Possible Havana syndrome incident delayed Harris flight to Vietnam

Vice President Kamala Harris’ departure for Vietnam was delayed by several hours Tuesday afternoon after her office was informed by the US embassy in Hanoi, Vietnam, of a “report of a recent possible anomalous health incident.”

That term is the way that the government usually refers to the mysterious Havana syndrome that has sickened hundreds of US officials over the past few years.

“Earlier this evening, the Vice President’s traveling delegation was delayed from departing Singapore because the Vice President’s office was made aware of a report of a recent possible anomalous health incident in Hanoi, Vietnam. After careful assessment, the decision was made to continue with the Vice President’s trip,” said Rachael Chen, spokeswoman for the US embassy in Hanoi, in a statement.

Aboard Air Force Two, Harris’ chief spokeswoman Symone Sanders told traveling reporters that Harris is “well, all is fine and looking forward to meetings in Hanoi tomorrow.” Later she said of the delay: “This has nothing to do with the vice president’s health,” according to a pool report.

The intelligence community still doesn’t have an official explanation for Havana syndrome, which is a perplexing mix of sensory experiences and physical symptoms that have now sickened hundreds of US diplomats, spies and troops around the globe — some severely enough to force their retirement.

CNN has not reported any cases of Havana syndrome in Vietnam.

Harris eventually took off from Singapore’s Paya Lebar Air Base at 7:32 p.m. local time, after a more than three-hour delay.

Incidents of Havana syndrome began in late 2016 in Cuba and a Senate committee said earlier this year that the number of suspected cases appeared to be on the rise.

Victims of Havana syndrome have reported a varying set of symptoms and physical sensations, including sudden vertigo, nausea, headaches and head pressure, sometimes accompanied by a “piercing directional noise.” Some have been diagnosed with traumatic brain injuries and continue to suffer from debilitating headaches and other health issues years later.

US federal investigators have struggled to determine what or who is causing the mysterious symptoms. There have been cases reported in Russia, China and other countries across the globe. Last month, Austrian authorities said they were investigating reports that US diplomats in Vienna had experienced symptoms of Havana syndrome.

Earlier this year, CNN reported on two separate incidents that occurred near the White House late last year affecting National Security Council staffers.

Two defense officials said in May that the Pentagon was drafting a memo to the entire US military and civilian workforce asking personnel to report any so-called anomalous health symptoms that might indicate they have been victims of Havana syndrome.

CNN reported earlier this month that frustration is rising among rank-and-file staffers in the State Department and diplomats over what multiple officials say has been a tepid response by department leadership, including Secretary of State Antony Blinken.

The reported incident comes in the middle of Harris’ trip to Singapore and Vietnam, as the vice president looks to convey to the Southeast Asian nations that the US is sincere in its long-term commitment to the region.

White House officials say Harris’ overarching mission of the trip is to shore up relationships with regional partners. She is expected to focus on regional security issues amid concerns over China’s territorial claims in the South China Sea; economic priorities, including supply chain issues like global chip production; climate change; and the Covid-19 pandemic.

It’s her second trip abroad as vice president. Earlier this year, she traveled to Central America — a trip that also saw travel issues as Harris had to switch planes moments before leaving for Guatemala due to a technical glitch.
