100

An outbreak where disease growth is exponential and widespread

What is a pandemic?

100

An individual directly exposed to the outbreak source who then spread the disease to others

What is a primary case?

100

An individual who carries an infectious agent or disease.

What is a carrier?

100

When a disease is transmitted through direct physical contact between an infected individual and a healthy individual.

What is direct transmission?

100

A method that prevents disease before it occurs

What is primary prevention?

200

A sudden increase of disease occurrence within a population or region

What is an epidemic?

200

An individual that contracts a disease from other previously infected individuals carrying the disease.

What is a secondary case?

200

A carrier who does not exhibit symptoms while infected

What is a passive carrier?

200

When a disease is transmitted indirectly through infectious droplets, germs, contaminated materials, and other exposure to infectious microorganisms.

What is indirect transmission?

200

A method that screens for or reduces the early impact of a disease or condition that has just occurred

What is secondary prevention?


300

Describes a disease or condition regularly present among a specific population or region

What is endemic?

300

The first documented patient of a disease outbreak

What is an index case?

300

Individuals who have recovered from a disease but still have the ability to infect others.

What are Convalescent carriers?

300

Transmission of disease commonly transmitted from insects to humans and other animals.

What is vector-borne transmission?

300

A method focused on rehabilitation and preventing the progression of disease after it has occurred.

What is tertiary prevention?

400

Describes an outbreak where infected individuals were exposed to a common agent

What is common-source?

400

A case that is currently awaiting laboratory confirmation on the presence of a disease within an individual that is exhibiting common symptoms.

What is a suspect case?

400

Individuals who can spread a disease during the incubation period before symptoms begin

What are incubatory carriers?

400

Transmission of disease specifically spread through infectious air particles and droplets that remain suspended in air.

What is airborne transmission?

400

A primary prevention method that does not require action by individuals for protection against a disease or condition to be present.

What is passive primary prevention?

500

Describes an outbreak where infected individuals spread disease from person to person

What is propagated?

500

A standardized set of criteria that classifies if an individual carries a disease or is affected by a health condition.

What is a case definition?

500

Individuals who carry infectious agents from time to time but not in a continuous manner.

What are intermittent carriers?

500

Transmission of disease where the infectious agent must develop/incubate within the vector before transmission.

What is biological transmission?

500

A primary prevention method that does require action by individuals for protection against a disease or condition to be present. Ex: lifestyle changes

What is active primary prevention?
