TB Case Rates by Race/Ethnicity
United States, 1991-2001

Tuberculosis in the United States
Slide 8: TB Case Rates by Race/Ethnicity, United States, 1991-2001. This slide shows the declining trend in TB case rates by race/ethnicity during the last decade. Asians and Pacific Islanders had the highest TB case rates, which declined from 44 per 100,000 in 1991 to 33 in 2001. Non-Hispanic blacks had the most substantial decline from 32 in 1991 to 14 in 2001. Case rates declined among Hispanics from 23 in 1991 to 12 in 2001, among American Indians and Alaska Natives from 19 to 11, and among non-Hispanic whites from 4 to 2. Several important factors likely contribute to the disproportionate burden of TB in minorities. In foreign-born persons from countries where TB is common, active TB disease may result from infection acquired in the country of origin. In racial and ethnic minorities, 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 active TB once infected with M. tuberculosis. However, much of the increased risk of TB in minorities has been linked to lower socioeconomic status and the effects of crowding, particularly among U.S.-born persons.
