Corporate author: 
Publication details: 
Geneva, WHO, 2010

Use this guideline to conduct population size estimate studies to measure and understand the populations most at risk to HIV in your country. Note that the guideline does not cover issues around behavioural and biological surveillance among these populations. Refer to the Guidelines on Surveillance on Most at Risk Populations and Second Generation Surveillance in this same series for additional information.

A Participant’s Manual and slide presentations for training have been developed in conjunction to these Guidelines and can be found on the UNAIDS website. Alternative materials for conducting training on size estimates in Asia are also available from Partnership for Epidemic Analysis.
