Non-selective distribution of infectious disease prevention may outperform risk-based targeting

B. Steinger, I. Iacopini, et al.

This groundbreaking research by Benjamin Steinger, Iacopo Iacopini, Andreia Sofia Teixeira, Alberto Bracchi, Pau Casanova-Ferrer, Alberto Antonioni, and Eugenio Valdano reveals that non-selective distribution methods for infectious disease prevention may be more effective than targeting high-risk groups, particularly when prevention efficacy falls below a critical level. Explore how this could transform HIV prevention strategies in communities.

Abstract
This paper challenges the conventional wisdom of prioritizing high-risk individuals for infectious disease prevention by demonstrating that non-selective distribution can be more effective, particularly when the efficacy of prevention is below a critical threshold. Using pre-exposure prophylaxis (PrEP) for HIV among men who have sex with men (MSM) as a case study, the authors show that in many communities, a non-selective approach surpasses risk-based strategies. This finding has significant implications for designing more feasible and successful prevention programs.
