The Rising Influence of Rising Affluence

I am still trying to figure out if airlines (ships etc.) could get a reliable test to give to passengers before they board to screen them to validate a risk free virus environment in the cabin and boarding areas?. Dr. Fauci mentioned there is no such thing as asymptomatic, so seems a bunch of stuff surrounding duration of virus contagion and the ability to confirm exact timing of a diagnosis is still up in the air?
