69% of diagnosed TB cases in the U.S were in foreign-born citizens

According to the CDC, 69% of TB cases in 2017 were in foreign-born citizens and that they are 15x more likely to have it than natural born citizens.


In 2017, a total of 9,093 new cases of tuberculosis (TB) were provisionally* reported in the United States, representing an incidence rate of 2.8 cases per 100,000 population. The case count decreased by 1.8% from 2016 to 2017, and the rate declined by 2.5% over the same period. These decreases are consistent with the slight decline in TB seen over the past several years. This report summarizes provisional TB surveillance data reported to CDC’s National Tuberculosis Surveillance System for 2017 and in the last decade. The rate of TB among non–U.S.-born persons in 2017 was 15 times the rate among U.S.-born persons. Among non–U.S.-born persons, the highest TB rate among all racial/ethnic groups was among Asians (27.0 per 100,000 persons), followed by non-Hispanic blacks (blacks; 22.0). Among U.S.-born persons, most TB cases were reported among blacks (37.1%), followed by non-Hispanic whites (whites; 29.5%). Previous studies have shown that the majority of TB cases in the United States are attributed to reactivation of latent TB infection (LTBI).

Here is the country breakdown

Among non–U.S.-born persons, the highest TB rate among all racial/ethnic groups occurred among Asians (27.0 per 100,000 persons), followed by blacks (22.0) (Table 2). As in previous years, in 2017, the top five countries of birth of non–U.S.-born persons with TB were Mexico (1,204; 19.0% of all non–U.S.-born persons with TB), Philippines (783; 12.3%), India (595; 9.4%), Vietnam (526; 8.3%), and China (400; 6.3%). Persons who received a diagnosis of TB ≥10 years after arriving in the United States accounted for 2,854 (45.0%) of all TB cases among non–U.S.-born persons.

As we reported last month 86% of diagnosed TB cases in NYC were foreign-born citizens.
