@kknnaabb @_mbdr_ @ianmSC Of course it does. We don't have terribly good studies on this but a few obvious candidates are level of immunity, weather/climate, density/crowding, other policies, level of testing, high risk industry/workplaces, households size, etc.
@kknnaabb @_mbdr_ @ianmSC 当然可以。我们对此没有非常好的研究，但一些明显的候选者是免疫水平、天气/气候、密度/拥挤、其他政策、测试水平、高风险行业/工作场所、家庭规模等。
