Assessing Tuberculosis Prevalence through Population - based surveys
Global Health Security Capacities
Description
Tuberculosis (TB) prevalence surveys are most valuable in areas where notification data obtained through routine surveillance are of unproven accuracy or incomplete, and in areas with an estimated prevalence of bacteriologically confirmed TB of more than 100 per 100 000. To help in assessing the performance of TB control programmes, to provide information for planning, and to assess trends of the disease burden over time, data on TB can be collected through standard methods in a well-defined study population. This document gives overall guidance in conducting crosssectional surveys of pulmonary TB disease. It is intended for TB experts and advisers at national and international levels, and investigators involved in prevalence surveys.
