📈 Decoding the Micro-War: The HIV Within-Host Viral Dynamics Model 🦠

by

🧬 Overview and Conceptual Motivation While many epidemiological frameworks focus on transmission between individuals, the HIV Within-Host Viral Dynamics Model shifts attention to processes occurring inside a single infected individual. This model operates at the cellular scale and is central to understanding how Human Immunodeficiency Virus (HIV) interacts with the immune system, particularly CD4⁺ T … Read more

📈 Differential Infectivity: Decoding Stage-Structured Transmission in SEIR Models 🧬

by

🏗️ Conceptual Overview For many pathogens, infectiousness is not constant over the course of illness. Viral load, symptom severity, and contact behavior often vary markedly between early, peak, and late stages of infection. The Differential Infectivity (Stage-Structured) SEIR Model extends the classical SEIR framework by dividing the infectious period into multiple sequential stages, each with … Read more
