You are potentially infecting ALL the people on the Greyhound. If you take a Greyhound 10 miles you are potentially infecting ALL the people on the Greyhound. The Greyhound is not spraying the surroundings with germs as it goes.
If your rich yuppie spends 8 hours on an airliner going x miles or 16 hours on an airliner going 2x miles, he is not spreading any more germs in the latter instance. Fewer in fact, because he has less time OFF the airliner in which to spread more germs.
But really, this is just another distraction. The truth of it is someone made an idiotic prejudiced statement and now you guys are spinning madly to try to avoid admitting that it was an idiotic prejudiced statement. That's all.
U.S. border security scrutinized after TB patient slips in
A senior House member wants to know how a dangerously infected man managed to get through U.S. Customs and Border Protection even though his passport had been flagged in their computer system.
Andrew Speaker, an Atlanta, Georgia, personal-injury lawyer infected with extremely drug-resistant tuberculosis, flew from Europe into Canada to avoid a no-fly order in the United States. His passport was checked at the U.S.-Canada border, a Homeland Security official told CNN.
An alert that Speaker should be detained and isolated, and public health officials should be contacted, showed up on the Customs and Border Protection computer system, but he was allowed to cross into the United States at Champlain, New York, anyway, the official said.
Speaker was at the border crossing for less than two minutes.
