A formal framework to convey ideas about the components of a host-parasite interaction. Construction requires three major types of information: (a) a clear understanding of the interaction within the individual host between the infectious agent and the host, (b) the mode and rate of transmission between individuals, and (c) host population characteristics such as demography and behaviour. Mathematical models can aid exploration of the behaviour of the system under various conditions from which to determine the dominant factors generating observed patterns and phenomena. They also aid data collection and interpretation and parameter estimation, and provide tools for identifying possible approaches to control and for assessing the potential impact of different intervention measures.
Related Topics: [ model] A set of mathematical equations which attempts to predict the behavior of a physical system(s). For example, the Rational Formula, Q = Cia, is a mathematical model for peak runoff rate prediction with a single dependent variable, Q, and three independent parameter s: C, i and A. Often the term "simulation model" is used in lieu of mathematical model, because the relationships are intended to simulate actions of physical systems.
