A field of science that studies health problems within populations
What is Epidemiology?
Factors include host, agent, environment, and time
What is the Epidemiological Triangle?
A person who has been exposed to and harbors a pathogen and who has done so for some time
What is an active carrier?
the uninterrupted and immediate transfer of an infectious agent from one person to another
What is direct transmission?
This occurs at irregular intervals, in a scattered and isolated manner and without geographical concentration
What is sporadic?
What is in vitro?
This shows the process through which infectious disease transmission occurs
What is the chain of infection?
A person who harbors a pathogen who is also in the recovery phase of the course of the disease but is still infectious.
What is a convalescent carrier?
when an agent is transferred or carried by some intermediate item, organism, means, or process to a host, resulting in disease
What is indirect transmission?
This belongs to a particular person or population. It means "native to" or " natural to." Usually happens at a low level in a population within the confines of a geographical region.
This type of research is done on animals
What is in vivo?
This requires behavior change in the individual
What is active primary prevention?
A person who has been exposed to and harbors a pathogen but has not become ill or shown any of the symptoms of the disease
What is a healthy carrier?
droplets or dust particles carry the pathogen to the host and cause infection
What is airborne transmission?
This is more than an expected increase in the number of endemic cases. But can also be a single case in a new geographical area. Can be turned in to an epidemic if not controlled.
What is outbreak?
a person in a population who has been identified as having a particular disease, disorder, injury, or condition.
What is a case?
The pathogen or disease-causing agent enters the body through this
What is the portal of entry?
Someone who has been exposed to a pathogen, is in the beginning stages of the disease, is displaying symptoms, and also has the ability to transmit the disease
What is a incubatory carrier?
an arthropod such as a mosquito, flea, tick, or lice conveys the infectious agent (responsible for carrying the disease)
What is vector-borne transmission?
What is an epidemic?
an inanimate (nonliving) object such as a piece of clothing, a door handle, or a utensil that can harbor an infectious agent and is capable of being a means of transmission
What is fomite?
limiting any disability by providing rehabilitation when a disease, injury, or disorder has already occurred and caused damage
What is tertiary prevention?
Someone who has been exposed to a pathogen and can spread the disease in different places or at different intervals
What is a intermittent carrier?
an inanimate object that conveys an infectious agent to a host such as sharing drinking water or in swimming pools, etc.
What is vehicle-borne transmission?
This spreads over multiple countries or continents and affects a large number of people.
What is a pandemic?
