Dictionary meaning
the quantitative description and mathematical modelling of the processes by which infectious diseases spread through populations, encompassing the routes, rates, and drivers of pathogen transfer from infectious to susceptible individuals; transmission dynamics are characterised by parameters including the basic reproduction number, the serial interval, the incubation period, the infectious period, and the force of infection, which together determine the trajectory of an epidemic and the effectiveness of control interventions; understanding transmission dynamics allows epidemiologists to evaluate the expected impact of non-pharmaceutical interventions such as social distancing, mask wearing, and contact tracing, as well as vaccination campaigns, on epidemic growth and ultimate size
