Chain of Infection
100

a person who has harbored a pathogen for a significant time and may have recovered from the disease.

What is an active carrier?

100

Transmission that requires close contact with the infection host and immediately transfers the infectious agent.


What is direct transmission?

100

Aiming to prevent the disease or injury before it ever happens

What is primary prevention?


100

A field of science that studies health problems, events, and prevention within populations.

What is Epidemiology?


100

A specific infectious agent (such as a bacterium or virus) of disease.

What is a pathogen?

200

A person that harbors or has been exposed to the pathogen that's in its earlier stages and is beginning to show symptoms. They can also transmit the disease.

What is an incubatory carrier?

200

When the infectious agent is carried by an immediate object. For example, water or food. This can transfer to the host.


What is indirect transmission?

200

Using detection and health screenings to identify the disease

What is secondary prevention?


200

The host, the agent, the environment, and time.

What is epidemiology triangle?

200

A natural environment that the pathogen requires for its survival.

What is a reservoir?

300

Contaminated with the pathogen and can transmit it to another host, but doesn't show symptoms.

What is a healthy carrier?

300

when bacteria or viruses travel on dust particles or small droplets when people sneeze, laugh, exhale, or cough.

What is airborne transmission?


300

Aiming to block the impact of an illness or injury from advancing.

What is tertiary prevention?

300

A constant presence of a disease in a community or among a group of people but case numbers stay the same.

What is endemic?


300

takes place in one of three ways, penetration, inhalation, or ingestion.

What is the portal of entry?

400

One that harbors the pathogen and can spread the pathogen in different places or times.

What is an intermittent carrier?

400

when an arthropod doesn't cause the disease it carries it.

What is vector-borne transmission?


400

Doesn't require behavior change on the individual in order to prevent a disease or disorder from occurring

What is passive primary prevention?


400

When epidemics occur at several different continents (global spread)


What is a pandemic?

400

Pathogen needs to leave the reservoir. For example, in humans it may be saliva, feces, or discharges

What is a portal of exit?

500

A person who recovered from infectious disease but is still capable of transmitting the infectious agent to other hosts.


What is the convalescent carrier?

500

An inanimate object transfer the infectious agent. For example a swimming pool

What is vehicle-borne transmission?


500

Requires behavior change on the individual. 


What is active primary prevention?

500

A type of disease passes from an animal or insect to a human.

What is zoonosis?

500

Pathogen can be transmitted either directly or indirectly


What is the mode of transmission?
