About

What is Havana Syndrome?

  • Havana Syndrome refers to a set of mental health symptoms that are said to be experienced by United States intelligence and embassy officials in various countries.
  • It is worth noting that in general, the word ‘syndrome’ simply means a set of symptoms.
  • It does not mean a unique medical condition, but rather a set of symptoms that are usually experienced together whose origins may be difficult to confirm.
  • Involved symptoms:hearing certain sounds without any outside noise, nausea, vertigo and headaches, memory loss and balance issues.
  • The syndrome traces its roots to Cuba in late 2016.

What are the causes of Havana Syndrome?

  • No one is entirely sure.
  • But initially during the Cuban experience, being in a country that had been hostile to the US for over five decades, the suspicion was on Cuban intelligence or a section within the Cuban establishment that did not want US-Cuba relations to normalise.
  • It was then speculated to be a “sonic attack”.

About Sonic attack

  • Sonic attacks are created by “long-range acoustic devices” that are often used over the open water, where they can be unleashed across greater distances without losing volume.
  • They can result in hearing loss or brain damage.
  • However, further study by scientists in the US and medical examination of the victims began to suggest that they may have been subjected to high-powered microwaves that either damaged or interfered with the nervous system.

Microwaves Weapon

  • Greater exposure to high-powered microwaves is said not only to interfere with the body’s sense of balance but also to impact memory and cause permanent brain damage.
  • Low levels of microwaves are also emitted from mobile phones but they are not targeted.

However, there are no conclusive evidence.
