Prevention of incursion from the rapidly expanding infections from other countries aid the U.S. in combating the spread here, by combating/treating/quarantining those who have it here.... and NOT letting any more “carriers” in our country.
It is a numbers game,and an information— correct information game to help our citizens help themselves. There is a lot— a ton of misinformation being sent out by dem operatives— and it is propaganda. The clinical people are doing their job. Certainly better than in Italy with an open borders PM, which has had 10K proven infections— and....800 deaths. For real. Lot of chinese back and forth to Italy (thanks to the Italian commie party, btw).
