Between late 2016 and May 2018, several U.S. and Canadian diplomats in Havana complained of health problems from an unknown cause. China and Cuba have denied any such actions. Diplomats in some postings have been plagued with nausea, headache, dizziness and other unexplained symptoms. Since 2016, the so-called Havana syndrome has afflicted more than 40 U.S. diplomats at the U.S. Embassy in the Cuban capital and at least a dozen more at the U.S. Consulate in Guangzhou, China. The State Department said in June 2018 that it had brought home diplomats from Guangzhou, China, over concern they were suffering similar symptoms.
Between late 2016 and maybe an year earlier, several U.S. and Canadian bureaucrats in Havana researched and ruled out any warships in the ocean.
