Source-This post on Havana syndrome is based on the article “What is ‘Havana syndrome’, linked to a Russian intelligence unit?” published in “The Indian Express” on 2nd April 2024.
Why in the News?
Recently, Russia dismissed claims from a joint media investigation linking a Russian military intelligence unit to the ‘Havana syndrome’ which affected US diplomats and spies globally.
What is Havana syndrome?
About– It is a term used to describe a set of mental health symptoms reportedly experienced by US intelligence and embassy personnel in different countries.
| History of origin 1. In late 2016, American diplomats and other personnel stationed in Havana reported feeling unwell after encountering peculiar sounds and experiencing unusual physical sensations. 2. These symptoms, including nausea, intense headaches, fatigue, dizziness, sleep disturbances, and hearing impairment, have since been labeled as “Havana Syndrome.” |
What are its causes?
1. Initial speculation leaned towards a sonic attack by Cuban intelligence, but later the National Academy of Sciences suggested that pulsed microwaves could be responsible for these symptoms.
2. Microwaves, a type of electromagnetic radiation with frequencies between 300 megahertz (MHz) and 300 gigahertz (GHz), might have affected victims’ nervous systems.
3. There are suspicions of high-powered microwaves being delivered via a “microwave weapon.”
Note– Microwave weapons are a form of direct energy weapons. They employ beams of high-frequency electromagnetic radiation to heat the water in a person’s skin, causing pain and discomfort.
Havana Syndrome in India
In India, the first case was reported in 2021 when a US intelligence officer travelling to New Delhi with a CIA director reported its symptoms.
