Epidemiology
Basic science or foundation of public health.
What is Epidemiology?
The cause of the disease.
What is an agent?
Direct and immediate transfer of an infectious agent from one person to another.
What is Direct Transmission?
Common route of infection in a hospital.
What is a fomite?
First disease case in a population.
What is a priamary case?
Characterizations of the distrubution of health related states or events.
What is descriptive epidemiology?
Provides subsistence and lodging for a pathogen.
What is a host?
Air currents, dust particles, water, food, and oral-fecal contact.
What is Indirect Transmission?
Will not cause disease itself, but is part of the infectious process.
What is a vector?
Not always the primary case.
What is an index case?
A specific event, condition, or characteristic that procedes the health outcome which is necessary for it's occurence.
What is a cause?
Opportunity for exposure.
What is an enviornment?
Occurs when droplets are carried through a buidlings heating or air conditioning ducts.
What is Airborne Transmission?
Also called "Passive Carriers".
What is a healthy carrier?
Shows all signs and symptoms of a disease, but has not yet been diagnosed as having the disease.
What is a suspect case?
A behaviour, environmental exposure, or inherant human characteristic that is associated with an important health condition.
What is a risk factor?
An agent of an infectious disease.
What is a bacteria?
Does not cause the disease itself iself but is responsible for transmitting the pathogen to a host.
What is Vector-borne Transmission?
Infections that can be naturally transmitted between vertebrae animals and humans.
What is Zoonosis?
Measurment of how disabling or debilitating and illness is.
What is Case severity?
Finding and quantifying associations, testing hypothesis, and identifying health related states or events.
What is Analytic Epidemiology?
Incubation period or life expectancy of a host.
What is time?
Changes in a pathogens life cycle while within the host/vector before transferring to a new host.
What is Biological Transmission?
Has been exposed and harbors a pathogen, is in the begining stages of the disease, is displaying symptoms, and has the ablity to transmit the disease.
What is an icubatory carrier?
Person in a population that has been identified as having a particular disease, disorder, injury, or condition.
What is a case?
