HIV Prevention via Cascade-Aware Suppression of Transmission Algorithm
An innovative algorithm known as Cascade-Aware Suppression of Transmission (CAST) seeks to enhance HIV prevention by effectively allocating intensive resources to individuals who are virally unsuppressed. This study frames the issue as a constrained optimization problem, where resources can be utilized to treat k individuals from a group P of unsuppressed cases, aiming to reduce the anticipated cascade of new infections within a transmission network. CAST operates as a polynomial-time (δ, ε)-approximation algorithm, providing a 2√|P| approximation ratio. The research tackles the limitations imposed by systemic resource constraints on intervention strategies, utilizing antiretroviral therapy's capacity to eliminate transmission risk upon achieving viral suppression. The findings are available on arXiv under ID 2605.20218.
