Last month, 50 students and teachers at Lilburn Middle School in Gwinnett County, Ga., a suburb of Atlanta , tested positive for tuberculosis exposure, and four have been confirmed to have an active case of TB.. While that news may be shocking to most, it is nothing new. In October 2009, about 200 students at the county’s Norcross High School underwent testing, after TB was discovered at the school. Of course, Atlanta is a known ‘sanctuary city’ for illegal aliens.It is often said that the flood of illegal immigrants into this country is reaching 'epidemic proportions.' While that statement is true, it is just as true that the illegal immigrants pouring over the U.S./Mexican border are endangering this country with actual epidemics. Tuberculosis, hepatitis, dengue fever, chagas, and even leprosy are being imported into the U.S. inside the bodies of illegal aliens. A virtual 'hot-zone' of disease can be found in this nations border states. Illegal immigrants have set up so-called ;colonias’ just inside the states of New Mexico, Texas, and Arizona. The shanty towns are comprised mostly of cardboard shacks and huts made with cast-off building materials. They have no sanitation, and are surrounded by mounds of garbage. The estimated 185,000 illegals share their makeshift towns with armies of rats. Of course, diseases only common to Central and South America run rampant in these places.
