“TB disease in the United States is most common among people who travel to or who were born in countries with high rates of TB.

• In 2017, a total of 70.1% of reported TB cases in the United States occurred among non-U.S.-born persons.
• The case rate among non-U.S.–born persons (14.7 cases per 100,000 persons) was approximately 15 times higher than among U.S.-born persons (1.0 cases per 100,000 persons).
• The percentage of U.S. TB cases among non-U.S.–born persons who have been in the United States for 10 years or longer are about equal to those who have been in the United States less than 10 years.”
