"For the first time, Havana syndrome has been reported in India after a CIA officer reported symptoms similar to the mysterious illness during his visit to New Delhi earlier this month. The US officer was part of CIA director William Burns' delegation and had to receive medical aid during his stay in India, reports on CNN and NYT said. The development comes weeks after US Vice-President Kamala Harris's visit to Vietnam was delayed when multiple US personnel reported Havana syndrome symptoms just ahead of her trip last month. In July, US diplomats in Vienna, Austria, also reported possible cases of the syndrome.

First reported in Cuba in late 2016, the mysterious neurological illness has afflicted American spies and diplomats in Russia, China, Austria and several other countries. In late 2016, US diplomats and other employees stationed in Cuba's capital, Havana, reported feeling ill after hearing strange sounds and experiencing odd physical sensations in their hotel rooms. The symptoms included nausea, severe headaches, fatigue, dizziness, sleep problems, and hearing loss. This has since come to be known as "Havana syndrome". Since 2016, about 200 US officials and their family members have reportedly experienced symptoms similar to this illness. Some were even left with dizziness and fatigue for months.A 2019 US academic study found "brain abnormalities" in diplomats who had fallen ill.

Five years since being first reported, doctors and scientists are yet to ascertain what causes Havana syndrome. Different theories have done the rounds since then -- from psychological illness to some sort of sonic weapon.However, microwave radiation has emerged to be the "plausible" cause, according to a report by the National Academies of Sciences (NAS)."

"The central government has agreed to investigate the possibility of the presence of the Havana Syndrome in India. The government made a submission to this effect last week in the Karnataka High Court, which was hearing a plea seeking an investigation into the mysterious illness in the country. The petition was filed by A Amarnath Chagu, a resident of Bengaluru, who sought an inquiry into the syndrome in India and measures to prevent its transmission within the country. The Centre's counsel has agreed to examine the matter in a time-bound manner, with the investigation to be completed within three months."
