SUMMARY:Training workshop in population size estimation\, 15-18 June 2026
DESCRIPTION:Description \nEstablishing the size of various populations at risk for HIV has been identified as one of the greatest challenges in HIV surveillance and in developing estimates of HIV prevalence and incidence. Reliable estimates of the size of populations at high risk of HIV are important for prioritizing target populations\, planning HIV prevention services\, measuring coverage with these services and monitoring and evaluation of interventions. Credible estimates of population size contribute to documenting progress in HIV prevention scale-up and in obtaining continued funding for the provision of various services. \nThe aim of the course is to provide participants with practical guidance on how to design studies to estimate the size of populations at higher risk for HIV (female sex workers [FSW]\, people who inject drugs [PWID]\, men who have sex with men [MSM])\, conduct these studies\, and\, interpret and use the data. The course will provide examples of lessons learned around the world in implementation of size estimates studies and challenges in interpretation of various data sources. \nKey topics of the course are:  \n\nMethods of population size estimates: geographical mapping; virtual mapping\, multiplier method; three-source capture-recapture; network scale-up\nInterpreting diverging results of the size estimates studies\nExtrapolation of data at sub-national and national level\nCalculating indicators of programme coverage based on the size estimation data\nDesigning size estimates studies and writing-up results\n\n  \nObjectives of the course are the following: \n\nTo learn about various methods and field procedures for size estimation studies\nTo learn how to use multiple data sources to develop size estimates and how to extrapolate local-level results to sub-national and national level\nTo build skills in developing protocols for estimation studies\nTo acquire skills in the analysis of size estimation data\n\nParticipants will be given an opportunity to share their own country-specific experiences and challenges in estimating the size of high-risk groups.  \nTeaching Methods \nThe course consists of lectures\, presentation of case studies\, active class discussion\, exercises and group work. The course is designed to provide participants with practical skills and knowledge on how to conduct size estimation studies. \n  \nTarget Audience \nEpidemiologists\, demographers\, public health professionals\, social scientists \n  \nLecturers \nProfessor George W.
