Chain of Infection
Cause of disease
What is the infectious agent
Limiting any disability by providing rehabilitation when disease, injury, or disorder has already caused damage
What is tertiary prevention
occurrence of cases of an illness, specific health-related behavior, or other health-related events clearly in excess of normal expectancy in a community or region
What is an epidemic?
Immediate transfer of an infectious disease from one person to another
Individual who carries a pathogen and is in a recovery stage and still infectious
What is a convalescent carrier?
When the pathogen leaves this source disease transmission occurs
What is the reservoir?
Lifestyle changes, community health education, school health education, safe and healthy conditions at home
What is primary prevention
The flu being consistent from year to year
What is an endemic?
Pathogens carried through a building's heating or air-conditioning ducts
What is airborne transmission
An infectious organism that can be transmitted from animals to humans
What is zoonosis
After the pathogen leaves the reservoir there are two types of this
Slows the progress of disease
What is secondary prevention
Extent of COVID-19 virus
What is a pandemic
Carried through mosquito, flea, tick, or lice as the infectious agent
What is vector-borne transmission?
A fomite, food, or water that conveys the infectious agent from a reservoir to a vulnerable host
What is a vehicle?
Two ways in which a pathogen interacts with a host
Any attempt to restore an afflicted person back to a productive lifestyle
What is rehabilitation
Initial phase occurs more rapidly
What is a common source epidemic?
What is biological transmission?
An object capable of carrying an infectious agent
What is a fomite
Mucous membranes, wounds
What is the portal of entry?
Does not require behavior change on the part of the individual
What is passive primary prevention?
Tuberculosis, whooping cough, flu, and measles
What is a propagated epidemic?
Pathogens like cholera is carried in drinking water, swimming pools, streams, or lakes used for swimming
What is vehicle-borne transmission
The environment allows the agent and host to interact
What is the epidemiologic triangle
