOT meet the CDC's official criteria for CFS (see Dr. Lenny Jason's article which you can read in full
here, although the results are published under the title of CFS... please check out some samples of the CDC's fine handiwork
here and
here), and diverted to other programs because the CDC can't think of anything constructive to do with it.
And do look at Mindy Kitei's blog
www.cfscentral.com,
Hillary Johnson's site
www.oslersweb.com (and her book by the same title: Osler's Web: Inside the Labrynth of Chronic Fatigue Syndrome),
and Mary Schweitzer's essays:

and no, much of the (comparatively little) research going on is done by private and university funding. Nothing important we know was done by our health authorities (although some of this work done by independent and universisty groups had grants from NIH).
