这是BBC做的视频,图中德国,意大利,英国reopen时都符合日新增小于千分之四的要求(白色虚线),而美国第一个州开始reopen是在4月底,后面两个红点分别是reopen的州达到50%和90%的日期,都早已英国。随之而来的疫情发展从这张图中就很明显了。
While European countries have managed to keep new infections of Covid-19 at bay, by the time most Americans had emerged from lockdown restrictions a second surge in cases was already underway. Were the requirements met to safely reopen and how much testing was actually being done?
