South Africa-Integration of environmental assessments into a Mass Active Case Finding program
In clinics and hospitals in Klerksdorp, South Africa, a Mass Active Case Finding (Mass ACF) initiative has been integrated into the Tuberculosis (TB) program in an effort to increase identification of undiagnosed TB and HIV. Household members of newly diagnosed TB cases seen in clinics and hospitals are consented and screened for active TB, latent TB, and HIV. Those with TB symptoms are asked to provide a sputum specimen for further testing. Household visits are conducted by four teams who, in total, visit approximately 40 households per week. There is current interest to include assessment of environmental exposures within the household with these Mass ACF visits. Data collected may be related to water quality, airborne allergens, secondhand smoke (SHS) exposure, particulates, or other potentially relevant household exposures or conditions. Household environmental data may be used to inform prevention efforts as well as to identify risk factors associated with TB transmission in the Klerksdorp area.
