Intro to Epidemiology
Conditions that lead up to the health outcomes
What is cause
Droplet/dust particles carry the pathogen to the host and cause infection, i.e: sneezing, coughing.
What is airborne transmission?
Prevent disease before it spreads.
Individual who has been exposed to the disease-causing organism but have been able to recover from the disease.
A person in a community who has been confirmed for having a certain disease, disorder, injury, or condition.
What is a case?
Human or animal that is susceptible to the disease.
What is a host?
Instant transfer of an infectious agent from one person to another by physical contact.
What is direct transmission?
Requires behavior changes such as exercising, stop smoking, and diet changes.
What is active primary prevention?
Habitat which an infectious agent lives, grows, doubles and determines it survival rate in nature.
What is an active carrier?
Someone who has all the signs and symptoms of a disease but it has not been officially diagnosed.
What is suspect case?
The outcome of a program that produces an effect on people who are in the program vs. those who are not.
What is efficacy?
The agent is transferred or carried by an organism resulting in disease, i.e: water, food, and oral contact.
Not requiring behavior change, eating enriched foods high in vitamins.
What is passive primary prevention?
An infected person who spreads and contains an infectious organism.
What is carrier?
Virus, bacteria, fungus or parasite is all examples of what?
What is a pathogen?
The study of distributing health-related events in the human populations and application of this study to the prevention and control of health problems.
What is epidemiology?
Occurs when an arthropod (ex: flea, tick) conveys the infectious agent.
Health screening and early detection to create a potential cure to reduce disability or death.
What is secondary prevention?
A person who has been exposed to the pathogen but does not become ill or show symptoms of the disease.
What is healthy carrier?
First disease case sought out by an epidemiologist.
What is an index case?
Name the types of epidemiology:(1)involves characterization of the distribution of health-related events, (2)testing hypothesis, and identifying causes of health-related situations.
What is descriptive and analytical epidemiology?
The pathogen undergoes a change as part of a life cycle within a host/vector before being transmitted to a new host.
What is biological transmission?
Making rehab accessible where the disease and injury have already occurred and caused damage.
What is tertiary prevention?
A person who is exposed and maintains a pathogen and spreads the disease in different places and settings.
What is intermittent carrier?
Looking at several factors that have effective measures
