Slide 2: Reported TB Cases, United States, 1978-1998. The resurgence of TB in the mid 1980s was marked by several years of slowly increasing case counts followed by a substantial rise for several years. The total number of TB cases peaked in 1992. Since 1992, the total number of TB cases has decreased 5%-7% annually. This decline in reported TB cases has been attributed to stronger TB control programs that emphasize promptly identifying persons with TB, initiating appropriate therapy, and ensuring completion of therapy. Large declines in areas with high AIDS rates support findings that improved measures to prevent or control recent transmission have been the primary determinants of declining TB incidence. Reduction of nosocomial transmission through improved infection control programs, combined with more potent therapies for patients with multidrug-resistant TB, also appears to have helped reduce TB cases in some areas.
