As tuberculosis declines among the native-born, it's growing among immigrants, who now make up a majority of cases nationwide. The Washington Post report contains the obligatory disclaimer:
"We recognize national borders but microbes, including TB, don't," Cain said. "As long as TB is out of control globally, as it is, this will be a problem in the U.S. If you breathe, you're at risk for TB. This can affect anyone."
But since TB is on the decline among natives and, as the article itself points out, the immigrant cases are disproportionately found among immigrants from Southeast Asian and sub-Saharan Africa, then borders really do matter after all.
