This paper introduces CAST, a polynomial-time approximation algorithm for strategically allocating HIV treatment resources to virally unsuppressed individuals in a transmission network to minimize new infections, outperforming existing baselines on real-world networks.
Early clinical trial results show that repurposing CAR-T cell therapy, originally used for cancer, can help control HIV long-term. Two patients achieved undetectable HIV levels after a single infusion and stopped medications, suggesting a potential functional cure.
