Primary Isoniazid Resistance Among TB Cases
United States, 1993 - 1998
|Slide 17: Primary Isoniazid Resistance
Among TB Cases, 1993-1998. During 1993 through 1998,
primary isoniazid resistance (estimated by analyzing data
from persons without a history of previous TB) was at least
4% in 46 states and the District of Columbia. When the level
of primary isoniazid resistance in the community is at least
4%, an initial regimen of four first-line drugs is recommended.
Individual patient factors (e.g., history of previous TB,
birth in a country with a high prevalence of drug resistance)
should also be considered when choosing the initial drug regimen
for TB patients.
