Officials Investigate Two Possible Cases Of Mysterious ‘Havana Syndrome’ That Delayed Harris’ Flight

U.S. authorities are investigating two potential cases of the mysterious illness Havana Syndrome that delayed Vice President Kamala Harris’ trip to Vietnam on Tuesday.

Harris’ flight from Singapore to Vietnam was temporarily halted Tuesday following reports of a “recent possible anomalous health incident” in Hanoi, according to the U.S. Embassy and Consulate in Vietnam. “Anomalous health incident” is a term used by the State Department to refer to unexplained and mysterious medical symptoms more commonly known as “Havana Syndrome,” which was first reported affecting diplomatic personnel in Cuba in 2016.

State Department officials are continuing to investigate two possible cases of the illness that affected U.S. personnel in Hanoi, according to the Associated Press. Officials began the investigation before Harris arrived in Vietnam, temporarily delaying her flight before deeming it safe for her to travel to the embassy.

Officials did not say who was affected by the illness, but did confirm they were not working for the White House or Harris, according to the AP.

“We, of course, take any reported incident of Havana Syndrome seriously,” White House Press Secretary Jen Psaki said in a briefing Tuesday. “And while this is not a confirmed case at this point in time, we take any reported incident — which was recent and was reported publicly, I will note — quite seriously.”

Symptoms of Havana Syndrome include ear-popping, vertigo, severe headaches, nausea, and a ringing in the ears. The CIA, State Department, and Department of Defense launched an investigation into the origins of the illness in April 2021.

The U.S. Embassy in Hanoi did not immediately respond to the Daily Caller News Foundation’s request for comment.
