Tuberculosis - United States, 1993-2010.

Tuberculosis (TB) is transmitted via the airborne route by person-to-person contact. Although TB is a leading cause of death on a global scale, most cases can be cured with treatment. From 1993 to 2010, the number of TB cases reported in the United States decreased from 25,103 to 11,182. Despite the decrease, TB continues to affect many communities in the United States disproportionately and unequally, especially racial/ethnic minorities and foreign-born persons. TB remains one of many diseases and health conditions with large disparities and inequalities by income, race/ethnicity, educational attainment, and other sociodemographic characteristics.
