The first two cases of Covid-19 in Italy were detected and isolated in Rome on January 31, 2020. On February 21, a new cluster was detected in Lombardy, which would soon become one of the worst hit regions in Europe. On March 7, Italian Prime Minister Giuseppe Conte imposed a first lockdown in the north, subsequently extended to the entire nation with increasingly restrictive measures, such as the closure of most businesses, social distancing, the obligation to wear gloves and masks, and, at the height of the pandemic, a ban on walking or exercising more than 200m (656ft) from home. People could go out exclusively for essentials and to walk their dogs. Queues outside supermarkets in Milan easily reached one hour. Since May, as the number of active cases began to fall, the ban was lifted, and bars, restaurants, hairdressers, museums, libraries, shops, churches, and cinemas, have been allowed to reopen in phases. Face masks are still mandatory in indoor public spaces.
