Tuberculosis Home > Tuberculosis Statistics in the United States

In the United States, tuberculosis statistics indicate that although the overall rate of new cases is still declining, the annual decrease in tuberculosis cases has slowed dramatically in recent years. Several factors may have triggered this trend, including the HIV epidemic, immigration, and increased poverty.

Recent Trends in Tuberculosis Statistics in the United States

In 2005, the Centers for Disease Control and Prevention (CDC) reported 14,093 cases of active tuberculosis (TB) in the United States.
 
While the overall rate of new tuberculosis cases continues to decline in the United States since national reporting began in 1953, the annual decrease in tuberculosis cases has slowed from an average of 7.1 percent (1993 to 2000) to the current average of 3.8 percent (2001-2005), according to CDC.
 
In addition to those with active tuberculosis, an estimated 10 to 15 million people in the United States have latent tuberculosis. On average, about 10 percent of these infected individuals will develop active tuberculosis at some point in their lives. Some underlying conditions increase the risk of latent TB infection progressing to active TB disease -- the risk can be 3 times higher (as with diabetes) to more than 100 times higher (as with HIV infection).
 

Minorities and Tuberculosis Statistics in the United States

Minorities are affected disproportionately by tuberculosis, which occurs among foreign-born individuals nearly nine times as frequently as among people born in the United States. This is partially because they were often exposed to M. tuberculosis in their country of origin before moving to the United States. In 2004, a very high percentage of Asians (95 percent) and Hispanics (75 percent) who were born outside the United States were reported to have tuberculosis.
