HAVANA, Cuba – The U.S. government confirmed Friday what Local 10 News sources in Havana disclosed in August: There were 19 Americans suffering health issues after their time in Cuba.

The U.S. State Department was investigating how sonic technology in Cuba prompted U.S. personnel and their relatives to suffer hearing loss and other ailments.
"We can't rule out new cases as medical professionals continue to evaluate members of the embassy community," State Department spokesperson Heather Nauert said Friday.
According to the American Foreign Service Association the injuries under investigation include mild traumatic brain injury and permanent hearing loss.
The Cuban government denies involvement and claimed to be cooperating with the investigations of U.S. and Canadian authorities.
"What has happened there is of great concern to the U.S. government," Nauert said. "Let me just assure you that this is a matter that we take very seriously."
