American diplomats in Cuba may have been exposed to pesticides, not “sonic weapons”

American diplomats in Cuba may have been exposed to pesticides, not “sonic weapons”

The illnesses were reported after increased fumigation efforts in the wake of the Zika outbreaks.

Legal Insurrection readers may recall that in 2017, after several American diplomats developed odd neurological problems that were theorized to be caused by sonic attacks, President Donald Trump ordered all non-essential personnel out of Cuba, then sent 15 Cuban diplomats packing.

Subsequently, in May of 2018, American diplomats in China developed similar symptoms.

Now, a new study proposes that the affected employees may have been exposed to a pesticide that caused their health effects.

The mysterious high-pitched buzzing sound associated with the so-called “sonic attacks” on nearly 40 U.S. and Canadian diplomats living in Cuba may have been caused by a neurotoxic agent used to kill mosquitoes, a new study commissioned by the Canadian government claims.

…There have been various theories floated – everything from crickets to microwave weapons – as to the cause of the headaches, dizziness and other concussion-like symptoms.

Global Affairs Canada commissioned a clinical study to get to the bottom of the case.

“The working hypothesis actually came only after we had most of the results,” Alon Friedman, the study’s lead author, told Canada’s CBC News.

The suite of symptoms was described as the “Havana syndrome” and included headaches, blurred vision, dizziness, and tinnitus.

Canadian diplomats were affected by similar reactions to US counterparts – though the study noted that the symptoms of the Canadians were more gradual than the “acute, directional… auditory stimulus” in some of the US cases.

The study notes that tests carried out on 28 participants – seven of whom were tested both before and after being posted to Havana – support a diagnosis of brain injury acquired by diplomats and their families while in Cuba.

The patterns of brain injury “all raise the hypothesis of recurrent, low-dose exposure to neurotoxins”, the report said.

Specifically, the results were “highly suggestive” of something called cholinesterase inhibitor intoxication.

Cholinesterase is an important enzyme in the human nervous system, and blocking it through an inhibitor can lead to death. The chemical weapon, Sarin, is an example of a potent cholinesterase inhibitor, as is VX, which was used in the killing of Kim Jong-nam, the half-brother of North Korea’s leader.

But the low, consistent doses the researchers believe were delivered are consistent with exposure to commercial pesticides, the study’s authors said.

The timing is suggestive: The Cubans had stepped-up their fumigation efforts in the wake of the Zika outbreak.

Some pesticides work by inhibiting cholinesterase, the report said, and during the 2016-2018 period when diplomats became ill normal fumigation in Cuba was stepped up due to the Zika epidemic in the Caribbean.

The report said the diplomats’ illnesses coincided with increased fumigation in and around residences where they lived. One of the authors of the study, the professor Alon Friedman, clarified in an email to Reuters that both Canadian and Cuban authorities were fumigating.

I think this theory is possible, but were they spraying in China, too? Also, were any Cubans suffering from the same illness?

My first thought is how have the Cubans themselves been affected? How diligent in wearing protective gear were the workers who sprayed the pesticides? I should think others would have symptoms as well. Or did they only spray around the Americans?

Obamacare in cuba is working out great.

When the hell are we going to repeal that monsterous, fascistic law?

“The working hypothesis actually came only after we had most of the results…”

Stated as if that was an exception instead of the rule for science.

    There is always more investigation to do in science, this case needs the same. Too many unanswered questions, and even if it was an accident, we have a bunch of people seriously damaged. Will their lives ever be the same?

Parathion could have caused some of these symptoms. I remember as a kid, when I walked in the field after the crop duster sprayed parathion, I would get a tingling feeling in my fingers and toes. It’s a well-known cholinesterase inhibitor, both in insects and in mammals. It has a characteristic odor that the people affected should be able to identify.

cholinesterase inhibitors are not exactly a safe pesticide.

The US State Department requires fumigation too.
