UNAIDS has set treatment targets, to be achieved by 2030, that are necessary to ensure the successful elimination of HIV worldwide: specifically, to diagnose 95% of people with HIV (PHIV), to treat 95% of the diagnosed, and to attain viral suppression in 95% of the treated [1]. In an interesting study in this issue of AIDS, Shen et al.[2] model the transmission dynamics of the HIV epidemic in China where the achieved treatment targets are only 71%, 80%, and 65%. As the authors note, a high rate of attrition is a major barrier to achieving success. The authors predict the impact of attrition–when expanding treatment–on transmission, the risk of developing drug-resistant strains (ie acquired resistance), the transmission of drug-resistant strains (ie transmitted resistance), and HIV-related mortality.Shen et al.[2] parameterized their model using annual HIV/AIDS surveillance data that were collected between 2008 and 2018 by the Guangxi Center for Disease Control and Prevention. They modeled a single treatment regimen based on nucleoside reverse transcriptase inhibitors (nRTIs), non-NRTIs (nnRTI), and protease inhibitors; the one strain of drug-resistance that developed, and was subsequently transmitted, was assumed to be resistant to all three classes. They predicted the impact of simultaneously increasing both the attrition rate and the treatment rate over an 8-year period: 2022–2030. Their results showed that some combinations of rates decreased transmitted resistance, the cumulative number of new infections, and HIV-related deaths; however, other combinations increased these quantities. Notably, they showed that–in some cases–a small increase in attrition could offset the benefits of treatment expansion. Consequently, they concluded that ‘reducing
