A study carried out among 2'766 people by the University Hospitals of Geneva (HUG), the Geneva Centre for Emerging Viral Diseases, and the University of Geneva (UNIGE), Switzerland, reveals that, at the time of the decline of the Coronavirus pandemic, only 10.8% of the Geneva population had been infected with Covid-19. Moreover, compared to adults between 20 and 50 years of age, children between 5 and 9 years of age are three times less likely to be infected and those over 65 years of age half as likely. These results were published in the Lancet.
