What is Havana Syndrome?

Context

  • Nearly four years after a mysterious neurological illness started to affect American diplomats in Cuba, China, and other countries, a report has found “directed” microwave radiation to be its “plausible” cause.

About the Study

  • The researchers have examined four possibilities to explain the symptoms — infection, chemicals, psychological factors and microwave energy.
  • The experts examined the symptoms of about 40 government employees.
  • The report concluded that directed pulsed RF (radio frequency) energy appears to be the most plausible mechanism in explaining these cases among those that the committee considered.

What are ‘microwave weapons’?

  • “Microwave weapons” are supposed to be a type of direct energy weapons, which aim highly focused energy in the form of sonic, laser, or microwaves, at a target.
  • People exposed to high-intensity microwave pulses have reported a clicking or buzzing sound, as if seeming to be coming from within your head.
  • It can have both acute and long-term effects — without leaving signs of physical damage.

The ‘Havana syndrome’

  • In late 2016, US diplomats in Havana reported feeling ill after hearing strange sounds and experiencing odd physical sensations in their hotel rooms or homes.
  • The symptoms included nausea, severe headaches, fatigue, dizziness, sleep problems, and hearing loss, which have since come to be known as “Havana Syndrome”.
  • Cuba had denied any knowledge of the illnesses even though the US had accused it of carrying out “sonic attacks”, leading to an increase in tensions.
