Trends in tuberculosis--United States, 2005.
For 2005, a total of 14,093 tuberculosis (TB) cases (4.8 cases per 100,000 population) were reported in the United States, representing a 3.8% decline in the rate from 2004. This report summarizes provisional 2005 data from the national TB surveillance system and describes trends since 1993. The findings indicate that although the 2005 TB rate was the lowest recorded since national reporting began in 1953, the decline has slowed from an average of 7.1% per year (1993-2000) to an average of 3.8% per year (2001-2005). In 2005, the TB rate in foreign-born persons in the United States was 8.7 times that of U.S.-born persons. In addition, Hispanics, blacks, and Asians had TB rates 7.3, 8.3, and 19.6 times higher than whites, respectively. Moreover, the number of multidrug-resistant (MDR) TB cases in the United States increased 13.3%, with 128 cases (up from 113 in 2003) of MDR TB in 2004, the most recent year for which complete drug-susceptibility data are available. The deceleration of the decline in the overall national TB rate, the persistent disparities in TB rates between U.S.-born and foreign-born persons and between whites and racial/ethnic minorities, and the increase in MDR TB cases all threaten progress toward the goal of TB elimination in the United States. Effective TB control and prevention in the United States require sufficient resources, continued collaborative measures with other countries to reduce TB globally, and interventions targeted to U.S. populations with the highest TB rates.
