"Full blown hysteria for homeland security reasons over a US personal injury lawyer sneaking back into the country."
If he was a frequent traveler abroad, Mantoux testing would have been routine for him... A chest x-ray would follow a positive Mantoux, with sputum cultures and/or biopsy to determine strain.
But the bottom line on this guy -- if he were contageous, he would NOT be doing tabloid news programs. With active, multi-drug resistant TB, he would be in a large teaching hospital, in isolation, in a negative pressure room, under the strictest resp/droplet precautions... That would be the protocol for active TB. The strain of M.tb has not been disclosed, has it??...
This case, like so many others, is being hyped for the fear factor. What they're not reporting is that TB is on the rise, largely because of unchecked, illegal immigration into the US from high risk nations... Illegal immigration is the TB threat faced by us all, but it goes unreported because "investigative journalism" has gone the way of the dinosaur in the US. As for the southern (open) border, the national security threat is very real.
