Despite declining numbers of US tuberculosis (TB) cases, the mycobacterial illness continues to disproportionately affect foreign-born residents and certain racial and ethnic populations.
A recent analysis showed 9588 new TB cases were reported in the United States last year, a 4.2% decrease from 2012. The data, taken from state health departments and the US Census Bureau, show that 6172, or 64.6%, of those cases were among residents from other countries. Among those whose national origin was known, 54.2% were from Mexico, the Philippines, India, Vietnam, or China (Alami NN et al. MMWR Morb Mortal Wkly Rep. 2014;63:229-233).
