HANOI—U.S. officials are continuing to investigate two possible cases of so-called Havana Syndrome health incidents that delayed Vice President Kamala Harris’ trip from Singapore to Vietnam.
The investigation was in its early stages and officials deemed it safe for Harris to make her scheduled stop in Vietnam, after initially hitting pause for a few hours on Tuesday. Havana Syndrome is the name for a rash of mysterious health incidents first reported by American diplomats and other government employees in the Cuban capital beginning in 2016. Harris on her trip is reassuring Asian allies after the tumultuous evacuation of U.S. forces from Afghanistan.
