Sixty-nine percent of all tuberculosis (TB) cases reported in the United States in 2017 were diagnosed in foreign-born residents,according to a report released earlier this month by the Centers for Disease Control.
This was the highest percentage ever, marking a steady three decade rise from 1986, when only 22 percent of all TB cases reported in the United States were diagnosed in foreign born residents. Last year, in 2016, 68 percent of TB cases were foreign-born.
For the country as a whole, the absolute number of TB cases and the rate per 100,000 declined for the second consecutive year.
9,093 cases were reported in 2017, down from 9,272 in 2016.
