Query: Influence of State Reopening Policies in COVID-19 Mortality   By the end of May 2020, all states in the US have eased their COVID-19
mitigation measures. Different states adopted markedly different policies and
timing for reopening. An important question remains in how the relaxation of
mitigation measures is related to the number of casualties. To address this
question, we compare the actual data to a hypothetical case in which the
mitigation measures are left intact using a projection of the data from before
mitigation measures were eased. We find that different states have shown
significant differences in the number of deaths, possibly due to their
different policies and reopening schedules. Our study provides a gauge for the
effectiveness of the approaches by different state governments and can serve as
a guide for implementing best policies in the future. It also indicates that
the face mask mandate seems to correlate with the change in the death count
more dramatically than other measures.
