My wife had a near miss on mass TB testing when she was a school nurse. A Bosnian refugee student in her school had a positive reaction to a TB skin test. It took a lot of work with interpreters to convince the kid’s parents to allow a chest X-ray. Fortunately his chest X-ray was negative and it turns out that he was immunized at a refugee camp with a BCG TB vaccine which would give him a permanent positive reaction to a TB skin test. Another area school was not so lucky and had to do mass TB screenings and several students and faculty were required to take anti-TB medications for a year. Coming soon to your local schools thanks to Obama.
When I was in grade school (and even later) all the kids were routinely tested for TB.
My father died of TB 77 years ago when I was 5 years old and I still test positive on the tine test yet never had the disease.
