Chain of Infection
Shows the process through which infectious diseases transmission occursChain of infection
What is chain of infection?
Focuses on preventing the disease before it develops
What is primary prevention?
Physical contact between an infected person and a susceptible person
What is direct transmission?
An infected individual who can transmit the disease to others
What is an active carrier?
A field of science that studies health problems within populations
What is epidemiology?
Ways infectious disease can transmit to others
What is modes of transmission?
Requires behavior change on part of subject
What is active primary prevention?
No direct human-to-human contact
What is indirect transmission?
Those who never experience symptoms despite being infected
What is a passive carrier?
A disease that affects the global population that is caused by new infectious agents that spread quickly
What is pandemic?
The habitat in which the infectious agent normally lives, grows, & multiplies
What is a reservoir?
Those that do not require action by an individual for protection to occur
What is passive primary prevention?
Bacteria or viruses that are transmitted through small respiratory droplets
What is airborne transmission?
Those who have recovered from their illness but remain capable of transmitting to others
What is convalescent carrier?
An unexpected increase in the number of infectious diseases that spread rapidly within a community, population, or region
What is epidemic?
The place where the organism leaves the reservoir
What is portal of exit?
Attempts to detect a disease early and intervene early
What is secondary prevention?
Transfer of pathogen from an infected host to a susceptible host
What is mechanical transmission?
Those who can transmit the agent during the incubation period before illness begins
What is incubatory carrier?
A characterization of the distribution of health related states or events
What is descriptive epidemiology?
The opening where an infectious disease enters the host's body
What is portal of entry?
Directed at managing established disease in someone and avoiding further complications
What is tertiary prevention?
A disease that undergoes maturation in an intermediate host before it can be transmitted to humans
What is biological transmission?
An individual that shows no systems of a disease but harbors the infectious agent and is capable of transmitting it to others
What is intermittent carrier?
Measures the association between a particular exposure and disease using quantifiable data from individuals
What is analytic epidemiology?
