A 32-year-old Genevan woman died of coronavirus, the first victim of the epidemic in Geneva.
The cantonal doctor confirmed this on Friday, while specifying that this young woman, who died at home, suffered from other illnesses. The diagnosis could not be made until after her death.
According to our sources, the victim was previously tested three times negatively. We also learned that criminal proceedings had been opened by the Public Prosecutor's Office to determine the circumstances of this death and of possible negligence.

According to other reports, a 26-year-old young man is currently in intensive care at the Geneva University Hospitals (HUG) in serious condition, after having passed through the Hospital of La Tour. He too would have initially tested negative for the coronavirus. The authorities do not confirm this: "You should rather ask yourself if people were suffering from the disease when the tests were done," replies the cantonal doctor, Jacques-André Romand.

Professor Didier Pittet, WHO Special Advisor and person responsible for the control and prevention of HUG infection, is trying to raise awareness among young people through an information campaign. "Teens and young adults absolutely do not respect the rules of hygiene and social distance. They go out to bars, do not observe any distance between them, kiss each other ... and spread the virus! They think, wrongly, that this is something of old people." However, if the majority passes between the drops of the epidemic, "as we have seen in China and in Italy, young healthy people develop dramatic infections and die, after being exposed to a high quantity of virus". An amount released after someone sneezes you in the face, for example.
