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.

On the basic reproduction number in a random environment
Journal of Mathematical Biology, 2012 The concept of basic reproduction number R0 in population dynamics is studied in the case of random environments. For simplicity the dependence between successive environments is supposed to follow a Markov chain. R0 is the spectral radius of a next-generation operator.

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 ...

Global convergence of COVID-19 basic reproduction number and estimation from early-time SIR dynamics
medRxiv, 2020 The SIR ('susceptible-infectious-recovered') formulation is used to uncover the generic spread mechanisms observed by COVID-19 dynamics globally, especially in the early phases of infectious spread.

A superinfection model on malaria transmission: analysis on the invasion basic reproduction number
, 2021 Malaria is one of the many kinds of vector-borne diseases which threaten many developing countries around the world every year. Malaria is caused by more than one type of Plasmodium, which allows a superinfection between two kinds of Plasmodium in the ...

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 ...

Estimation of the basic reproduction number of measles during an outbreak in a partially vaccinated population [PDF]
, 2000 From March to July 1996 a measles outbreak occurred in northern Luxembourg with 110 reported cases centered around two primary schools (85 cases) and the surrounding community (25 cases). Eighty four suspected cases were confirmed serologically.
