Abstract

The incidence of tuberculosis (TB) has declined steadily in the United States; however, foreign-born persons are disproportionately affected. The aim of our study was to describe characteristics of TB patients diagnosed in the United States who originated from the African continent. Using data from the U.S. National Tuberculosis Surveillance System, we calculated TB case rates and analyzed differences between foreign-born patients from Africa compared with other foreign-born and U.S.-born patients. The 2009 TB case rate among Africans (48.1/100,000) was 3 times as high as among other foreign-born and 27 times as high as among U.S.-born patients. Africans living in the United States have high rates of TB disease; they are more likely to be HIV-positive and to have extrapulmonary TB. Identification and treatment of latent TB infection, HIV testing and treatment, and a high index of suspicion for extrapulmonary TB are needed to better address TB in this population.
