Tuberculosis in the United States
Slide 20: Primary Isoniazid Resistance in U.S.-born vs. Foreign-born Persons, United States, 1993-2001. This graph shows primary isoniazid resistance in U.S.-born vs. foreign-born persons. Among foreign-born persons, the percentage of isoniazid resistance (based on initial isolates from persons with no prior history of TB) was approximately two times higher than among U.S.-born persons. The percentage declined from 12.4 in 1993 to 9.6 in 2001 among foreign-born persons, while it decreased from 6.8 in 1993 to 4.5 in 2001 among U.S.-born persons.
