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.

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.

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 ...

Genealogy with seasonality, the basic reproduction number, and the influenza pandemic [PDF]
Journal of Mathematical Biology, 2010 The basic reproduction number R (0) has been used in population biology, especially in epidemiology, for several decades. But a suitable definition in the case of models with periodic coefficients was given only in recent years. The definition involves the spectral radius of an integral operator.

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

Convex Optimization of the Basic Reproduction Number
IEEE 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.

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.

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

The basic reproduction number for scrapie [PDF]
Proceedings of the Royal Society of London. Series B: Biological Sciences, 1999 The basic reproduction number R0 provides a quantitative assessment of the ability of an infectious agent to invade a susceptible host population. A mathematical expression for R0 is derived based on a recently developed model for the spread of scrapie through a flock of sheep.
