This subject came up in the Bell lecture thread and I did a quick search. Sounds like the same disease to me. This correlates with what Dr. Bell said about the percentage of his patients who recovered. He did also mention that further follow-up studies show the "recovered" patients taking a downturn.

Rsum / Abstract

Background: In 1984, an outbreak of an illness characterized by prolonged unexplained fatigue was reported in West Otago, New Zealand. This outbreak resembled other reported outbreaks of epidemic neuromyasthenia in that affected individuals presented with a spectrum of complaints ranging from transient diarrhea and upper respiratory disorders to chronic fatigue syndrome (CFS). Objective: To obtain a perspective on the natural history of CFS not possible in clinic-based studies.

Methods: Twenty-three of the 28 patients in the original report were contacted and asked to complete written questionnaires. Interviews were obtained in person or via telephone. Results: Ten (48%) of the 21 patients with satisfactory interviews appeared to meet the current Centers for Disease Control and Prevention (CDC) case definition of CFS, and 11 were classified as having prolonged or idiopathic fatigue.

A return to premorbid activity was seen in most (n= 16) patients, although some reported the need to modify their lifestyle to prevent relapses.

A female predominance was noted in those meeting the CDC case definition for CFS, whereas males predominated in patients diagnosed as having prolonged or idiopathic fatigue. Conclusions: The high proportion of patients recovering from CFS in the West Otago cluster suggests that epidemic-associated CFS has a better prognosis than sporadic cases. Female sex was confirmed as an important risk factor for CFS.

This review wasn't very popular with some of the patients in NZ. Some felt that he played down the level of disability that he reported. Also patients were left off and only found out about it afterwards. There was a lot of controversy.
