🩸 The Catalytic Model: Decoding the Force of Infection from Serology 📈
🏗️ Conceptual Overview In mathematical epidemiology, direct observation of transmission intensity over long time horizons is often impossible. The Catalytic Model provides a principled method to infer the force of infection (λ)—the per capita rate at which susceptible individuals acquire infection—using cross-sectional serological data stratified by age. Rather than tracking infections forward in calendar time, … Read more
