  • Title: A rapid assessment of prevailing policies on tuberculosis contact investigation.
    Author: Hwang TJ, Ottmani S, Uplekar M.
    Journal: Int J Tuberc Lung Dis; 2011 Dec; 15(12):1620-3. PubMed ID: 22118168.
    Abstract:
    Contact investigation contributes to improving early case detection of tuberculosis (TB). However, its implementation in low-income, high TB burden countries remains limited. A multicountry survey of contact investigation policies was conducted to evaluate the extent of their implementation. Our results showed significant heterogeneity in definitions and procedures, with over 25% of countries unable to provide a clear definition of a contact. Estimates indicate that routine implementation of contact investigation policies globally could help detection of over a quarter of a million cases. International guidelines should be developed to support national TB programmes to initiate and scale up systematic TB contact investigation.
