What is a case?

100

Direct and indirect transmission are two general ___

What are modes of transmission?

100

Stopping a disorder or disease before it occurs

What is primary prevention?

100

Contains, spreads, or harbors and infectious organism

What is a carrier?

100

A filed of science that studies health problems within specific populations

What is epidemiology?

200

A standard set of criteria that ensures that cases are consistently diagnosed, regardless of when or where they were identified and who diagnosed the case

What is case definition

200

The immediate transfer of an infectious agent from one individual to another 

What is direct transmission?

200

Requires an individual to produce a change of behavior 

What is active primary prevention?

200

Someone who has been exposed to and harbors a disease-causing organism and has done so for some time, even if the person may have previously recovered from the disease

What is an active carrier?

200

This occurs when victims of a common-source epidemic have person-to-person contact with others, resulting in the spread of disease

What is a mixed epidemic?

300

The first documented disease case in a population during an epidemic 

What is a primary case?

300

When an agent is transferred or carried by an item, organism, means, or process to a susceptible host, resulting in disease

What is indirect transmission?

300

Does not require a change of behavior of the individual 

What is passive primary prevention?

300

Someone who harbors a pathogen and although they may be in the recovery phase of the disease, is still infectious

What is a convalescent carrier?

300

An epidemic affecting or attacking the population of an extensive region, country, or continent, or in our modern day; the world 

What is a pandemic?

400

The individuals who become infected and ill after a disease has been introduced into a population 

What are secondary cases?

400

Occurs when dust particles or droplets carry the pathogen to the host; causing infection 

What is airborne transmission?

400

Aimed at the health screening and detection activities used to identify disease

What is secondary prevention?

400

Someone who has been exposed to and harbors a pathogen, but has not fallen ill or shown any of the symptoms of the disease

What is a healthy carrier? (or passive carrier)

400

Refers to the ongoing and constant presence of a disease in a community or among a group of people; what we will be witnessing in our daily lives for at least the next year

What is an endemic?

500

Someone who has all of the signs and symptoms of a disease or condition, yet has not been diagnosed as having it 

What is a suspect case?

500

When a pathogen undergoes changes as part of its life cycle while still within the host vector and before transmission to the new host

What is biological transmission?

500

The aim of the third level of prevention is to block the progression of a disability, condition, or disorder in order to keep it from advancing

What is tertiary prevention?

500

Someone who has been exposed to and harbors a pathogen AND can spread the disease in different places 

What is an intermittent carrier?

500

Occurs when victims of a common-source epidemic have person-to-person contact with others and spread the disease, resulting in a propagated outbreak

What is a mixed epidemic?
