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.

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

The basic reproduction number of COVID-19 across Africa
medRxiv, 2021 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 ...

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.

The basic reproduction number, $R_0$, in structured populations [PDF]
Mathematical Biosciences, 2019 In this paper, we provide a straightforward approach to defining and deriving the key epidemiological quantity, the basic reproduction number, $R_0$, for Markovian epidemics in structured populations.

Dengue disease, basic reproduction number and control [PDF]
International Journal of Computer Mathematics, 2011 Dengue is one of the major international public health concerns. Although progress is underway, developing a vaccine against the disease is challenging. Thus, the main approach to fight the disease is vector control.

Efficient numerical computation of the basic reproduction number for structured populations. [PDF]
J Comput Appl Math, 2021 As widely known, the basic reproduction number plays a key role in weighing birth/infection and death/recovery processes in several models of population dynamics. In this general setting, its characterization as the spectral radius of next generation operators is rather elegant, but simultaneously poses serious obstacles to its practical determination.

On the basic reproduction number in semi-Markov switching networks [PDF]
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 ...

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