Rat out of a cage
I agree with your premise but TB is not easy to catch unless your immune system is suppressed.Let's be honest tb is back because immigrants legal and illegal don't trust the vaccines. Anything that happened when you grew up has no relevance in why we are seeing a resurgence in many diseases that people from third world countries have. although now they have turned parts of our country into third wold like areas.
As an older person with a chronic disease, I am very careful and get tested yearly for TB and other "lung" type diseases. I am susceptible to bronchitis as well as Guillain-Barré syndrome so it ties right in with TB.
