Slide 2. Reported TB Cases, United States, 1982–2012. The resurgence of TB in the mid-1980s was marked by several years of increasing case counts until its peak in 1992. Case counts began decreasing again in 1993, and 2012 marked the twentieth year of decline in the total number of TB cases reported in the United States since the peak of the resurgence. From 1992 until 2002, the total number of TB cases decreased 5%–7% annually. From 2002 to 2003, however, the total number of TB cases decreased by only 1.4%. An unprecedented decrease occurred in 2009, when the total number of TB cases decreased by more than 10% from 2008 to 2009. In 2012, a total of 9,945 cases were reported from the 50 states and the District of Columbia (DC). This represents a decline of 5.9% from 2012 and 69.2% from 1992.
