We, who have (imagine!) many meatpacking plants have had outbreaks of whooping cough in schools for the last several years. Hundreds have been sent home, and some schools have canceled classes.
Two years ago, our State epidemiologist actually SAID in the local paper that it was because of un-immunized illegal immigrant teenagers. First, and only time I ever heard THAT...guess she was "taken aside and corrected"...LOL.
Probably why we haven't seen anything about this outbreak in the MSM.
