Havana Syndrome is back in the news:
CIA director “fuming” after Havana syndrome strikes team member in India
Some officials fear the incidents are increasing and escalating, leaving officers on edge.
The incidents first came to light in late 2016 among US and Canadian diplomats and their families
stationed in Havana, Cuba, giving the cases their current moniker of Havana syndrome.
Comprehensive medical evaluations of some of the US personnel affected in Havana concluded they had sustained "
injury to widespread brain networks without an associated history of head trauma.”
But who and/or what is causing the incidents and injuries are still weighty unknowns. Medical and scientific experts have speculated that the cause may be anything from pesticide exposures to malfunctioning surveillance equipment, a collective delusion (mass psychogenic illness), or even simply the irritating sounds of randy crickets.
A leading hypothesis, however, continues to be that the incidents are indeed attacks, which are carried out by Russian operatives using a covert microwave-energy device. A panel of experts with the National Academy of Sciences concluded last year that directed
pulsed radio frequency energy was the "most plausible" cause of the incidents and injuries. Russian scientists have a long history of researching related technology and its effects on people. Russian authorities have reportedly
denied any involvement in the incidents.
