In February 2020, the COVID-19 pandemic was confirmed to have spread to northern Italian regions. In a few weeks, it spread to the rest of the country, with major concentration of cases in the regions of Lombardy, Emilia-Romagna, Piedmont and Veneto. The government faced the subsequent health crisis by imposing gradually stricter measures of social distancing and quarantine, until finally on 9 March established a nationwide lockdown, restricting the movement of people except for reasons of necessity, health, or work.[40][41]
