Dengue fever is from mosquitos, and the thriving of mosquitos is from the outlawing of DDT. An illegal immigrant infected with Dengue fever cannot spread the disease because Dengue IS NOT CONTAGIOUS.
You could get rid of every illegal immigrant in the U.S. and there'd still be a Dengue epidemic if Dengue-carrying mosquitos are present. Dengue is spread by mosquitos, not illegal immigrants.
And I suppose that the mosquitoes are biting only citizens in order to become Dengue-carrying mosquitoes.
If mosquitoes bite someone without Dengue, they're annoying but not terribly significant when they later bite you. If mosquitoes bite illegals who have Dengue (Look at the map.), the results are far different.
Sory ..its Bush’s fault
