Yesterday, I was looking at some teen volunteer opportunities for my daughter to do this summer and noticed one required a TB skin test (at our zoo). She is deathly afraid of needles and loves animals, so we might have to force her to get this so she can volunteer.
Anyway, I was thinking about them in general and began to wonder, why do we still need these? I know TB is a bad disease and that is becoming more prevelent than in the recent past. I also know there are some resistant strains coming along. BUT there are all kinds of bad bugs out there and we don't get tested for those.
Is TB skin testing one of those old requirments that is now a little outdated? Doe is really prevent anything?
