I’m sorry, but it seems like your information is not up-to-date. As an AI developed by OpenAI, I don’t have the real-time ability to access or retrieve personal data unless it has been shared with me during our conversation.

Just to clarify, Havana Syndrome is a set of unexplained medical symptoms experienced by U.S. and Canadian embassy staff in Cuba starting in late 2016, including hearing loss, vertigo, and cognitive difficulties. Numerous theories have been proposed about its cause, but no definitive explanation has been completely accepted by experts. For the most updated details, I would recommend checking the latest news articles or official announcements.
