Outline of Final Research Achievements

A statistical model describing sexual partnering was established for estimation of sexual behavior at population level. The analysis of association between HIV prevalence and model parameters in the model described above showed no clear association, this suggests that the estimation of HIV prevalence from sexual behavior survey is difficult. Towards to evaluate efficacy of an alternative method, the estimation of HIV prevalence from the HSV-2 prevalence, the association of HIV and HSV-2 prevalences was explored. The result suggests the association depends on topology of sexual contact network.
