That is a relatively small number.
All I know is that when I travel abroad, I get a bunch of vaccinations renewed, even if it is to a first world country.
Which is what I find disturbing about the argument that illegal immigration is to blame. Sure it is, in some cases, but not in others . . . so is someone truly concerned about health risk, or illegal immigration? And if someone engages in that argument (and including legal immigration), how is it different from a lib taking the opportunity to scream, "ban guns," whenever there is a crime?
I don't think that even some opponents of illegal immigration (and I oppose illegal immigration) understand that they are hurting the cause.
Give it another couple months, and we'll get a "bubonic plague reported in Arizona" thread, with people blaming it on everything but where it originates, mouse crap.
