What is Havana Syndrome?

The mystery illness got its name after dozens of diplomats at the US embassy in the Cuban capital complained of sickness, including migraine headaches, dizziness and memory lapse in 2016.

Thousands of Cubans demanded on social networks the reopening of consular services at the United States Embassy in Havana, paralyzed in 2017 by then-US President Donald Trump.  It all started early in the day, when more than a dozen Cubans personally went to the North American legation in Havana to denounce that their procedures have been in limbo for four years and they have not been able to meet with their relatives in the United States.
