Case concepts
100

Prevention that aims to prevent a disease, infection, or injury before it happens 

What is primary prevention?

100

An invertebrate animal that transmits infections from one host to another. 

What is a vector? 

100

uninterrupted mode of transmission from one person to another 

What is direct transmission?

100

a carrier who has been exposed to a pathogen

What is an active carrier? 

100

a person in a population with a partivular disease, disorder, injury, or condition. identification of the person ensures consistency in diagnosis

What is a case? 

200

Primary prevention that requires a change in behavior of an individual 

What is active primary prevention?

200

a way of an infectious agent survives as in where it grows and multiplies 

What is a Reservoir?  

200

Transmission through a fomite or vector. 

What is Indirect transmission?

200

an asymptomatic carrier who‘s been exposed to a pathogen but has no symptoms 

What is a healthy carrier? 

200

in an epidemic, the first disease case in the population 

What is a primary case?

300

primary level of prevention that does not require individual behavior change(s). 

What is passive primary prevention?

300

a fomite that is an intermediary that transfers infectious agent from reservoir to a susceptible host (nonliving) 

What is a vehicle? 

300

transmission that occurs when droplets or dust particles carry the pathogen to the host 

What is an airborne transmission?

300

a carrier that harbors the pathogen and is still infectious in their recovery phase 

What is a convalescent carrier?

300

A person who has gotten infected from being in contact with the primary case. 

What is a secondary case? 

400

Level of prevention that aims to block disease progression.

What is secondary prevention?

400

An infectious organism in vertebrae animals that can be transmitted to humans through direct contact, a fomit, or a vector. 

What is zoonosis

400

Transmission of a pathogen driven by an arthropod 

What is a vector-borne transmission?

400

a carrier that has been exposed an has the pathogen during the beginning stage, and can transmit disease 

What is an incubatory carrier?

400

In an epidemic, this is the first disease case brought to the attention of the epidemiologist

What is an index case? 

500

level of prevention that block the progression of disability, condition, or disorder to prevent advancement. 

What is Tertiary prevention?

500

A non living item that can harbor an infectious disease and therefore be a mode of transmission 

What is a fomite? 

500

An inanimate object transmitting the pathogen or infectious agent to the host 

What is vehicle-borne transmission?

500

a carrier that has been exposed and harbors the pathogen, meaning that this carrier can spread the pathogen in different places or intervals. 

What is an intermittent carrier?

500

individual(s) with all the signs and symptoms of a disease or condition but hasn’t been diagnosed to be connected to a suspected pathogen. 

What is a suspect case?
