Estimation of the basic reproduction number of Alpha and Delta variants of COVID-19 pandemic in Iran. [PDF]

PLoS One, 2022
Estimating the basic reproduction number of a pandemic and the changes that appear on this value over time provide a good understanding of the contagious nature of the virus and efficiency of the controlling strategies.

The basic reproduction number of COVID-19 across Africa. [PDF]

PLoS ONE, 2022
The pandemic of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) took the world by surprise. Following the first outbreak of COVID-19 in December 2019, several models have been developed to study and understand its transmission dynamics ...

Social, economic, and environmental factors influencing the basic reproduction number of COVID-19 across countries. [PDF]

PLoS One, 2021
Objective: To assess whether the basic reproduction number (R0) of COVID-19 is different across countries and what national-level demographic, social, and environmental factors characterize initial vulnerability to the virus.

The Basic Reproduction Number as a Loop Gain Matrix. [PDF]

IEEE Control Syst Lett, 2022
The COVID-19 pandemic and the disordered reactions of most governments made the importance of mathematical modelling and model-based predictions evident, even outside the scientific community.

Estimation of the basic reproduction number (R0) for the novel coronavirus disease in Sri Lanka

Virology Journal, 2020
Background The basic reproduction number (R0) is the number of cases directly caused by an infected individual throughout his infectious period. R0 is used to determine the ability of a disease to spread within a given population. The reproduction number

Studies on the basic reproduction number in stochastic epidemic models with random perturbations. [PDF]

Adv Differ Equ, 2021
In this paper, we discuss the basic reproduction number of stochastic epidemic models with random perturbations. We define the basic reproduction number in epidemic models by using the integral of a function or survival function.

Estimating epidemic exponential growth rate and basic reproduction number

Infectious 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.

Basic reproduction number of SEIRS model on regular lattice

Mathematical Biosciences and Engineering, 2019
In this paper we give a basic reproduction number $\mathscr{R}_0$ of an SEIRS model on regular lattice using next-generation matrix approach. Our result is straightforward but differs from the basic reproduction numbers for various fundamental epidemic ...
