Cuba again categorically rejected the use of the term “attack,” without any evidence to support it, during a recent meeting between U.S. and Cuban scientific experts, to discuss the reported health problems of U.S. diplomats accredited to Havana.
As is known, throughout the months in which the investigation into the incidents has been conducted, Cuban scientists and specialists have not been allowed access to the doctors who evaluated the diplomatic personnel reporting different symptoms, or to their clinical information.
As a result of this recent exchange, the scientific grounds that disprove the occurrence of alleged incidents against U.S. diplomats in Havana were reiterated.
The information provided does not support the hypothesis of attacks that resulted in the range of symptoms and brain injuries to diplomats reported by the State Department.
The information exchanged does not demonstrate the existence of a new neurological disorder.
It cannot be claimed that brain injuries usually caused by blows to the head could have occurred without any cranial trauma.
The medical evidence presented has serious shortcomings.
Most of the cases described present the symptoms of common conditions such as hypertension, stress, and many others of high prevalence in the United States and around the world.
The reports may also be inaccurate, due to the average time interval of 203 days between the alleged incidents and the reported medical investigations.
Neuropsychological tests, considered more objective, were evaluated with unusual criteria that, applied to a group of healthy subjects, would deem almost all as sick.
Only three individuals were found to have mild or moderate hearing loss, each with audiograms corresponding to different and probably pre-existing diseases.
Neuroimaging did not indicate brain damage. In two individuals, mild signs of injury were reported and, in another, moderate. These were not specific and could appear as symptoms of multiple diseases, or as the result of processes that occurred before these people traveled to Cuba. Cuban experts have not been able to access these images.
