Short term estimates of adult HIV incidence by mode of transmission: Kenya and Thailand as examples.

ABSTRACT:

Objective

Patterns of transmission of HIV are different among different regions of the world and change over time within regions. In order to adapt prevention strategies to changing patterns of risk, we need to understand the behaviours that put people at risk of infection and how new infections are distributed among risk groups.

Methods

A model is described to calculate the expected incidence of HIV infections in the adult population by mode of exposure using the current distribution of prevalent infections and the patterns of risk within different populations. For illustration the model is applied to Thailand and Kenya.

Results

New infections in Kenya were mainly transmitted through heterosexual contact (90%), while a small but significant number were related to inj
