Complexity of the Basic Reproduction Number (R0) [PDF]
Emerging Infectious Diseases, 2019 The basic reproduction number (R0), also called the basic reproduction ratio or rate or the basic reproductive rate, is an epidemiologic metric used to describe the contagiousness or transmissibility of infectious agents.

Estimating the basic reproduction number at the beginning of an outbreak. [PDF]
PLoS ONE, 2022 We compare several popular methods of estimating the basic reproduction number, R0, focusing on the early stages of an epidemic, and assuming weekly reports of new infecteds.

Preliminary prediction of the basic reproduction number of the Wuhan novel coronavirus 2019-nCoV [PDF]
Journal of Evidence Based Medicine (2020) 1, 2020 Objectives.--To estimate the basic reproduction number of the Wuhan novel coronavirus (2019-nCoV). Methods.--Based on the susceptible-exposed-infected-removed (SEIR) compartment model and the assumption that the infectious cases with symptoms occurred before January 25, 2020 are resulted from free propagation without intervention, we estimate the basic

Dynamic mapping of dengue basic reproduction number
Results in Physics, 2021 We developed a method to produce time-varying maps for dengue transmission risk, using the Ross-Macdonald framework and differential equations to estimate spatially the basic reproduction number (R0) of a vector-borne disease.

On the basic reproduction number in continuously structured populations [PDF]
Mathematical methods in the applied sciences, 2020 In the framework of population dynamics, the basic reproduction number R_0 is, by definition, the expected number of offspring that an individual has during its lifetime. In constant and time periodic environments it is calculated as the spectral radius of the so-called next-generation operator.

Deterministic epidemic models overestimate the basic reproduction number of observed outbreaks [PDF]
Infectious Disease ModellingThe 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.

Basic Reproduction Number of Chikungunya Virus Transmitted by Aedes Mosquitoes [PDF]
Emerging Infectious Diseases, 2020 We estimated the weighted mean basic reproduction number (R0) of chikungunya virus based on outbreak size. R0 was 3.4 (95% CI 2.4–4.2) and varied for 2 primary chikungunya mosquito vectors: 4.1 (95% CI 1.5–6.6) for Aedes aegypti and 2.8 (95% CI 1.8–3.8 ...

The study of human monkeypox disease in 2022 using the epidemic models: herd immunity and the basic reproduction number case. [PDF]
Ann Med Surg (Lond), 2023 As of May 2022, a new outbreak of the human monkeypox (MPOX) disease appeared in multiple countries, where the 2022 human MPOX disease spread to more than 109 cases, excluding the suspected cases up to the end of 2022.
