I set my PC to get HST1 this morning, but only recently started getting some. They say these WUs are only available in limited quantities.
This project hits close to home.
My wife, who is Korean, had a little bit of TB when she was younger. This was confirmed about 42 years ago -- a few years after we got married. I was stationed in Italy, and she applied for a food-worker position. At that time, they required a chest X-ray for that position, and she had some calcified nodes in her lungs (her body had successfully fought the disease and isolated it in those nodes).
Yes, she was allowed to work in that position.
