Estimating the Basic Reproductive Number from Viral Sequence Data [PDF]
Molecular Biology and Evolution, 2011 Epidemiological processes leave a fingerprint in the pattern of genetic structure of virus populations. Here, we provide a new method to infer epidemiological parameters directly from viral sequence data. The method is based on phylogenetic analysis using a birth-death model (BDM) rather than the commonly used coalescent as the model for the ...

Global dynamics of a periodic SEIRS model with general incidence rate [PDF]
, 2017 We consider a family of periodic SEIRS epidemic models with a fairly general incidence rate and it is shown the basic reproduction number determines the global dynamics of the models and it is a threshold parameter for persistence.

Lyapunov Functions for Tuberculosis Models with Fast and Slow Progression [PDF]
, 2006 The spread of tuberculosis is studied through two models which include fast and slow progression to the infected class. For each model, Lyapunov functions are used to show that when the basic reproduction number is less than or equal to one, the disease ...

Estimation of the Reproductive Number Trend of the Novel Coronavirus ”COVID-19“ in Southern Iran from July to November 2020 [PDF]
Iranian Journal of Medical Sciences, 2022 Background: Effective measures to control COVID-19 should be based on an understanding of its epidemiological pattern and the evaluation of its prevalence in the community. This study aimed to examine the reproductive number (R) of COVID-19 and its trend

The epidemiology of canine leishmaniasis: transmission rates estimated from a cohort study in Amazonian Brazil [PDF]
, 1997 We estimate the incidence rate, serological conversion rate and basic case reproduction number (R0) of Leishmania infantum from a cohort study of 126 domestic dogs exposed to natural infection rates over 2 years on Marajó Island, Pará State, Brazil.

Estimating the reproduction number of Ebola virus (EBOV) during the 2014 outbreak in West Africa [PDF]
, 2014 The 2014 Ebola virus (EBOV) outbreak in West Africa is the largest outbreak of the genus Ebolavirus to date. To better understand the spread of infection in the affected countries, it is crucial to know the number of secondary cases generated by an ...

Asymptomatic transmission shifts epidemic dynamics
Mathematical Biosciences and Engineering, 2021 Asymptomatic transmission of infectious diseases has been recognized recently in several epidemics or pandemics. There is a great need to incorporate asymptomatic transmissions into traditional modeling of infectious diseases and to study how ...

A review of epidemiological parameters from Ebola outbreaks to inform early public health decision-making. [PDF]
, 2015 The unprecedented scale of the Ebola outbreak in West Africa has, as of 29 April 2015, resulted in more than 10,884 deaths among 26,277 cases. Prior to the ongoing outbreak, Ebola virus disease (EVD) caused relatively small outbreaks (maximum outbreak ...
