Factors of Epidemiology
The characterization of the distribution of health-related states or events.
What is Descriptive Epidemiology?
The environment in which the agent generally lives. Humans, animals, and the environment are all part of the reservoir.
What is a Reservoir?
When an infected individual interacts or exchanges bodily fluids with another, the transmission of the disease occurs.
What is Direct Transmission?
To keep a disease from reoccurring. It requires actions that reduce risk exposure or strengthen the immunity of persons at risk in order to prevent a disease from advancing to illnesses in a vulnerable individual.
What is Primary Prevention?
A collection of criteria is used to determine if a person has a disease or a health condition of interest, which helps when assessing the scope of illness in a community.
What is a case?
Using information gathered from individuals, assess the relationship between a certain exposure and a disease.
What is Analytic Epidemiology?
The path by which a pathogen leaves its host. The portal of exit usually is where the pathogen is introduced such as an injury or infection.
What is the Portal of exit?
Transmission of an infection from one person to another through an agent such as air, water, or a contaminated surface where the disease is living.
What is an Indirect transmission ?
Where an individual's behavior change such as exercising or quitting smoking, to reduce the cause of an illness.
What is Active primary prevention?
refers to the person who introduces a disease into a group of people and transmits from human to human.
What is Primary Case?
The area of medicine concerned with the occurrence, distribution, and potential control of illnesses and other health-related variables.
What is Epidemiology?
An infectious agent can be transferred from its natural reservoir to a vulnerable host in a variety of ways. This includes airborne methods or direct contact.
What is Modes Of Transportation?
When viruses transfer through dust particles or small respiratory droplets, they can infect a host when an infected person sneezes, coughs, sneezes or exhales.
What is Airborne Transmission?
offers protection against infection, through antibodies with vaccines. Vaccines assist with immunity over a short period of time.
What is Passive Primary Transmission?
Persons who have the illness after being exposed to a primary case rather than the epidemic source.
What is a Secondary Case?
Composed of three components: agent, host, and environment, all of which contribute to large outbreaks.
What is Epidemiology Triangle?
Describes how a disease enters a vulnerable host. The entry point must allow access to tissues where the infection may grow.
What is Portal Of Entry?
Occurs when a vector absorbs the agent, through blood, infected animals or ingestion of infected food.
What is Biological transmission?
detecting the disease process early in order to prevent the development of overtime and reduce serious symptoms.
What is Secondary prevention?
a case is classed as suspected when it is a crucial component of epidemiological monitoring.
What is a Suspect Case?
Defined as the fast spread of disease to a large number of patients within a certain area in a short period of time.
What is an epidemic?
This is the organism that will be affected by the infectious illness that has progressed along the infection chain.
What is the host?
Virus hosts such as mosquitoes, fleas, and ticks may transmit an infectious agent to help the pathogen's development by transporting the pathogen to other hosts.
What is Mechanical Transmission?
Reduces the impacts of disease and impairment in the already ill by establishing assessment facilities where the chronically ill can acquire short-term medications when their normal source of treatment is disrupted.
What is Tertiary prevention?
The first documented patient in a disease outbreak within a population, or the first documented patient in an epidemiological investigation.
What is an Index Case
