The zoning depends on a raft of factors including local infection rates and hospital occupancy, with restrictions will calibrated accordingly. In the critically affected red zones people will only be allowed to leave their homes for work, health reasons or emergencies and bars, restaurants and most shops will be closed. High school classes and those for the final two years of middle school will be moved online. However, unlike Italy’s national lockdown in the spring, all factories will remain open. “Our intensive care capacity could be exhausted in a matter of weeks, we have to intervene,” Prime Minister Giuseppe Conte said at a news conference to illustrate the package which comes into effect on Friday.
