The FBI has revealed for the first time that some of its agents may have had symptoms of the mysterious “Havana Syndrome.” NBC News first reported the bureau’s recognition of potential agent cases after the outlet received internal emails that showed an agent had reported possible brain injury symptoms after working in a country near Russia a decade ago. About 200 American diplomats, officials, and their family members are believed to have been hit by the mysterious illness — described by the US government as “anomalous health incidents” – while overseas.

Symptoms include migraines, nausea, memory lapses, and dizziness.

The US government has never openly held any nation responsible for the incidents. A number of alternative solutions have been put forward — including that crickets are to blame for the disease. Victims and lawmakers have lashed at federal agencies for not taking the illness seriously, and current and former officials told Reuters the FBI had previously been skeptical of agents’ reports of experiencing Havana Syndrome symptoms. “The FBI takes all US government personnel who report symptoms seriously,” the bureau said in its statement.

The agency also recalled its Vienna chief of station in September due, in part, to his claimed mishandling of reported Havana Syndrome cases. The station chief, whose identity is highly classified, expressed doubt that the reports of illness were genuine, the Washington Post reported at the time.
