Of course if you read the actual article (Which I suspect you didn’t) your addition to the headline is silly.
The best hypothesis is that it is related to constant, repeated dehydration. Not a mention of infectious disease in the article.
The desperate attempts to link disease to illegal immigration are getting a bit ridiculous.
1) Any virulent new virus is going to spread much more rapidly through legal air travel than illegal immigrants walking across the border.
2) Every time there is a thread on drug-resistant infections, people desperately try to link it to illegal immigrants, when, actually, they are a result of ADVANCED health care in the US and Western Europe - you need to actually use advanced antibiotics on people for the bacteria to evolve resistance to them.
Get a frickin' life, it is obvious he didn't mean the remark to be taken seriously, it is a spoof at the left who are always using something to scare us with. At least that is how I took it, especially after reading the article. FReepers use Paras to modify(if you want to call it that, I call it making a comment on the title)the title, it is done all the time and for you to mention it at all puts you in the posting police category, IMO. Some one who can't help but criticize those who do things not to your liking.
