| Slide 22. Primary MDR TB in U.S.-born vs.
Foreign-born Persons, United States, 1993–2007. This graph
highlights primary MDR TB in U.S.-born versus foreign-born persons.
The percentage with primary MDR TB has declined among both groups,
although the decline in the U.S.-born has been greater. As a result,
the pro-portion of primary MDR TB cases reported in foreign-born
persons increased from approximately 25% of all MDR TB cases in 1993
to approximately 70% of all MDR TB cases in 1999, and continued to
increase to ap-proximately 80% in 2007 (not shown on slide). Among
the U.S.-born, the percentage with MDR TB remained between 0.5% and
0.7% from 1998 through 2004 and dropped to 0.5% in 2007. The
percentage among for-eign-born persons has fluctuated year by year,
while averaging approximately 1.4% from 1998 through 2007. Back to
