In news Nearly four years ago a mysterious neurological illness, referred to as “Havana syndrome”, started to afflict American diplomats and intelligence operatives in Cuba, China, and other countries.

• Now, a report by the National Academies of Sciences (NAS) has found “directed” microwave radiation to be its “plausible” cause.

What is the ‘Havana syndrome’?

• In late 2016, US diplomats and other employees stationed 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”.

What causes the ‘Havana syndrome’?

• Directed pulsed RF energy appears to be the most plausible mechanism in explaining these cases among those that the committee considered.
• The immediate symptoms that patients reported including sensations of pain and buzzing sound apparently emanated from a particular direction, or occurred in a specific spot in a room.
