A new study published online in the journal AIDS uses mathematical models to predict the potential impact of treating discordant couples with antiretroviral therapy, according to a Columbia University Mailman School of Public Health press release. Researchers from ICAP at the Mailman School and UCLA's Center for Biomedical Modeling made predictions for Ghana, Lesotho, Malawi and Rwanda (10/18). According to the study, the "effectiveness of a discordant couples intervention in reducing incidence will vary among countries due to differences in" population size, HIV prevalence and the percentage of couples who are discordant (El-Sadr et al., 10/11).
