It's already showing up. Not that it all comes from raw sewage, but third world diseases that have been extinct in the US for a long time. We've had enough cases of whooping cough in NM that the state health office called it a crisis and advised all school age kids to be immunized again.
The scary one is the drug resistant TB. We've had cases of that kind come to NM from Mexico for treatment. That treatment costs $250,000. ($250K) to treat, and guess who's paying for it. We are! They say if we don't treat it those people will die. You can bet if one of us gets it, we'll be paying for it out of our own pocket.
So, when I see GW, Teddy, John or the other traitors pushing their amnesty plan, I want to reach through the screen and choke all of them. LOL Dang these threads make my blood boil. < /rant > Btw, thanks for the ping! :o)
Someone working in the local health department told me many of their TB cases are quarintined in apartments rented by the county because treatment facilities cost more. Rents aren't cheap in this area either. The figure I was given was $1,000 a month. Their food is also paid for and delivered.
