Once scoffed at, as many believed it was a precision Sonic
Nineteen Americans are suffering from a range of symptoms, including mild traumatic brain injury and hearing loss, related to mysterious "sonic harassment" attacks in Cuba.
Previously, U.S. officials said the incidents started in December 2016 and ended this past spring. But State Department spokesperson Heather Nauert revealed Friday that a new incident occurred in August and is now part of the ongoing investigation.
"We can’t rule out new cases as medical professionals continue to evaluate members of the embassy community," warned Nauert, who has described the situation as "unprecedented."
The U.S. government, including the FBI, continue to investigate who and what are behind the incidents, but with no firm answers so far.
The American Foreign Service Association said Friday that its representatives met this week in Washington, D.C., with Foreign Service Officers posted at the U.S. embassy in Havana who have faced diagnoses including mild traumatic brain injury and permanent hearing loss, but also loss of balance, severe headaches, cognitive disruption and brain swelling.
Traumatic brain injury is caused by a violent blow or jolt to the head or body that may cause temporary dysfunction of brain cells or more lasting damage, according to the Mayo Clinic. Symptoms can be immediate or appear days or weeks later, ranging from loss of consciousness or confusion to sensory problems, memory loss, or headache and nausea.
