Between 2012 and 2015, 1,565 refugees were diagnosed with active tuberculosis (TB) in the United States, according to annual reports published by the Centers for Disease Control (CDC).
The CDC data, which has been public but obscure until now, shows that the number of refugees diagnosed with active TB in recent years is more than three times greater than previously reported by any media outlet.
The number of refugees diagnosed with TB in the United States has increased every year since 2012, the first year the CDC began publishing data on foreign-born cases of the disease by category, when 358 were diagnosed. In 2013, 396 refugees were diagnosed with TB. The following year, 2014, 402 refugees were diagnosed with TB, and in 2015, the number of refugees diagnosed with TB rose again to 409. Data for 2016 has not yet been reported.
Foreign-born TB cases as a percentage of all TB cases diagnosed in the United States increased from 63.1 percent in 2012 to 66.4 percent in 2015.
