StandardInfektmodell

The StandardInfektmodell, often translated as the Standard Infection Model, is a conceptual framework used in epidemiology to describe the dynamics of infectious disease transmission within a population. It is a foundational model upon which more complex epidemiological models are built. The model typically categorizes individuals into compartments based on their disease status. The most basic version, the SIR model, includes three compartments: Susceptible (S), Infected (I), and Recovered/Removed (R). Individuals in the susceptible compartment are able to contract the disease. Those in the infected compartment are currently infectious and can transmit the disease to susceptible individuals. Individuals in the recovered/removed compartment are no longer susceptible or infectious, either due to immunity or death.

The model uses differential equations to represent the rates of transition between these compartments. For instance, the rate at which susceptible individuals become infected is proportional to the number of susceptible individuals, the number of infected individuals, and a transmission rate parameter. Similarly, the rate at which infected individuals recover or are removed is typically proportional to the number of infected individuals and a recovery rate parameter. By solving these equations, epidemiologists can simulate the spread of an epidemic over time, predict the peak number of infections, and estimate the total number of people who will be affected. The StandardInfektmodell serves as a simplified representation, often neglecting factors like age structure, spatial distribution, or varying individual behaviors, but its core principles are essential for understanding disease spread. Variations of the model exist, such as the SEIR model, which includes an 'Exposed' (E) compartment for individuals who are infected but not yet infectious.
