Epidemiology of tuberculosis in the United States

After decades of decline, an unprecedented resurgence in tuberculosis occurred in the late 1980s and early 1990s. Deterioration of tuberculosis program infrastructure, the HIV/AIDS epidemic, drug-resistant tuberculosis, and tuberculosis among foreign-born persons contributed to the resurgence. Since then, tuberculosis case numbers have declined, but the decline in 2003 was the smallest since the resurgence. Key challenges remain, and efforts must focus on identifying and targeting interventions for high-risk populations, active involvement in the global effort against tuberculosis, developing new tools, and maintaining adequate resources.
