Building a tool model for the study of the ecosystem “Coronavirus – vector – human - environment”

Abstract

Massive contagious diseases (epidemics, pandemics) that quickly spread over large areas and can migrate from one country to another have been studied by such scientists as E. Johnner (1796), P. Louis (1879), I. Mechnikov (1883) and others. I. Mechnikov the immunity to infectious diseases associated with innate and acquired immunity. In turn, both innate and acquired immunity can be natural, if immunity is acquired as a result of a disease, or artificially acquired as a result of preventive vaccinations or the administration of artificial sera. In early 2020, the World Health Organization announced a pandemic of a new coronavirus infection due to its rapid spread in 170 countries. A person can be infected with coronavirus through different biological media, but first of all it is a respiratory disease. Coronavirus CoVID19 is a further mutation of the virus strain–SARS-pneumonia, also known as SARS-CoV-2. COVID19 contains 16 unstructured and structured proteins and has a large genome. Two models of solving the problem with COVID19, adopted in different countries, are considered: the first is complete self-isolation; the second is partial isolation of people with compromised immune systems. A graphic chart of the state and transition model of the Virus Source, Viral Vector, Recipient and Environment (CoV-E-V-P) system was constructed and analyzed. The change in human health state under the influence of the element parameters of the system is researched. The functional structure of the information model for monitoring and decision management system CoV-E-V-P is designed.
