 The relations between CUBA and USA have been filled with bizzare and comical attempts by  US  intelligence agencies to bring down the  Castro regime.
As soon as Trump took over  there has been a sustained effort to reverse all the work done by Raul Castro and Barack Obama to restore relations between the two countries.
USA which has cordial relations with communist giants Russia and China keeps punishing the poor , tiny island nation of CUBA.
the latest is the funny report in JAMA.

US EMBASSY WORKERS IN CUBA FOUND TO HAVE BRAIN
ABNORMALITIES, REPORT SAYS

Wednesday's report makes clear that the findings are preliminary, essentially a listing of symptoms and tests. And important complications remain, including that there's no information to compare the patients' brain or hearing health before they went to Cuba.

"Before reaching any definitive conclusions, additional evidence must be obtained and rigorously and objectively evaluated," JAMA associated editor Dr. Christopher Muth cautioned in an accompanying editorial. He noted that many of the symptoms overlap with a list of other neurologic illnesses.

"It really looks like concussion without the history of head trauma," report co-author Dr. Douglas Smith of Penn's Center for Brain Injury and Repair, said in a podcast provided by JAMA.

He said that sound, heard by 18 of the 21 patients, couldn't be to blame: "There is no known mechanism for audible sound to injure the brain. We have to suspect that it's a consequence of something else."

The mysterious case has sent U.S.-Cuba relations plummeting from what had been a high point when the two countries, estranged for a half-century, restored relations under President Barack Obama in 2015.

The new report outlined the battery of testing the patients underwent, including some findings that can't be even unconsciously altered, bolstering the doctors' belief that the symptoms were not mass hysteria. At least six people had a change in work performance noted by supervisors and colleagues, the JAMA report found.

Viruses or chemical exposures are unlikely, Smith's team wrote, although they couldn't be "systematically excluded."

Advanced MRI scans spotted "a few" changes in what are called white matter tracts of the brain in some patients, with three showing more than would be expected for their age, the report said. But the authors acknowledged those abnormalities could be due to something earlier in life.

For many the symptoms lasted months, and doctors designed customized rehabilitation therapy that did seem to help.

Dr. S. Andrew Josephson, neurology chairman at the University of California, San Francisco, who wasn't involved in the study, called the work "a really important step" because it carefully describes the medical findings and shows they are remarkably similar across the group of patients.

"It moves you closer to understanding what the possible causes may be," he said.

The State Department, which wasn't involved in writing the article but reviewed it to ensure it did not contain any classified information, issued a health alert Wednesday citing the article "in order to inform U.S. citizens and medical providers."

"We encourage private U.S. citizens who have traveled to Cuba and are concerned about their symptoms to share this article with their doctor," the State Department said.
