Abstract

OBJECTIVE: To validate the currently used empirical relationship between annual risk of tuberculous infection (ARTI) and incidence and prevalence of smear-positive cases. SETTING: Two disease surveys to estimate the prevalence and incidence of tuberculosis (TB) among adults in Tiruvallur district, south India, and a tuberculin survey to estimate the ARTI among children. RESULTS: The incidence of TB was estimated to be 82 and prevalence 210 per 100 000 population and ARTI 1.6%. We estimated that 1% ARTI corresponded to 51 new and 131 prevalent cases. CONCLUSION: The currently used empirical relationship between ARTI and incidence can be used by programme managers as an effective monitoring tool.
