Basic reproduction number and effective reproduction number for North Cyprus for fighting Covid-19

open access: yesҚарағанды 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

Estimating epidemic exponential growth rate and basic reproduction number

open access: yesInfectious Disease Modelling, 2020
The initial exponential growth rate of an epidemic is an important measure of the severeness of the epidemic, and is also closely related to the basic reproduction number.

Deterministic epidemic models overestimate the basic reproduction number of observed outbreaks [PDF]

open access: yesInfectious Disease Modelling
The basic reproduction number, R0, is a well-known quantifier of epidemic spread. However, a class of existing methods for estimating R0 from incidence data early in the epidemic can lead to an over-estimation of this quantity.

An Introduction to The Basic Reproduction Number in Mathematical Epidemiology★ [PDF]

open access: yesESAIM: Proceedings and Surveys, 2018
This article introduces the notion of basic reproduction number R0 in mathematical epi-demiology. After an historic reminder describing the steps leading to the statement of its mathematical definition, we explain the next-generation matrix method ...

Amplification of the basic reproduction number in cattle farm networks. [PDF]

open access: yesPLoS ONE, 2018
The popularly known 20-80 rule or Pareto rule states that 20% of efforts leads to 80% of results. This rule has been applied to the study of infection transmission in contact networks, and specifically, contact networks between cattle farms.

Effects of Demographic and Weather Parameters on COVID-19 Basic Reproduction Number

open access: yesFrontiers in Ecology and Evolution, 2021
It is hard to overstate the importance of a timely prediction of the COVID-19 pandemic progression. Yet, this is not possible without a comprehensive understanding of environmental factors that may affect the infection transmissibility.

The Dynamic Effective Reproductive Number of COVID-19 during the Epidemic in Iran

open access: yesIranian Journal of Public Health, 2022
Background: We aimed to determine the generation time, the best model for estimating reproduction number (R), and to estimate the basic reproduction number (R0) and effective reproduction number (Rt) for COVID-19 in Iran.

Convex Optimization of the Basic Reproduction Number

open access: yesIEEE Transactions on Automatic Control, 2022
The basic reproduction number $R_0$ is a fundamental quantity in epidemiological modeling, reflecting the typical number of secondary infections that arise from a single infected individual. While $R_0$ is widely known to scientists, policymakers, and the general public, it has received comparatively little attention in the controls community.
