New research indicates that identifying specific neighborhoods with a high TB incidence and then testing and treating all residents for the disease eliminated TB cases in those communities. Latent tuberculosis infection (LTBI) accounted for the development of most TB cases. By identifying geographic areas with persistent high incidence of both LTBI and active TB disease, researchers could locate two specific neighborhoods in Smith County, Texas, with a high TB risk. The study revealed a positive result from geographically targeting specific high-risk clusters and predicted that researchers prevented an estimated seven to 14 TB cases as a result of the targeted screening and treatment. The study, “Eliminating Tuberculosis One Neighborhood at a Time,” was published online in the American Journal of Public Health (AJPH) (2012; doi: 10.2105/AJPH.2012.300781), and will be published in print in the AJPH July 2013 issue (
