In news- Recently US Vice-President Kamala Harris’ trip from Singapore to Vietnam was delayed due to Havana syndrome.
About the syndrome-
- Havana syndrome was first detected in 2016 among spies and diplomats working at the American embassy in Havana.
- Several US spies and diplomats have been severely affected by the syndrome since then, with some complaining that they even retired from their jobs due to this “illness”.
- These “unexplained health ailments” have been reported by Americans serving in other countries, including Germany, Austria, Russia and China.
- A person suffering from Havana syndrome exhibits a range of symptoms including nausea, hearing loss, memory loss, dizziness and tinnitus.
- Some of those have also reported hearing a loud piercing sound and feeling intense pressure in the face.
- When the brains of some affected people were scanned, the diagnosis revealed tissue damage similar to the one caused by a car accident or a bomb blast.
- The real cause for Havana syndrome has not been ascertained yet.
- In December 2020, a report by the National Academies of Sciences (NAS) was published by researchers that revealed directed and pulsed radio frequency energy as the most “plausible” cause for this syndrome.
- Some researchers have also considered microwave weapons to be “a main suspect” for the syndrome.
