household contact investigation

We present Ethiopia's experience in implementing LTBI management. Our objective is to share promising practices and existing opportunities and to suggest specific steps required for further scale up of the services. Our report is based on synthesis of data from secondary sources including official routine reports of Ministry of Health, materials presented at review meetings, and findings from supervisory visits to districts and health facilities. Our results suggest that Ethiopia has made significant strides toward strengthening LTBI management in people living with HIV and among under-five-year-old household contacts of TB patients. The use of contact investigation as entry point for LTBI management could be taken as best practice.

To determine the yield of a household contact investigation for tuberculosis (TB) under routine programme conditions. The objective of this study was to determine the yield of a household contact investigation for tuberculosis (TB) under routine programme conditions.Between April 2013 and March 2014, TB clinic officers in Amhara and Oromia regions, Ethiopia, conducted symptom-based screening for household contacts of 6,015 smear-positive TB (SS+ TB) index cases. We calculated the yield in terms of number needed to screen (NNS) and number needed to test (NNT). The NNS to detect a TB case all forms and SS+ TB was respectively 40 and 132. The NNT to diagnose a TB case all forms and SS+ TB was respectively 2.4 and 8. The yield of the household contact investigation was over 10 times higher than the estimated prevalence in the general population; household contact investigations can serve as an entry point for childhood TB care.
