studies health problems within populations
What is epidemiology?
preventing disease/disorder before it happens
What is primary prevention?
the first disease in the population
What is the primary case?
physical contact between an infected person, there is no direct human-to-human contact.
What is direct and indirect?
the an infection that can lead to a disease
what is an infectious agent?
Analytic ( finding the causes) and descriptive( describing the distribution)
What is the 2 diff. methods of epidemiology?
health screening and detect to identify disease.
What is secondary prevention?
those who get sick after the disease have been introduced and been in contact with the primary case
What is the secondary case?
the spread of an infectious agent caused by the dissemination of droplet nuclei
What is airborne transmission?
humans:possibly monkeys: where it stays
What is the reservoir?
a program's ability to produce the desired effect and program's ability to produce benefits.
active( requires invidivdual) and passive (doesnt).
What is the 2 primary prevention?
an individual who has signs/symptoms of a disease but not confirmed yet.
What is the suspect's case?
infection transmitted to humans and other animals by blood-feeding anthropods, such as mosquitoes, ticks,
What is vector-borne transmission?
pathogen leaves via the skin, of an infected person through a mosquito bite.
What is a portal of existing?
Endemic= disease at given location/pop. Epidemic= rapid rise Pandemic=spread across the globe
what are the 3 emics?
to block the progress of disability/condition/disorder that already occurred.
what is tertiary prevention?
first disease case brought to the epidemiologist's attention.
What is the index case?
Transmission through a contaminated source. and Transfer of pathogens from an infected host or a contaminated substrate to a susceptible host
What is Vehicle-borne vs. Mechanical?
pathogen transmitted through the skin into the blood through a mosquito bite.
what is the port of entry?
victim of common source epidemic have p-to-p contact and spread it.
What is a mixed epidemic?
an attempt to bring back someone to a normal lifestyle.
What is Rehabilitation?
Case( identified as having a disease) and ensures cases are consistently diagnosed.
when the vector uptakes the agent, usually through a blood meal from an infected animal, replicates and/or develops
Biological transmission
susceptible and gets sick except for survivors of a previous who are immune to it
what susceptible host?
