What is epidemiology?
preventing disease/disorder before it happens
What is primary prevention?

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?

What is the suspect's case?
infection transmitted to humans and other animals by blood-feeding anthropods, such as mosquitoes, ticks,

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?
