U.S. tuberculosis cases decreased in 2010

According to the Centers for Disease Control and Prevention, there were 3.9 percent fewer cases of tuberculosis in the United States in 2010 than in 2009.

The authors of the CDC study point out that although the average drop in TB rates was 3.8 percent per year during 2000 to 2008, the target of 0.1 case per 100,000 people was not actually met in 2010. In 2010 there were 3.6 cases for every 100,000 people, according to

TB rates in the United States were found to be 11 times greater in those that were foreign-born than in those born in the United States.

In comparison with non-Hispanic caucasians, Hispanics had TB rates seven times greater. Non-Hispanic African-Americans had TB rates eight times greater than whites and Asians - 25 times greater - reports. Of those recently born in the United States, African-Americans are seven times as likely to develop TB as caucasians, according to the report.

The report maintains that in order to address these disparities among foreign and U.S.-born individuals and American ethnic groups, surveillance and TB control will need to persist in the long-term.

All of the health departments in the United States are required to report confirmed TB cases to the CDC. The reports include details of the patient’s self-identified race, ethnicity, treatment data and drug susceptibility test results, reports. The CDC gathers this data, along with data from the U.S. Census population estimates, to determine overall TB rates in the country.

The TB rate among U.S.-born individuals dropped 3.4 percent from 2009 to 2010. The rate among the foreign-born population is 18.1 per 100,000 people. Approximately half of all foreign born cases came from four countries - Vietnam, India, the Philippines and Mexico.

There were 113 cases of multi-drug resistant TB in 2009.
