The Havana syndrome has been causing problems around US embassies for the past five years. At least 130 people are now dealing with the consequences of the mysterious disease.
It concerns sixty cases in China and Cuba and another 70 patients in Europe and Asia. The disease first showed up among US embassy personnel in Cuba, hence the name Havana syndrome. They suffered from unexplained complaints, such as severe headaches and nausea. They also heard strange noises.
At first it was thought that these were secret attacks with sound and radio waves, but last year it was concluded that microwaves are likely to cause the complaints. US President Joe Biden has pledged to investigate the disease further.
