Basics
A field of science that studies health problems within populations.
What is epidemiology?
A human in which disease occurs.
What is the host?
This level of prevention may include rehabilitation.
What is tertiary prevention?
An infected person who shows no evidence of clinical disease ban can still infect others?
What is a carrier?
What is the mode of transmission?
This model contains the elements of host, agent, and environment.
A non contagious or contagious power that causes a health concern.
What is the agent?
If primary prevention is used during prepathogenesis or incubation stage, then this level of prevention is used when the host begins to react to the agent.
What is secondary prevention?
Humans, animals, plants, soil in which infectious agent normally lives and multiplies.
What is reservoir?
This involves contact between a person with the disease and another person.
What is direct transmission?
Involves characterization of the distribution of health related states or events.
What is descriptive epidemiology?
First infected or source of the outbreak in a population.
Inanimate intermediary in the indirect transmission of an agent that carries the agent from a reservoir to a susceptible host.
What is vehicle?
Made up of links in sequential order, which include include - agent, reservoir, mode of transmission, portal of entry, and host.
It shows characteristics of both common source and propagated epidemics (it is often caused by foodborne infectious agents).
What is mixed epidemic?
According to the epidemiology model, this is needed for disease to happen.
What is the interaction of the agent, host, and environment?
The first documented patient in the onset of an epidemiological investigation.
Attacks the population of people and may spread through countries and several communities.
What is epidemic?
Transmission that includes a vehicle or vector such as air borne, or contaminated water.
What is indirect contact?
Involves finding and quantifying, testing hypothesis and identifying causes of health related states or events.
What is analytic epidemiology?
What is fomite?
A case with any fertile illness accompanied by a rash
What is a suspect case?
An outbreak of disease that attacks people at the same time.
What is pandemic?
Transfer of infectious agent from a vector's body to the host.
What is a mechanical vector?
