Calculation of the effective reproduction number

International Journal of Modern Physics C
The basic reproduction number R 0 is a key epidemiological quantity, representing the expected number of new cases obtained from receiving a pathogen from one infected individual in totally susceptible population.

Improving the estimation of the COVID-19 effective reproduction number using nowcasting [PDF]

Statistical Methods in Medical Research, 2021
As the interactions between people increases, the impending menace of COVID-19 outbreaks materializes, and there is an inclination to apply lockdowns. In this context, it is essential to have easy-to-use indicators for people to employ as a reference. The effective reproduction number of confirmed positives, Rt, fulfills such a role.

Effective reproduction numbers are commonly overestimated early in a disease outbreak

Statistics in Medicine, 2011
AbstractReproduction numbers estimated from disease incidence data can give public health authorities valuable information about the progression and likely size of a disease outbreak. Here, we show that methods for estimating effective reproduction numbers commonly give overestimates early in an outbreak.

Longitudinal evolution of the HIV effective reproduction number following sequential expansion of treatment as prevention and pre-exposure prophylaxis in British Columbia, Canada: a population-level programme evaluation.

The Lancet HIV
BACKGROUND Treatment as prevention and pre-exposure prophylaxis (PrEP) are key strategies in the control of HIV/AIDS. We aimed to characterise the longitudinal effects of antiretroviral therapy (ART), followed by treatment as prevention and the addition ...

Characterizing Outbreak Trajectories and the Effective Reproduction Number

2019
Emerging and re-emerging infectious diseases pose major challenges to public health worldwide. Fortunately mathematical and statistical inference and simulation approaches are part of the toolkit for guiding prevention and response plans. As the recent 2013–2016 Ebola epidemic exemplified, an unfolding infectious disease outbreak often forces public ...
