I believe the poster was claiming that the Mexicans come in with infectious disease. If they had also been consuming available antibiotics while ill in Mexico, couldn’t they be bringing in mutated bacterial infections? Just being prescribed ineffective meds could breed resistance.
I know not all disease remains infectious over a long period of time. I’m not blaming Mexicans, as I live in an area with very few illegals. The farm workers I know of are hired through a rigorous program that includes health evaluations and checks on both sides of the border, much at the employers’ expense. But it obviously is different in border areas.
I didn’t even touch on the drugs that enter municipal water systems. There are a lot of ways uncontrolled immigration can spread resistant illness.
MSRA is a different animal, altogether. And the fact that we are dealing with it here should be an indication that it was born here.
Tain't just Mexicans. It is illegal immigrants in general. Diseases which were once virtually eradicated by vaccinations and quarantines in the US have been re-imported into a population that has NOT been vaccinated, having been born after the illness were understood to have been eradicated. Little things like "tuberculosis".
Add to that little inconveniences like bed-bugs, virtually unheard of in the USA over my entire lifetime, and which are now spreading like plague.
