The transmission model based on the Incidence Patterns Model.

<p>The transmission model uses the posterior distribution from the IPM on the number of new infections acquired and the HIV prevalence in each population group to estimate the distribution of infections transmitted by each group using prior information on the mixing patterns between groups, transmissibility (depending on transmission probability, condom use, STI prevalence), and ART coverage in each group. The diagram is illustrative and does not specifically represent the groups described in the study. The intensity of the grey cells reflects the magnitude of the factors described.</p> <p>DHS, Demographic and Health Surveys; IPM, Incidence Patterns Model; STI, sexually transmitted infection.
