Opis:
We describe the information system that has been built for the support sanitary teams. The system is aimed at supporting analytical work which must be carried out when there is a risk of epidemic outbreak. It is meant to provide tools for predicting the size of an epidemic on the basis of the actual data collected during its course. Since sanitary teams try to control the size of the epidemics such a tool must model also sanitary teams activities. As a result a model for the prediction can be quite complicated in terms of the number of equations it contains. Furthermore, since a model is based on several parameters there must be a tool for finding these parameters on the basis on the actual data corresponding to the epidemic evolution. The paper describes the proposition of such a system. It presents, in some details, the main components of the system. In particular, the environment for building complex models (containing not only the epidemic model but also activities of sanitary teams trying to inhibit the epidemic) is discussed. Then, the module for a model calibration is presented. The module is a part of server for solving optimal control problems and can be accessed via Internet. Finally, we show how optimal control problems can be constructed with the aim of the efficient epidemic management. Some optimal control problems related to that issue are discussed and numerical results of its solution are presented.

Opis:
Niniejszy artykuł przedstawia numeryczne rozwiązania wybranych modeli rozprzestrzeniania się epidemii w języku programowania Python. Rozwiązania oparto na modelach epidemii SIS, SIR, SIRS oraz SEIR. Do rozwiązań numerycznych w języku Python wykorzystano biblioteki NumPy, SciPy oraz Matplotlib.
This article presents numerical solutions of selected epidemic spread models in the Python programming language. The solutions were base on the SIS, SIR, SIRS and SEIR epidemic models. NumPy, SciPy and Matplotlib libraries were used for numerical solutions in Python.

Opis:
Throughout the course of civilization, epidemics and pandemics have ravaged humanity, destroyed animal breeding and horticulture, and has also changed the course of history. It has been estimated that Justinian plague has affected half of the population of Europe and killed in three pandemics 50 million people, the avian-borne flu (Spanish flu), resulted in 50 million deaths worldwide in the years 1918–1919, and recently the COVID-19 is officially a pandemic, after barreling through 114 countries in just three months. In the past, rinderpest has hit Europe with three long panzootics, African swine fever (ASF), is still a threat to both the swine production industry and the health of wild boar populations. Several molecular changes occur in the pathogen that may trigger an epidemic or even pandemic. These include increase of virulence, introduction into a novel host, and changes in host susceptibility to the pathogen. Once the infectious disease threat reaches an epidemic or pandemic level, the goal of the response is to mitigate its impact and reduce its incidence, morbidity and mortality as well as disruptions to economic, political, and social systems. An epidemic curve shows progression of illnesses in an outbreak over time and the SIR, SI, SIRD and SEIR represent the simplest compartmental models that enable simplify the mathematical modelling of epidemics. This article throws a light on changing ideas in epidemiology of infectious diseases.
