Abstract:
Measuring tuberculosis (TB) prevalence trends provides information on progress towards the Millennium Development Goals. The World Health Organization recently published guidelines on assessing TB prevalence through population-based surveys. The current manuscript describes in detail the organisation of the field activities in such a survey. These activities need to be embedded in a strong organisational framework where the steering committee has the overall responsibility and the survey coordinator the day-to-day supervision. Field activities need to be tailored to the community, with respect to both time and place and direct involvement of community members. Frequent and well-described monitoring procedures need to be in place to be able to identify systematic and non-systematic errors at the earliest opportunity.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
