Расширяя классическую модель SIR (Восприимчивый-Инфекционный-Выздоровевший), включив в нее пространственную зависимость, мы исследуем, как волны заболеваний распространяются среди населения. Посредством математического анализа и вывода мы выводим уравнения для скорости распространения волн и оцениваем серьезность эпидемий. Наши результаты подчеркивают решающую роль снижения коэффициента контакта в замедлении распространения болезни и минимизации ее последствий. Исследование подчеркивает силу математического моделирования в понимании пандемий и борьбе с ними, предлагая понимание стратегий эффективного вмешательства.</p></abstract><trans-abstract xml:lang="en"><p>This paper examines pandemic dynamics using running-wave-based tools and mathematical models. By extending the classic SIR (Susceptible-Infected-Removed) model to include spatial dependence, we explore how disease waves spread across a population. Through mathematical analysis and inference, we derive equations for the wave velocity and assess the severity of epidemics. Our findings emphasise the crucial role of reducing the contact factor in slowing the spread of a disease and minimising its consequences. The study highlights the power of mathematical modelling in understanding and responding to pandemics, suggesting insights into effective intervention strategies.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>динамика пандемии</kwd><kwd>бегущие волны</kwd><kwd>математическое моделирование</kwd><kwd>модель SIR</kwd><kwd>пространственная зависимость</kwd><kwd>скорость волны</kwd><kwd>тяжесть эпидемии</kwd><kwd>коэффициент контактности</kwd><kwd>распространение болезни</kwd><kwd>стратегии вмешательства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pandemic dynamics</kwd><kwd>running waves</kwd><kwd>mathematical modelling</kwd><kwd>SIR model</kwd><kwd>spatial dependence</kwd><kwd>wave velocity</kwd><kwd>epidemic severity</kwd><kwd>contact rate</kwd><kwd>disease spread</kwd><kwd>intervention strategies</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Emerging Pandemics: Connections with Environment and Climate Change (1st ed.) / S.
