Definitions
A field of science that studies health problems within populations.
what is Epidemiology?
Something that belongs to a particular people or population. It means natural to or native to, confined to or widespread only within a place or pop of people.
What is an Endemic?
Is an individual with no overt disease who harbors infectious organisms. Dissemination is the spread of the organism in the environment.
What is a Carrier?
an instance of a particular situation; an example of something occurring.
What is Case?
is an individual with no overt disease who harbors infectious organisms. Dissemination is the spread of the organism in the environment.
What is a Carrier?
The ability to produce a desired or intended result.
What is Efficacy?
Sudden increase in number of cases of a disease above the normally expected level within a community, pop, or region. Significantly higher.
What is an Epidemic?
One who harbors a pathogenic organism for a clinically significant time and is able to pass the infection to others.
What is an Active Carrier?
the person who first brings a disease into a group of people.
What is a Primary Case?
When the infection spreads from one person to another.
What is Propagated?
The degree to which something is successful in producing a desired result; success.
What is Effectiveness?
An epidemic that has spread over multiple countries or continents and usually affects a large number of people.
What us a Pandemic?
Those who never experience symptoms despite being infected.
What is a Healthy or Passive Carrier?
A person who gets a disease from exposure to a person with the disease, or primary case.
What is a Secondary Case?
Is one in which a group of persons are all exposed to an infectious agent or a toxin from the same source.
What is Common-Source?
Characterization of the distribution of health-related states or events.
What is Descriptive Epidemiology?
More-than-expected increase in the number of endemic cases. Can be single area.
What is an Outbreak?
One who harbors and spreads an infectious organism during the incubation period of a disease before it becomes clinically evident.
What is an Incubatory Carrier?
No laboratory evidence but clinical signs and symptoms.
indirect transmission of an infectious agent that occurs when a vehicle (or fomite) touches a person's body or is ingested.
What is Vehicle-Borne Transmission?
A 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?
Pattern of a common-source outbreak followed by secondary person-to-person spread is not uncommon.
What is a Mixed-Epidemic?
One who harbors an infectious organism, e.g., methicillin-resistant Staphylococcus aureus in the nasal passages, from time to time but not continuously.
What is an Intermittent Carrier?
May indicate the source of the disease, the possible spread, and which reservoir holds the disease in-between outbreaks.
What is an Index Case?
Shows the process through which infectious disease transmission occurs. The pathogen, or infectious agent, leaves the reservoir through a portal of exit.
What is a Chain of Infection?
