1997 Surveillance Slides

Primary Isoniazid Resistance Among TB Cases
United States, 1993 - 1997

Slide 18: Map Showing the Primary Isoniazid Resistance Among TB Cases United States, 1993 - 1997.
Slide 18. During 1993 through 1997, 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.
