Fact Sheets
Trends in Tuberculosis, 2006 – United States
Updated: November 2007
How many cases of tuberculosis (TB) were reported in the United
States in 2006?
In total, 13,779 TB cases (a rate of 4.6 cases per 100,000
persons) were reported in the United States in 2006. This represents
a 3.1% decline in the rate from 2005. The 2006 TB rate was the
lowest recorded since national reporting began in 1953.
Is the rate of TB declining in the United States?
Yes. The TB rate is going down in the United States. But, the
decrease in the percent change of the annual case rate has slowed,
from an annual average of 6.6% for 1993 through 2002 to an average
of 3.1% for 2003 through 2006.
How do the rates of TB compare between U.S.-born persons and
foreign-born persons living in the United States?
In 2006, the TB rate in foreign-born persons in the United States
(22.0 cases per 100,000 persons) was 9.5* times greater than that of
U.S.-born persons (2.3 cases per 100,000 persons).
* Ratio calculation is based on unrounded data values.
How many people died from TB in the United States?
There were 646 deaths from TB in 2005, a 1.7% decline from 657
deaths in 2004.
What are the rates of TB for different racial and ethnic
populations†?
- American Indians or Alaska Natives: 7.4 cases per 100,000
persons
- Asians: 25.6 cases per 100,000 persons
- Blacks: 10.2 cases per 100,000 persons
- Native Hawaiians and other Pacific Islanders: 13.6 cases per
100,000 persons
- Hispanics or Latinos: 9.2 cases per 100,000 persons
- Whites: 1.2 cases per 100,000 persons
† For this report, persons identified as white, black, Asian,
American Indian/Alaska Native, native Hawaiian or other Pacific
Islander, or of multiple races are all non-Hispanic. Persons
identified as Hispanic may be of any race.
Is multidrug-resistant tuberculosis (MDR TB) on the rise?
Among all reported TB cases in the United States, the percentage
of multidrug-resistant
(MDR) TB cases in persons with no previous history of TB that
were reported in the United States decreased from 2.4% in 1993 to
approximately 1.1% in 1997, and remained approximately at 1% up to
and including 2006.
Since 1998, the percentage of U.S.-born patients with MDR TB has
remained < 0.7%. However, of the total number of reported primary
MDR TB cases, the proportion occurring in foreign-born persons
increased from 25% (103 of 407) in 1993 to 80% (73 of 91) in 2006.
How are TB data collected?
The 50 states, the District of Columbia, New York City, Puerto
Rico, and seven other U.S. jurisdictions in the Pacific and
Caribbean, report all TB cases to CDC. These cases must meet the
CDC/Council of State and Territorial Epidemiologists
case definition. When cases are reported, the report includes
specific information about the person with TB. This includes the
patient’s race, ethnicity (either Hispanic or non-Hispanic),
treatment information, and, when available, drug-susceptibility test
results. CDC calculates national and state TB rates and rates for
foreign-born, U.S.-born, and racial/ethnic populations. These
calculations use U.S. census population estimates for the years 1993
through 2006.
Where can I find TB data for my state?
The most recent surveillance report, Reported Tuberculosis in the
United States, 2006, has TB data from reporting areas. If you need
additional state-specific data not available in this report, you can
contact your state TB control office.
