RE:RE:RE:RE:RE:Stagezero begins COVID-19 testing for travel to China $$$$$$You would think that it would be the same as once you go through the checkpoints [ scanners and sensor devises ] then you enter the security zone [ boarding gates and what not ] it should apply to the COVID testing and of course if you leave this zone you have to get tested again , but thats where the test kits come into play.
