Definitions
refers to the constant presence and/or usual prevalence of a disease or infectious agent in a population within a geographic area.
Endemic
an indirect transmission process during which the pathogen is indirectly transferred from a reservoir, source or host to another host by inanimate intermediary vehicle objects
Vehicle-borne transmission
the 4 factors of the Epidemiology triangle
host, agent, environment, and time
intervening before health effects occur, through. measures such as vaccinations, altering risky behaviors
Primary prevention
more than the expected increase in the number of endemic cases limited to geographic areas
Outbreak
A field of science that studies health problems within populations
Epidemiology
infections transmitted by the bite of infected arthropod species, such as mosquitoes, ticks, triatomine bugs, sandflies, and blackflies.
Vector-borne transmission
This cycle shows the process through which infectious disease transmission occurs.
Chain of infection
taking regular exercise to prevent health problems developing in the future is an example of what kind of prevention
Active primary prevention
True or False: Epidemiology answers the questions who what, why, how, when
true
an epidemic that affects a region, country, or continent.
Pandemic
disease transmission through small particulates that can be transmitted through the air over time and distance.
Airborne transmission
pathogen leaves via the skin of an infected person through a mosquito bite
Portal of exit
strategies that do not require action by an individual for protection to occur; individuals are automatically protected, and even sometimes without their awareness is an ex of what kind of prevention
Passive primary prevention
what is a model of disease causation that helps us understand the interrelated nature of factors that contribute to disease.
Epidemiology triangle
occur in excess of what is normal, beyond the endemic level, in a community or region
Epidemic
occurs when there is no direct human-to-human contact.
indirect transmission
pathogen is transmitted through skin into blood through a mosquito bite
Portal of entry
trying to detect a disease early and prevent it from getting worse
Secondary prevention
True of False; the goal of pubic health is to improve the overall health of a population by preventing and controlling disease
True
show characteristics of both common source and propagated epidemics
mixed epidemic
occurs when there is physical contact between an infected person and a susceptible person.
direct transmission
5 steps of the Chain of infection cycle
Reservoirs
Portal of exit
Mode of transmission
portal of entry
Host will be susceptible
trying to improve your quality of life and reduce the symptoms of a disease you already have.
Tertiary prevention
True or False; Sporadic does not refer to only a few geographical places
false
