U.S. probes rash of health incidents among diplomats in Vienna

People who are believed to have been affected have reported headaches, dizziness and symptoms consistent with concussions, with some requiring months of medical treatment.

The Biden administration is investigating a recent rash of mysterious health incidents reported by American diplomats and other government employees in Vienna, Austria, U.S. officials said July 16. Some of the symptoms are similar to those first reported by U.S. diplomats and spies in Havana, Cuba, in 2016 and 2017 for which no definitive cause has yet been determined, according to the officials, who said more than 20 new cases were being looked into by medical teams at the State Department and elsewhere, including the Pentagon and CIA. “In coordination with our partners across the U.S. government, we are vigorously investigating reports of possible unexplained health incidents among the U.S. Embassy Vienna community,” the State Department said. “Any employees who reported a possible UHI received immediate and appropriate attention and care.”
