Basic reproduction number and effective reproduction number for North Cyprus for fighting Covid-19
Қарағанды университетінің хабаршысы. Математика сериясы, 2020 The aim of this paper is to show how North Cyprus fought with Covid-19 by using R0 and Rt, as herd immunity. For that purpose, we used a SEIR model for basic reproduction number, R0, and calculated Rt values by using R0 values. North Cyprus is the first

Mathematical modeling of the impact of treatment on the dynamics of typhoid
Journal of the Egyptian Mathematical Society, 2021 In this paper, we propose a mathematical model for the transmission of typhoid which analyzes the impact of treatment of the infected individuals on the dynamics of the disease. The model consists of human population and pathogen population.

Various Logistic Curves in SIS and SIR Models [PDF]
European Journal of Mathematics and Statistics, Vol.4(2023), 1-6, 2022 In our previous paper, the logistic curve of the removed number was derived from SIR and SEIR models in the case of the small basic reproduction number. In this paper, we derive various logistic curves of the removed, unsusceptible and infectious numbers respectively from SIS and SIR models in the case of small and large basic reproduction numbers.

A network immuno-epidemiological model of HIV and opioid epidemics
Mathematical Biosciences and Engineering, 2023 In this paper, we introduce a novel multi-scale network model of two epidemics: HIV infection and opioid addiction. The HIV infection dynamics is modeled on a complex network. We determine the basic reproduction number of HIV infection, $ \mathcal{R}_{v}

Estimation of the Reproductive Number Trend of the Novel Coronavirus ”COVID-19“ in Southern Iran from July to November 2020 [PDF]
Iranian Journal of Medical Sciences, 2022 Background: Effective measures to control COVID-19 should be based on an understanding of its epidemiological pattern and the evaluation of its prevalence in the community. This study aimed to examine the reproductive number (R) of COVID-19 and its trend

On the basic reproduction number in semi-Markov switching networks
Journal of Biological Dynamics, 2021 Basic reproduction number $ \mathcal {R}_0 $ in network epidemic dynamics is studied in the case of stochastic regime-switching networks. For generality, the dependence between successive networks is considered to follow a continuous time semi-Markov ...
