The incidence rate of tuberculosis in the U.S. in 2014 was 3.0 per 100,000 population, representing a 2.2% drop since 2013, according to an MMWR article. However, this decline was the smallest in over a decade.

Among the other findings for 2014, from the CDC’s National Tuberculosis Surveillance System:

• The TB rate among foreign-born individuals was 13 times higher than that among U.S.-born people.
• Asians continued to have the highest rate, at 18 per 100,000. Whites had the lowest rate (0.6/100,000).
• Four states accounted for 50% of cases: California, Florida, New York, and Texas.
• Among the 86% with known HIV status, 6% were positive for HIV infection.

The authors emphasize the need to identify and treat all those with latent TB among high-risk groups in the U.S, such as the foreign-born. They add that “priority should be placed on those at highest risk for reactivation,” including those from sub-Saharan Africa or Southeast Asia.
