CHARACTERISTICS OF EPIDEMIOLOGY
A field of science that studies health problems within populations
What is Epidemiology
a widespread occurrence of an infectious disease in a community at a particular time
What is Epidemic
is a model for explaining the organism causing the disease and the conditions that allow it to reproduce and spread
What is Epidemiology triangle
is the route or method of transfer by which the infectious microorganism moves or is carried from one place to another to reach the new host.
What is Modes of Transmission
is a person or other organism that has inherited a recessive allele for a genetic trait or mutation but usually does not display that trait or show symptoms of the disease.
What is a Carrier
studies measure the association between a exposure and a disease, using information collected from individuals, rather than from the aggregate population.
What is Analytic Epidemiology
occurring over a wide geographic area and affecting an exceptionally high proportion of the population.
What is Pandemic
objects or materials which are likely to carry infection, such as clothes, utensils, and furniture.
What is Fomite
when there is physical contact between an infected person and a susceptible person
What is Direct transmission
is the gradual recovery of health and strength after illness or injury.
What is Convalescent carrier
Describes the pattern of disease occurrence in terms of time, place, person
What is Descriptive Epidemiology
regularly found among particular people or in a certain area.
What is Endemic
is an organism that does not cause disease itself but which spreads infection by conveying pathogens from one host to another
What is Vector
transmission refers to situations where a susceptible person is infected from contact with a contaminated surface
What is Indirect Transmission
those who can transmit the agent during the incubation period before clinical illness begins.
What is Incubatory Carrier
the ability to produce a desired or intended result.
What is Efficacy
the affected individuals had an exposure to a common agent.
What is Common-source
Any person, animal, plant, soil or substance in which an infectious agent normally lives and multiplies.
What is Reservoir
when bacteria or viruses travel on dust particles or small respiratory droplets that become aerosolized when an infected person sneezes or coughs.
What is Airborne Transmission
individuals who have been exposed to and harbor a pathogen and who can spread the disease at different places or intervals
What is Intermittent Carrier
is the capability of producing a desired result or the ability to produce desired output
What is Effectiveness
is a person or other organism that has inherited a recessive allele for a genetic trait or mutation but usually does not display that trait or show symptoms of the disease.
What is a Carrier
a disease that can be transmitted from animals to people
What is Zoonosis
human illnesses caused by parasites, viruses and bacteria that are transmitted by mosquitoes, sandflies, triatomine bugs, blackflies, ticks, tsetse flies, mites, snails and lice.
What is Vector-borne transmission
transmission refers to situations where a susceptible person is infected from contact with a contaminated surface
What is Indirect transmission
