What is epidemiology of infection?
Epidemiology is the study of the determinants, occurrence, and distribution of health and disease in a defined population. Infection is the replication of organisms in host tissue, which may cause disease.
What role does epidemiology play in infectious disease?
Epidemiologists are interested in virus spread or transmission, with or without disease. Viral epidemiologists try to predict the potential for development of epidemics, and a very important part of their job is to define the kinds of interventions that could contain a virus outbreak.
What are the three factors of the epidemiological triangle?
Among the simplest of these is the epidemiologic triad or triangle, the traditional model for infectious disease. The triad consists of an external agent, a susceptible host, and an environment that brings the host and agent together.
How do epidemiologists classify infectious diseases?
Epidemiologists usually classify infectious diseases according to two important epidemiologic characteristics—their means of transmission and the reservoir of the organism.
What are 3 types of studies used in epidemiology?
The basic epidemiological study designs are cross-sectional, case-control, and cohort studies.
What are the 2 major categories for epidemiological studies?
Epidemiologists conduct two main types of analytic studies: experimental and observational. Experimental studies use a randomized selection process. A process based on chance is used to assign study subjects to different exposure groups.
What are the two main types of epidemiologic methods?
Epidemiologic studies fall into two categories: experimental and observational.
What is the difference between epidemiology and clinical epidemiology?
Whereas much of population epidemiology is directed towards the general population, clinical epidemiology is more focused on the individual.
What are the basic principles of epidemiology?
Basic epidemiologic methods tend to rely on careful observation and use of valid comparison groups to assess whether what was observed, such as the number of cases of disease in a particular area during a particular time period or the frequency of an exposure among persons with disease, differs from what might be …
What are the basic concepts of epidemiology?
Two essential concepts of epidemiology are population and comparison. Core epidemiologic tasks of a public health epidemiologist include public health surveillance, field investigation, research, evaluation, and policy development.
What is epidemiology and infection?

Why study evolutionary biology in infectious disease epidemiology?
Infectious disease epidemiology is a practical science, concerned with minimizing the impact of pathogens on public health. As both pathogens and their hosts have evolved, evolutionary biology is relevant to understanding the nature of their interactions for fitness, and also in resolving the history of pathogen transmission.
How is open access publishing in epidemiology&infection funded?
Open access publishing in Epidemiology & Infection is funded through levying an article processing charge (APC) on each individual author’s institution or funding body. An APC of £1,870 / $2,980 will apply to all accepted papers, with a waiver scheme for eligible countries – see waiver policy below for more details.
