Newly disclosed Canadian government documents reveal more details about medical problems experienced by their diplomats and members of their families in Cuba.
In May 2017 one of those diplomats in a message to the government in Ottawa reported that some diplomats and members of their families, including children, had symptoms including headaches, dizziness, nausea, hearing loss, nosebleeds and cognitive issues including loss of short-term memory. “Many of the symptoms are similar to signs of extreme stress, and there is the possibility that there could be mental health effects caused by the fear of being targeted. Either way, testing should help to rule out cases and reassure personnel that we have the means to be able to provide duty of care. There are no answers. We are left to (sift through) what we know about … the targets and possible suspects.”
By June 9, the Canadian mission was underscoring the need for help from a Canadian federal medical adviser and stressing that new diplomatic personnel bound for Cuba should be made aware as soon as possible of the strange ailments affecting staff. In the meantime, local guards were asked to increase their patrols around the residential properties of Canadian staff and to be extra vigilant in reporting. This report also mentioned additional symptoms: loss of consciousness, blurred eyesight, lack of balance and ear pain. “Many have heard strange noises in their residences and have experienced symptoms that they have not had before in their lives.”
On June 18 Dr. Jeffrey Chernin of Health Canada went to Cuba to meet concerned staff individually and take part in a townhall-style meeting a few days later. The doctor found that symptoms, experience and recovery varied, but he seemed to rule out viral causes such as the flu or hearing loss due to age. He also found that the symptoms were similar to those experienced by U.S. personnel in Cuba.
Subsequently Privy Council Office and Global Affairs Canada officials held a meeting with Cuban counterparts to encourage “closer collaboration” on fact-finding, explore the possibility of greater security in areas where Canadian diplomats were living “to discourage further attacks” and express Canada’s ongoing commitment to good relations.
By August, however, it appeared the situation was not yet resolved. A Health Canada medical adviser suggested in an August 11 email that “routine audiometry,” which measures individuals’ hearing sensitivity, could be conducted as a baseline for Canada-based staff headed on posting to Havana.
