“Havana Syndrome”: how to explain this mysterious disease affecting American diplomats?

Staff at the US Embassy in Colombia are said to be suffering from “Havana Syndrome”. New cases for a phenomenon still unexplained and appeared in 2016 in Cuba.
Originally, in 2016, it was an unexplained illness that struck around twenty American Embassy employees stationed in Cuba. Patients then complain of a sort of “acoustic attack”.

Those affected also report problems with balance and dizziness, coordination, eye movement, as well as anxiety, irritability and what victims have called “cognitive fog”.

Latest cases recorded, at least two staff from the American Embassy in Bogota , Colombia, are said to be suffering from similar symptoms, reports the Wall Street Journal on Tuesday, October 12. What are the causes of such a phenomenon? Washington has so far not been able to shed all the light, but favors a few avenues.
Radio waves?
More or less far-fetched hypotheses have followed one another, such as the one suggesting that the noise in question corresponded to the mating song of a cricket, or even possible poisoning from pesticides. But according to a report from the American Academy of Sciences, “directed radio wave energy” is the most likely cause of these symptoms. Microwave beams are an explanation that comes up regularly.
