of Zika in Sept 2016 when neighbors had thousands. For months they did not update. It turned out in later reports that a Zika outbreak did arrive and by May they announced the total was up to nearly 1900 cases.
It's also probable that Castros death sent US intelligence officers to Cuba in November. It's also a near certainty that Cuba tried to spy on them and the US has evidence of Cuban agents being nearby during the 'attacks' (since they are always nearby, right?). But since it cannot be said for sure, here we are.
And I think I have a possible theory of how all this relates to that insect noise, and ultrasound - all are normal events that fit together quite easily and do not involve any covert sonic attack. I'm currently missing some info on my proposed bug's capabilities.
eta: You are right that a missing piece is why just US workers and some Canadians? If it is environmental, then it should affect everyone, right? There would need to be some way to verify that the best-supported cases are isolated from the population surrounding them and then look for common denominators among that isolated group. I don't think it's possible to do this beyond speculation. There just isn't enough information.
*I do find it interesting that a small group of reporters seem to break all the new info from 'sources' and no one from Obama's Cuba team or Trumps is complaining of leaks or laying blame, or even being skeptical of the verity of attack claims in general.
