Title: Achieving TB Control In Zambia Through Scale Up Of Innovative Tools And Proven Active TB Case Finding Interventions
Brief Summary: To achieve TB control, innovative case finding interventions are needed that will reach the broader affected population including those that do not access the health facilities. Systematic community case finding with highly sensitive screening and diagnostic tools are needed. At the facility level, the index of suspicion for TB by health care workers needs to be raised to ensure that all those that need TB screening are appropriately screened.
