Primary Isoniazid Resistance in U.S.-born vs.
United States, 1993–2004
| Slide 21. Primary Isoniazid Resistance
in U.S.-born vs. Foreign-born Persons, United States, 1993–2004.
This graph shows primary isoniazid resistance in U.S.-born
vs. 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 among foreign-born
persons than among U.S.-born persons. In foreign-born persons,
the percentage declined from 12.3% in 1993 to 10.4% in 2004,
including a drop below 10% in 2001. In U.S.-born persons,
the percentage decreased from 6.8% in 1993 to 4.0% in 2002,
and then increased to 4.4% in 2003 and 4.5% in 2004.
