When CIA Director Bill Burns traveled to India earlier this month a member of his team reported symptoms consistent with Havana syndrome and had to receive medical attention, according to three sources familiar with the matter.

The incident set off alarm bells within the US government and left Burns "fuming" with anger, one source explained. Some officials at the CIA viewed the chilling episode as a direct message to Burns that no one is safe, including those working directly for the nation's top spy, two sources said.

The event marks the second time in less than a month that reported cases of the mysterious illness have impacted the international travel of top Biden administration officials. Last month Vice President Kamala Harris's visit to Vietnam was slightly delayed when multiple US personnel reported symptoms consistent with the syndrome just ahead of her visit, and at least two of them had to be medevaced.
