Slide 20. Primary MDR TB, United States, 1993–2008. This graph focuses on trends in primary MDR TB (based on initial isolates from persons with no prior history of TB) in the United States from 1993 through 2008. The number of primary MDR TB cases, represented by bars, steadily declined from 407 in 1993 to 115 in 2001. Since then the total number of primary MDR TB cases has fluctuated from 86 to 132 cases, with 86 cases reported for 2008. Primary MDR TB, shown by the line, decreased from 2.5% in 1993 to approximately 1.1% in 1997, and remained approximately at 1.1% up to and including 2008. Back to 2008 Surveillance Slides Main Page
