@Mr_Inquisitr @drensber @ann_mcnitt @ignorantprophet @ayshakhoury @CIDRAP They're averages. Sometimes infections happen with much shorter exposure, sometimes no infection despite longer exposure. Also does not account for ventilation or distance.
Distance on transit is often VERY close, so likely faster than these "average" exposures.
@调查官先生@drensber@ann_mcnitt@ignorantprophet@ayshakhoury@CIDRAP他们是平均数。有时感染发生在接触时间短得多的情况下，有时即使接触时间长也不会感染。也不考虑通风或距离。
在运输途中的距离通常非常近，因此可能比这些“平均”暴露速度更快。
