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 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 ...

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.

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.

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.

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.

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.

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.
