The use of computer models of the spread of animal diseases in veterinary medicine based on an individual approach

Abstract

Computer models in veterinary medicine are used in veterinary medicine to simulate the spread of infectious and noncommunicable diseases, predict the consequences of the disease, plan, evaluate epizootic surveillance, control strategies, and obtain information about cause-and-effect relationships by comparing the results of the model with real-life data. There are various types of disease spread models, and this review article presents and describes the implementation of a certain type of disease - models based on an individual approach. The purpose of the review work is to develop models for the spread of infectious and non-communicable animal diseases based on an individual approach, their use and problems.The materials of the review article are based on the results of numerous epizootological, diagnostic studies, methods of mathematical statistics by scientists from Denmark, Ireland, Switzerland, Australia, Great Britain, Germany, Sardinia. Examples of programming languages and code are provided in order to make modeling methods more accessible to users. Important steps in building such models before, during, and after the programming phase are described, including: model verification to ensure that the model does what it was intended to do; model validation to determine whether the model results reflect the system being modeled; model convergence analysis to ensure its compliance with endemic diseases. A brief analysis of the sensitivity of the model is given, which is used to identify parameters and processes that have a significant impact on the predictions of the model. A brief overview of some interesting recent developments in the field of disease propagation models is provided.
