Covid-19 pandemic hit very harshly Italy in two waves: the first can be temporally placed in spring and the second between autumn and winter. Data shows some relevant differences among the two phases, in particular, the first wave caused less infection but with a higher lethality rate. These differences in epidemic and social conditions in the two phases suggested a change in the strategy of containment measures: stricter and homogeneous in the first wave, flexible and diversified in the second wave. The interrupted analysis applied to daily data of new infected shows positive results for both interventions in flattening the infection curve. Both policies achieved almost the same percentage of positives cases avoided. For this reason, these measures seem rightly tuned, in both cases, to the specific epidemic and social conditions of each wave.

Abstract
Covid-19 pandemic hit very harshly Italy in two waves: the first can be temporally placed in spring and the second between autumn and winter. Data shows some relevant differences among the two phases, in particular, the first wave caused less infection but with a higher lethality rate. These differences in epidemic and social conditions in the two phases suggested a change in the strategy of containment measures: stricter and homogeneous in the first wave, flexible and diversified in the second wave. The interrupted analysis applied to daily data of new infected shows positive results for both interventions in flattening the infection curve. Both policies achieved almost the same percentage of positives cases avoided. For this reason, these measures seem rightly tuned, in both cases, to the specific epidemic and social conditions of each wave.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
