Epidemiology Triangle
Infectious Agent
What is cause
This studies measure the association between a particular exposure and a disease, using information collected from individuals, rather than from the aggregate population.
What is Analytic Epidemiology
This aims to describe the distributions of diseases and determinants
What is descriptive epidemiology
a widespread occurrence of an infectious disease in a community at a particular time.
What is an epidemic
these are humans; possibly monkeys
What is a Reservoir
Impact opportunity for exposure
what is the environment
this is defined broadly to include behavioral factors such as smoking or diet, environmental pollutants such as asbestos,
What is exposure
Some of these changes occur regularly, while others are unpredictable
What is time
This is of a disease or condition regularly found among particular people or in a certain area.
What is an endemic
This pathogen leaves via the skin of an infected person through a mosquito bite
What is the portal of exit
Impact exposure susceptibility and response
What is host
This Test hypotheses and Answers questions like why and how
What is analytic epidemiology
This describes the occurrence of disease by place provides insight into the geographic extent of the problem and its geographic variation.
What is place
This is of a disease prevalent over a whole country or the world.
What is a pandemic
This is the indirect transmission to humans by mosquito vector
What is the Mode of transmission
Acute blood loss during the collection of routine laboratory tests.
What is an agent
pertaining to or emanating from analysis and the study of the patterns, causes, and effects of health and disease conditions in defined populations.
What is analytic Epidemiology
This is probably the single most important “person” attribute, because almost every health-related event varies with it
What is age
occurring at irregular intervals or only in a few places; scattered or isolated.
What is sporadic
This is a pathogen is transmitted through skin into blood through a mosquito bite
What is portal of entry
Physical aspects like climate, biologic aspects like animals transmitting agents and socioeconomic factors like crowing or lack of sanitation.
What is the environment.
The two most common study designs in analytic epidemiology
What are cohort and case-control
This is used to estimate the number of people affected by a given disease, or with relevant health characteristics, including symptoms and signs, at a population level
What is descriptive epidemiology
the sudden or violent start of something unwelcome, such as war, disease,
What is an outbreak
An infectious agent may be transmitted from its natural reservoir to a susceptible host in different ways
What is mode of transmission
