🧬 Antigenic Drift Diffusion: Modeling the Evolution of Viral Escape
📈 Conceptual Overview For rapidly evolving viruses such as Influenza and SARS-CoV-2, classical compartmental models assuming a static pathogen are insufficient. The Antigenic Drift Diffusion model extends epidemic modeling by treating viral antigenic properties as a continuous trait, allowing explicit representation of immune escape through gradual mutation. In this framework, viral strains move through an … Read more
