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.

Dynamic mapping of dengue basic reproduction number [PDF]
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.

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.

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 ...

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 ...

Estimation of the Basic Reproduction Number for the COVID-19 Pandemic in Minnesota. [PDF]
IFAC Pap OnLine, 2021 This paper focuses on the dynamics of the COVID-19 pandemic and estimation of associated real-time variables characterizing disease spread. A nonlinear dynamic model is developed which enhances the traditional SEIR epidemic model to include additional variables of hospitalizations, ICU admissions, and deaths.

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 ...

Interpretation of the Basic and Effective Reproduction Number [PDF]
Journal of Preventive Medicine and Public Health, 2020 In epidemiology, the basic reproduction number (R0) is a term that describes the expected number of infections generated by 1 case in a susceptible population.
