Epidemiology

Rate at which susceptibles become infected

The force of infection is the per-capita rate at which susceptible individuals acquire an infection over time, the instantaneous hazard that a still-uninfected person becomes infected. It links the amount of circulating infection to how fast new cases accrue, and it typically varies with age and with how much disease is present in the population. Muench's 1934 Derivation of rates from summation data by the catalytic curve introduced the catalytic model that let this rate be inferred from age-prevalence data. The referent is a rate parameter governing the flow from susceptible to infected, central to transmission models.[1][2]

Probability of infection per susceptible per unit time
