Fact is, immigrants and illegal invaders are bringing all kinds of disease to the USA.
The measles outbreak is due to multiple immigrants bringing it here from several countries. Ebola will come soon enough. I expect the USA and Europe to get hit this year at some point. People with money are escaping from the Congo.
I was on a flight in 1980, traveling from Houston, TX to Tampa, FL. The jet was stopped out in the middle of nowhere, people boarded the plane from the rear, and everyone was asked to provide their contact info for the next 72 hours. They told us nothing. And they hauled the family that sat in the entire row behind me off the plane. They were Asian.
My wife was 5 months pregnant, and I did not want to go near her until I find out what I may have been exposed to, so I go to the airport manager's office. He was unaware a jet was boarded in his airport! So, we call the Dept of Health, and this doctor tells me, do not repeat what I am about to tell you out loud. He informs me the family taken off the jet were from Laos, tested when they hit the west coast and permitted to travel on through the USA. They tested positive for cholera! This doctor said I as long as I did not have physical contact with them, I should be fine.
So allowing diseased people the freedom to travel this nation with deadly diseases has been going on for some time. The government just does not care about the welfare of the citizenry any longer. I have often said we are becoming more like Russia and it is true. In Russia, the entire population is expendable to the dictator Putin. So too our population is being treated as if we are all expendable.
