为应对第二波COVID-19疫情，意大利政府采取了一项按地区实施的三套限制措施（分别为黄色、橙子和红色）。我们估计，在风险较低的地区（黄色），较温和的限制导致传播率降低约18%，导致生殖数Rt约为0.99。更强的测量（橙子和红色）分别导致降低34%和45%，并且Rt值分别为约0.89和0.77。
To counter the second COVID-19 wave, the Italian government has adopted a scheme of three sets of restrictions (coded as yellow, orange, and red) imposed on a regional basis. We estimate that milder restrictions in regions at lower risk (yellow) resulted in a transmissibility reduction of about 18%, leading to a reproduction number Rt of about 0.99. Stricter measures (orange and red) led to reductions of 34% and 45% and Rt values of about 0.89 and 0.77 respectively.
