As with every other illness, soap and water are the first step to good health. Currently there is immigrations occurring worldwide in numbers never before seen. Many Third World immigrants move into countries we consider 2nd class or 1st class but bring 3rd class habits with them.
Many of these people work in service type positions to take care of us ist class people and they do bring their poor health habits and infections with them.
Hire a maid or a baby sitter from the mountains of Pakistan, the hills of Uraguay, Guatamala or Mexico and guess what you have opened your home to. Someone with a much stronger immune system than you have who will survive diseases that will kill you.
Open borders along with Catch and Release of OTM's (Other than Mexicans) only furthers this problem.
Thank you, Mr. President for your open stance on immigration control.
Sometimes I don't even like to touch the railing in the subway in Manhattan :( Not to mention all the spitting that goes on right on the street. TB is making a big comeback and I guess it doesn't matter in the light of cheap labor.
