Basic reproduction number and effective reproduction number for North Cyprus for fighting Covid-19
Қарағанды университетінің хабаршысы. Математика сериясы, 2020 The aim of this paper is to show how North Cyprus fought with Covid-19 by using R0 and Rt, as herd immunity. For that purpose, we used a SEIR model for basic reproduction number, R0, and calculated Rt values by using R0 values. North Cyprus is the first

Nonlinear Observer to Estimate the Effective Reproduction Number of Infectious Diseases [PDF]
Communication in Biomathematical Sciences, 2021 In this paper, we design a Nonlinear Observer (NLO) to estimate the effective reproduction number (Rt) of infectious diseases. The NLO is designed from a discrete-time augmented Susceptible-Infectious-Removed (SIR) model. The observer gain is obtained by

Direct modelling from GPS data reveals daily-activity-dependency of effective reproduction number in COVID-19 pandemic [PDF]
Scientific Reports, 2022 During the COVID-19 pandemic, governments faced difficulties in implementing mobility restriction measures, as no clear quantitative relationship between human mobility and infection spread in large cities is known.

Improved estimation of the effective reproduction number with heterogeneous transmission rates and reporting delays [PDF]
Scientific ReportsIn the face of an infectious disease, a key epidemiological measure is the basic reproduction number, which quantifies the average secondary infections caused by a single case in a susceptible population.

Epidemics, 2018 The effective reproduction number, Rt, is a measure of transmission that can be calculated from standard incidence data to timely detect the beginning of epidemics. It has being increasingly used for surveillance of directly transmitted diseases. However,

Estimates of mpox effective reproduction number in Spain, April-August 2022. [PDF]
Epidemiol Infect, 2023 Abstract We analysed the transmission of the human mpox virus in Spain by estimating the effective reproduction number of the disease from official surveillance data. Our computations show that this decreased steadily after an initial burst phase, dropping below 1 on July 12, and thus the outbreak was expected to reduce in the following weeks ...

Estimating the measles effective reproduction number in Australia from routine notification data
Bulletin of the World Health Organization, 2014 Objective To estimate the measles effective reproduction number (R) in Australia by modelling routinely collected notification data. Methods R was estimated for 2009–2011 by means of three methods, using data from Australia's National Notifiable ...

Assessing the Time Evolution of COVID-19 Effective Reproduction Number in Brazil
Anais da Academia Brasileira de CiênciasIn this paper, we use a Bayesian method to estimate the effective reproduction number ( R ( t )), in the context of monitoring the time evolution of the COVID-19 pandemic in Brazil at different geographic levels.
