Before we jump off the deep end, yes...let's compare statistics. But the comparison should be how many more infections are caught when comparing to 1, 2, or 3 day periods for testing [before embarkation]. That would be the TRUE science [just statistics is what they call SCIENCE these days], and not just irrationally dictating smaller and smaller time periods for testing that are already wholly cumbersome, expensive, and scaring away bookings due to the HORRIBLE stress that's caused. PERFECT testing would be just minutes prior to boarding, but would that really result in enough 'catches' of the virus to make it practical? Practicality has to be balanced with necessity here; and too often we are seeing necessity being outlandishly proposed by knee jerk thinkers who do not consider the practical, emotional, and resource considerations. What's real and what's imagined? So far, cruise industry has proved itself to be the safest form of travel with protocols far and away better than other modes of travel. But there is a cost; so let's not get too ridiculous due to how afraid authorities might want to make us [for what is now looking like just another form of the common cold...or so we hope anyway].
