Open AccessAssessment of fever screening at airports in detecting domestic passengers infected with SARS-CoV-2, 2020–2022, Okinawa prefecture, Japan
While airport screening measures for COVID-19 infected passengers at international airports worldwide have been greatly relaxed, observational studies evaluating fever screening alone at airports remain scarce...

Open AccessComparative epidemiology of five waves of COVID-19 in Mexico, March 2020–August 2022
The Mexican Institute of Social Security (IMSS) is the largest health care provider in Mexico, covering about 48% of the Mexican population. In this report, we describe the epidemiological patterns related to ...

Open AccessCharacterizing all-cause excess mortality patterns during COVID-19 pandemic in Mexico
Low testing rates and delays in reporting hinder the estimation of the mortality burden associated with the COVID-19 pandemic. During a public health emergency, estimating all cause excess deaths above an expe...

Open AccessCOVID-19 case fatality risk by age and gender in a high testing setting in Latin America: Chile, March–August 2020
Early severity estimates of coronavirus disease 2019 (COVID-19) are critically needed to assess the potential impact of the ongoing pandemic in different demographic groups. Here we estimate the real-time dela...

Open AccessEvaluating the potential impact of targeted vaccination strategies against severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV) outbreaks in the healthcare setting
Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS) are two coronaviruses with demonstrated potential to generate significant nosocomial outbreaks. In particular, MERS continue...

Open AccessA maximum curvature method for estimating epidemic onset of seasonal influenza in Japan
Detecting the onset of influenza epidemic is important for epidemiological surveillance and for investigating the factors driving spatiotemporal transmission patterns. Most approaches define the epidemic onset...

Open AccessAssessing parameter identifiability in compartmental dynamic models using a computational approach: application to infectious disease transmission models
Mathematical modeling is now frequently used in outbreak investigations to understand underlying mechanisms of infectious disease dynamics, assess patterns in epidemiological data, and forecast the trajectory ...

Chapter
Introduction
Infectious diseases ranging from respiratory (influenza, common cold, tuberculosis, the respiratory syncytial virus), vector-borne (plague, malaria, dengue, chikungunya, and Zika) to sexually transmitted (the ...

Chapter
Shapes of Hazard Functions and Lifetime Distributions
The main focus of this book is to address phenomenological questions regarding the spread of infectious diseases at the population level. Examples of such questions include:

Chapter
Behaviors of a Disease Outbreak During the Initial Phase and the Branching Process Approximation
We consider that at the beginning, t = 0, there is no disease. We call the system at this condition the disease-free equilibrium. We assume that the entire population is susceptible. The size of the susceptible p...

Chapter
More Complex Models and Control Measures
We have seen that, under suitable assumptions such as homogeneous mixing, the basic reproduction number R 0, defined at the start of the epidemic and given by (4.2

Chapter
Characterizing Outbreak Trajectories and the Effective Reproduction Number
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 p...

Chapter
Random Counts and Counting Processes
We now turn our attention to the population level dynamics and ask phenomenological questions. First, many important measures in the study of infectious diseases are count variables N, taking integer values n = 0...

Chapter
Beyond the Initial Phase: Compartment Models for Disease Transmission
We start with simple models that describe the dynamics of disease transmission over time t in a constant population of size m and investigate the long-term epidemic dynamics as t →∞. In these simple models, we as...

Chapter
Some Statistical Issues
All the models presented in the previous chapters are parametric. They belong to different types and serve different purposes.

Chapter
Mechanistic Models with Spatial Structures and Reactive Behavior Change
As we have emphasized in Chaps. 4 and 5, simple homogeneous models of transmission or growth dynamics often yield an early exponential epidemic growth phase even when the population is stratified into differen...

Open AccessEstimating the subcritical transmissibility of the Zika outbreak in the State of Florida, USA, 2016
Florida State has reported autochthonous transmission of Zika virus since late July 2016. Here we assessed the transmissibility associated with the outbreak and generated a short-term forecast.

Open AccessModel estimates of the burden of outpatient visits attributable to influenza in the United States
Although many studies have modelled the national burdens of hospitalizations and deaths due to influenza, few studies have considered the outpatient burden. To fill this gap for the United States (US), we appl...
