title: Foreign-born persons with tuberculosis in the United States.
abstract: Two recent surveys of selected states and cities suggest that foreign-born persons account for approximately 15 per cent of the new cases of tuberculosis reported annually in the areas surveyed. In both surveys the largest number of foreign-born persons came from the Western Hemisphere, the next largest from Asia. The largest number of foreign-born persons with tuberculosis are in the 15-29 year age group, presumably because most entering aliens are in this age group. Among persons with tuberculosis, a larger per cent of foreign-born patients have extrapulmonary disease than do native-born patients. About 50 per cent of the foreign-born persons with tuberculosis entered the United States within the five years prior to onset of disease. Within the United States, significant inter-area variation exists in the proportion of persons with tuberculosis who are foreign-born and in countries of origin of these persons.
