The TB that is seen now is almost completely untreatable, except for removal of the affected lung area. Countries that sell drugs freely to the public have the largest population of TDRT. According to the WHO (World Health Organization) a person dies of Tuberculosis every 20 seconds–that is 3 people per minute. It is highly contagious and airborne.
I remember when I was in my late teens and I had to go get a chest x-ray at the Health Dept. to show that I did not have Tuberculosis, before I could get a job serving sandwiches at a local restaurant. Now protecting your privacy is more important than spreading disease.
When you check into a hotel, or go to attend a convention, how many times do you get tired, worn out, have a headache, stomach problems, diarrhea, flu-like symptoms, etc? Could it be that you are so oxygen deficient that you cannot get enough oxygen when you are there for days at a time, over a week end or on vacation, that you are becoming sick from the DEAD AIR? Plus you are exposed to so many super germs from fellow travelers that your system is overwhelmed.
When a large building is built, the air that is in that structure is trapped inside the outer walls and gets re-circulated year after year. The same scenario takes place in airports, terminals, airplanes and many public spaces where there is little to no exchange of new, outside air coming into the building or structure. The managers of these structures do not want to let cool air out, bring hot air inside, cool the hot air and pay the utility bills to get the air comfortable again. The same scenario takes place when the weather is cold, they heat up the inside air, circulate it, and just recycle it over and over, year after year. They don’t want to pay the utility bills to release “dead used air” that may be oxygen deficient and vent it outside and bring in fresh air that they have to heat to make it comfortable.
The bottom line is that the older the building is, the bigger it is, the fewer accesses to outside air the more oxygen depleted that air is going to become as time goes by. The issue of buildup of bacteria in the air vents and the possibility of creating “super germs” from diseases brought in by sick people is the flip side of this equation. Hospitals are even more at risk of both of these situations due to the health issues of the people who come to the hospital being carriers of illnesses and diseases.
Someday the idea of trapping contaminated, oxygen deficient air in a public building where people will be exposed and have to survive the lack of oxygen will be examined. I hope so, anyway.
