New cases of 'Havana Syndrome' grow as cause remains a mystery

NPR's Sarah McCammon talks with Stanford professor David Relman about the mysterious Havana Syndrome that continues to affect diplomats and federal employees around the world.

October 15, 2021


It was the middle of a Moscow winter about four years ago when Marc Polymeropoulos was asleep in his hotel room until suddenly...

MARC POLYMEROPOULOS: I was awoken, you know, in the middle of the night. But I had just had incredible vertigo, dizziness. I wanted to throw up.

MCCAMMON: That's Polymeropoulos speaking with NPR last October. He was on CIA business in Russia, where he had just become the No. 2 official for clandestine operations in Europe.

POLYMEROPOULOS: I started this kind of incredible journey of seeing, you know, multiple doctors, multiple MRIs and CT scans and X-rays.

MCCAMMON: Doctors were not able to diagnose a root cause of his illness. Polymeropoulos isn't alone.

Time to get flu shot is now, doctors urge: Or ‘roll the dice’

Flu vaccinations can help reduce the burden on the medical system, experts said

By Kayla Rivas October 1, 2021

The best time to receive a flu shot is now, medical experts told Fox News, after a historic season low last year has left doctors concerned over patients' greater susceptibility to flu-related illness.

Prompt uptake of the flu vaccine can also reduce the burden on the medical system and protect at-risk populations from poor outcomes like hospitalization and death. According to the Centers for Disease Control and Prevention (CDC), everyone 6 months and older should get a flu vaccine every season with rare exceptions.

"It’s perfectly reasonable to get vaccinated right now," Dr. Stanley Deresinski, clinical professor of medicine and infectious diseases at Stanford University, told Fox News, noting the recommendation to get a flu shot extends through the end of October. "You could roll the dice and get it later with the assumption that the flu season is going to come later wherever you are."
