59% of U.S. TB Cases Occur in Foreign-Born, Mainly from Mexico & Philippines

In the United States, the number of TB cases reported in foreign-born persons has remained virtually level, with approximately 7,000 to 8,000 cases reported each year from 1993 to 2008.

But in 2009, the number of cases dropped to 6,854. That same year, cases among U.S.-born persons decreased to 4,571. In 2009, the percentage of TB cases occurring in foreign-born persons was 59% of the national total. Foreign-born Hispanics and Asians together represented 80% of reported TB cases in foreign-born persons, and accounted for 48% of the national total.

The top 12 countries of origin of foreign-born persons with TB in the United States in 2009 were: Mexico, Philippines, Vietnam, India, China, Haiti, Republic of Korea, Guatemala, Peru, El Salvador, Ethiopia, and Honduras.

Although the TB case rate (number of cases per 100,000 population) in the United States has declined annually in both U.S.-born and foreign-born persons, there has been a faster decline among U.S.-born persons (a 77% decrease since 1993) than among foreign-born persons (a 45% decrease since 1993).

To address the high TB case rates among foreign-born persons, CDC is collaborating with other national and international public health organizations to improve screening of immigrants and refugees, test recent arrivals from countries with high rates of TB, and improve TB control activities along the border between the United States and Mexico.
