Before revision:  Due to the sparsity of the  mobility matrix,  epidemics tend to develop independently in different regions . Finally , we show how disregarding the specific structure of social contacts could lead to severe underestimation of post-lockdown effects, while specific age cohort based measures can sustain the mitigation of rebound effects.
After revision:  Due to the sparsity of the mobility matrix, epidemics tend to develop independently across areas, justifying the adoption of solutions specific to individual regions or to clusters of regions. Second , we show how disregarding the specific structure of social contacts could lead to severe underestimation of post-lockdown effects, while specific age cohort based measures can sustain the mitigation of rebound effects.
