Large U.S. cities found to carry significant TB burden

There is a significant tuberculosis burden in large U.S. cities, according to a new report.

A new study recently published by the American Journal of Public Health investigated the annual characteristics and incidence rates of TB patients in 48 large U.S. cities. The study found that 42,448 patients with TB in 48 cities accounted for 36 percent of all U.S. patients with TB, comprising 15 percent of the total U.S. population, according to

Investigators compared demographic, clinical and treatment data characteristics of TB patients. The cities were examined from 2000 to 2007 and were categorized as reporting decreasing or non-decreasing rates in comparison with the rates reported by the U.S. Centers for Disease Control and Prevention’s National TB Surveillance System.

The research demonstrated that 29 of the 48 investigated cities showed no change in tuberculosis rates over the seven years they were examined, reports. This raises a concern over the feasibility of eliminating TB under current policies.

"Our study illustrates the need to address the continuing challenges of urban TB control and highlights some of the factors contributing to variability of TB trends among cities," the study reported, according to "It is important to detail how specific characteristics of the urban environment shape health and how observations may extend to different urban contexts."
