That's good. But since it can take up to 4 months to determine the exact strain of TB, what happens in between diagnosing TB & determining the particular strain of TB? That's what has me shaking my head.
Yeah, that's my concern too...is this infected person cooking my burger at McDonald's or serving on the line in the elementary school cafeteria?
It may be that a skin test is required to START these jobs (and I don't even know that), but what about the ones exposed after the original skin test?
