According to Dan Vergano of BuzzFeed,News, the U.S. State Department has mismanaged its investigation of the medical problems experienced by some U.S. diplomats stationed in Havana since December 2016.
This report says, “much of the early research into the mystery may have been botched or biased. The initial investigation was confined to two competing sets of researchers, both eager to publish studies on their own work, and whose findings have been at odds with each other. In one case, researchers were also seeking to promote their own newly approved medical device as a diagnostic tool. And until now, the effort has lacked broader oversight by an institution capable of cross-disciplinary research.”
The initial two medical teams “diagnosed the diplomats with injuries centered on their own respective areas of research expertise: inner ear damage and concussions.” Another team from the Center for Disease Control was asked to investigate over a year ago and has not yet submitted a report. Now the U.S. National Academy of Sciences will be starting yet another investigation, but there is concern this may be too late.
