Levels of Prevention
100

an epidemic affecting large populations globally 

What is a pandemic?

100

uninterrupted and immediate transfer of infectious agent from person to person

What is direct transmission?

100

someone who is infected as a result of contact with the primary case

What is a secondary case?

100

an infectious organism in vertebrate animals that can be transmitted to humans

What is zoonosis?

100
stopping the disease before it happens

What is primary prevention?

200

an epidemiological research method that collections information about who, what, where, and when the health-related event happened

What is descriptive epidemiology?

200
infectious agent transferred by an intermediate item, organism, means, or host

What is indirect transmission?

200

an individual with all the signs and symptoms of disease or conditions but hasn't been diagnosed

What is a suspect case?

200

person or animal that contains, spreads, or harbors an infectious organism

What is a carrier?

200
preventing the progression of a disease to a debilitating state, or preventing it from getting worse

What is secondary prevention?

300

type of epidemiological study method that identifies and quantifies associations, as well as test hypotheses

What is analytic epidemiology?

300

droplets or dust particles carry pathogen to host's respiratory system

What is airborne transmission?

300

first case brought to the attention of the epidemiologist

What is the index case?

300
the habitat in which an infectious agent lives grows, multiplies, and depends on for survival

What is a reservoir?

300

attempts to restore someone to a satisfying lifestyle following the debilitating affects of condition

What is rehabilitation?

400

a higher than-normal occurrence of an illness or health-related behavior in a community or region

What is an epidemic?

400

the pathogen spreads through a host a mechanism for ride or nourishment

What is mechanical transmission?
400

This ensures that cases are consistently diagnosed, regardless of where or when they were identified and who diagnosed them.

What is a case definition?

400

inanimate object that can harbor an infectious agent and can therefore transmit disease

What is a fomite?
400

behavior changes

What is active primary prevention?

500

usual, recurring illness or health-related state in a community over a given period of time

What is endemic?

500

pathogen undergoes lifecycle changes within host/vector before transmission to a new host

What is biological transmission?
500
a measure of severity found by looking at variables such as length of hospital stay, and how disabling or debilitating the illness or condition is

What is case severity?

500

an invertebrate animal transmitting infection by conveying infectious agent from one host to another (ex: mosquito)

What is a vector?

500
blocking the progression of a disability, condition, or disorder to keep it from requiring excessive care

What is tertiary prevention?
