| Slide 8. TB Case Rates by
Race/Ethnicity, United States, 1993–2007. This slide shows the
declining trend in TB rates by race/ethnicity during the last 15
years. Asians and Pacific Islanders had the highest TB rates, which
declined from 44.1 per 100,000 in 1993 to 26.2 in 2007, and had the
smallest percentage decline over the time period (41%). Rates
declined by approximately 50% or more over the time period in the
other racial/ethnic groups: among non-Hispanic blacks or
African-Americans, from 28.5 in 1993 to 9.4 in 2007; among
Hispanics, from 19.9 to 8.5; among American Indians and Alaska
Natives, from 13.9 to 5.9; and among non-Hispanic whites, from 3.6
to 1.1. Since 2003, the Asian and Pacific Islander race category has
included persons who reported race as either 1) Asian only or 2)
Native Hawaiian or Other Pacific Islander only. Although these
categories were reported separately beginning in 2003, they were
merged for this slide to allow for continuity in reporting trends. Several important factors likely contribute to the disproportionate burden of TB in minorities. In persons who were born in countries where TB is common, TB disease may result from infection acquired in the country of origin. Unequal distribution of TB risk factors, such as HIV infection, may also contribute to increased exposure to TB or to an increased risk of developing TB once infected with M. tuberculosis.
