BACKGROUND: Rates of latent tuberculosis infection (LTBI) and tuberculosis (TB) disease are elevated in the rural southeastern United States and among US- and foreign-born Black residents. To prevent TB and reduce TB transmission, community-based strategies are essential.
OBJECTIVE: To describe a community-based participatory intervention for improving the detection and treatment of LTBI and TB and reducing TB incidence.
DESIGN: In rural Florida, we carried out a community educational TB campaign from 1997 to 2000, including presentations at community events, a media campaign and working with local community groups to develop culturally appropriate prevention messages. The campaign was implemented concurrently with a population-based LTBI survey.
RESULTS: The annual TB incidence rate in the intervention area decreased from 81 per 100 000 in 1994-1997, to 42/ 100 000 in 1998-2001, and to 25/100 000 in 2002-2005 (P = 0.001). This decrease was not observed in communities where the intervention was not implemented. There was no decrease in the TB incidence rate ratio between Blacks and non-Blacks in either region during the study period.
CONCLUSIONS: We conclude that community participation in LTBI screening and TB education was associated with a substantial reduction in TB rates. Although the TB incidence rate ratio did not decrease between Blacks and non-Blacks, TB incidence fell in all racial groups.
