The classificatons are made based on the coronavirus situaton locally according to a weekly analysis of each region's weekly health data by the health ministry together with the Higher Health Institure (ISS).
People in the highest-risk zones are told to stay within their comune, or municipality, and are only allowed to leave for work, study, health or other essential reasons.
This week, the data showed a another decrease in the incidence of Covid cases overall nationwide over the last 14 days.
These data “are encouraging and confirm the effects of the (government's anti-coronavirus) measures,” the ISS weekly monitoring report stated, however it noted that “the pressure on hospital services is still very high”.
On December 1st, 18 regions reported having exceeded critical thresholds in hospitals or intensive care units, the report said.
“In five weeks we went from a very worrying Rt number of 1.7 to a figure of 0.91,” Health Minister Roberto Speranza told Italian newspaper Il Sole 24 Ore on Friday evening. “This does not mean a narrow escape, but it means that the measures have produced effects.”
“The objective of the government and the regions was to go below 1, we finally succeeded, but there is still a very difficult game in progress”.
The announcement of the latest changes to the tier system came a day after the government announced a new set of restrictions under the latest emergency decree, which is in force from December 4th to January 15th.
It included further travel restrictions throughout December, as the government aims to discourage trips, gatherings and parties over the festive period.
Under its latest emergency decree, the Italian government will require EU citizens to take a coronavirus test before travelling to Italy between December 10th-20th.
