Several Italian towns are under lockdown to contain the COVID-19 outbreak. The level of transmission reduction required for physical distancing interventions to mitigate the epidemic is a crucial question. We show that very high adherence to community quarantine (total stay-home policy) and a small household size is necessary for curbing the outbreak in a locked-down town. The larger the household size and amount of time in the public, the longer the lockdown period needed.
意大利的几个城镇已经封锁,以控制 COVID-19 的爆发。为了减轻疫情,物理隔离干预措施所需的传播减少程度是一个关键问题。我们表明,要想在封锁的城镇中控制疫情,必须非常严格地遵守社区隔离(全面居家政策)和保持小家庭规模。家庭规模越大,在公共场所的时间越长,就需要更长的封锁时间。
