Modes of Disease Transmission
The two general modes of transmission
What are direct and indirect transmission?
The reason a person becomes sick
What is an infectious agent?
Immunizations, protection of food, and infection control are all done at that level
What is primary prevention?
The infected person who harbors the infection
What is a carrier?
The germ
What is a pathogen?
This transmission does not cause the disease, but is responsible for transmitting the pathogen
What is Vector-borne transmission?
The way in which a germ is spread
What is mode of transmission?
self management is used at this level
What is tertiary prevention?
Does not cause disease itself, but can be part of the infectious process
What is a vector?
This case is not always the primary case
What is index case?
This type of transmission can happen through bodies of water (pools, streams, lakes)
What is vehicle-borne transmission?
Individuals with underlying chronic diseases fall into are this
What is susceptible host?
Changes in behavior are required in this level
What is active primary prevention?
Common routes of infection include hospital settings, clothing, and door handles.
What is a fomite?
Ensures consistency in diagnosis
What is case definition?
This transmission is symbolized by the pathogens change in life cycle before transmission to new host
What is biological transmission?
Water can act as this
What is a reservoir?
The goal of this level is block the progression of disease
What is secondary prevention?
Diseases and infection spread from animals to humans
What is Zoonosis?
Measured by several variables
What is case severity?
Droplets are sometimes classified as what type of transmission
What is direct transmission?
Infected skin may be involved in this step of the chain
What is portal of entry?
Patient education and aftercare are aspects of this component
What is rehabilitation?
These are the five traditional types of carrier
What are active carrier, convalescent carrier, healthy carrier, incubatory carrier, and intermittent carrier?
A person can have all of the signs and symptoms, but does not have the disease/infection
What is suspect case?
