I went overseas many years ago and came back with a positive TB test but no symptoms, aka latent TB. I was shocked at how seriously it was taken (I mean, rightfully so, still surprised). If I remember correctly it was a daily pill and a mandatory immovable weekly trip to the state health department office for a checkup/questionnaire. The pill was for 9 months and the questionnaire was for a year. Really wild stuff.
