Upswing? Epidemic? What TB epidemic? The overall number of TB cases in the United States has been halved in the past 10 years. Among the fewer cases we're seeing, it's true that drug-resistance is growing, but we're still talking about fewer TB cases overall.

And that scientific article is hardly the Answer. Consider the situation this way--in the past 10 years, TB has been declining rapidly in the United States, however the decline has been mostly among non-Hispanic whites. That leaves behind other groups who haven't seen much improvement, like foreign-born residents or African-Americans. Suddenly, these other groups stick out like sore thumbs when you look at who is getting TB. Are these groups getting more TB than they did before and fueling this "epidemic"? No, they're getting TB at roughly the same rate as 10 years ago, they just make up a bigger proportion of the smaller overall "pie" of TB cases.
