You mean like having a border patrol which apprehends a majority of them and tests them for Covid before returning 80% of the detainees to Mexico.
You could but you won't, you just make shit up everyday, post articles that say opposite of what you are implying and then go back to your default racism and inbred logic. Didn't liberals steal an election right under Trump's nose, if that's incompetent, what do you call yourself?
Apprehended illegal immigrants on the southern border are the most tested group for Covid in the U.S. Most are not infected with Covid when they cross the border — sadly the majority get infected when they are held in crowded detention facilities— so effectively they caught Covid in the highly infected U.S.
“Apprehended illegal aliens” nice qualifier..... If Covid’s not a problem for those coming from Mexico and places south, your own admission, how are they infecting each other when they are held in detention, separated from everyone else?
