ROME (Reuters) - Italy’s government has approved new restrictions to tackle the second wave of the coronavirus epidemic and curb a steady rise in deaths and hospital admissions.Under previous decrees gyms, cinemas and theatres were already closed and restaurants and bars must shut at 6 p.m. Here are the main new measures that come into force on Friday and are due to run until Dec. 3:The government has established three tiers that split the country’s 20 regions into red (high risk), orange (medium risk) and yellow (low risk) zones. The zoning depends on a variety of factors, including local infection rates and hospital occupancy. Restrictions are calibrated as a result. The red regions facing the toughest restrictions are Lombardy and neighbouring Piedmont in the industrial north, Calabria in Italy’s southern toe and the tiny alpine region of Valle D’Aosta. The orange regions are Puglia in Italy’s mainland heel and the southern island of Sicily. All the remaining regions, including Lazio around the capital Rome, are yellow, meaning there are no restrictions other than those imposed nationwide.
