Epidemiology is the study and analysis of the distribution who, when, and where , patterns and determinants of health and disease conditions in defined populations. It is a cornerstone of public health , and shapes policy decisions and evidence-based practice by identifying risk factors for disease and targets for preventive healthcare. Epidemiologists help with study design, collection, and statistical analysis of data, amend interpretation and dissemination of results including peer review and occasional systematic review.

This chapter outlines the ethical issues raised by the use of genomics in the study of infectious disease, in research and development of preventive and therapeutic measures, and to inform public health interventions and policies. More than two decades of ethical, legal, and social implications ELSI research on the application of genomics to complex diseases have produced many insights that are also relevant to infectious diseases; however, a number of factors unique to infectious diseases underscore the importance of identifying novel ELSI issues that might emerge from the application of genomics in this context, including issues surrounding personalized medicine and public health. While the science of genomics in the context of infectious disease is still in its infancy, and it is too early to identify all of the potential ELSI issues that may emerge from it, policy recommendations for public health strategies to prevent and control infectious disease must attend to such concerns. Keywords: genomics , personalized medicine , infectious disease , ELSI , public health ethics. Scientific advances in genomics can elucidate infectious disease pathology, immunology, and vaccinology; augment research and development of preventive and therapeutic measures; and enhance the efficiency of public health interventions and policies Eisen and MacCullum, ; Telenti, ; Trautmann and Sekaly, ; Omenn, ; Pang, ; Yan, , —; Yang et al.

Epidemiology Research Guide

Hardly a day goes by without news headlines concerning infectious disease threats. For an evidence-based and responsible communication of infectious disease topics to avoid misunderstandings and overreaction of the public, we need solid scientific knowledge and an understanding of all aspects of infectious diseases and their control. The aim of our book is to present the reader with the general picture and the main ideas of the subject. The book introduces the reader to methodological aspects of epidemiology that are specific for infectious diseases and provides insight into the epidemiology of some classes of infectious diseases characterized by their main modes of transmission. This choice of topics bridges the gap between scientific research on the clinical, biological, mathematical, social and economic aspects of infectious diseases and their applications in public health. The book will help the reader to understand the impact of infectious diseases on modern society and the instruments that policy makers have at their disposal to deal with these challenges.

PLOS Medicine 2 8 : e Mathematical models have become invaluable management tools for epidemiologists, both shedding light on the mechanisms underlying observed dynamics as well as making quantitative predictions on the effectiveness of different control measures. Here, we explain how substantial biases are introduced by two important, yet largely ignored, assumptions at the core of the vast majority of such models. First, we use analytical methods to show that i ignoring the latent period or ii making the common assumption of exponentially distributed latent and infectious periods when including the latent period always results in underestimating the basic reproductive ratio of an infection from outbreak data. We then proceed to illustrate these points by fitting epidemic models to data from an influenza outbreak. Finally, we document how such unrealistic a priori assumptions concerning model structure give rise to systematically overoptimistic predictions on the outcome of potential management options.

Modern Infectious Disease Epidemiology

This page covers the basic principles of epidemic theory. The basic reproduction number R 0 is used to measure the transmission potential of a disease. It is the average number of secondary infections produced by a typical case of an infection in a population where everyone is susceptible. R 0 excludes new cases produced by the secondary cases.

Infectious diseases are directly responsible for approximately 1 in 4 deaths globally.
