Outbreak Investigation
This is how you conduct a case-control study, generally
The study of the distribution and determinants of health-related states in specified populations, and the application of this study to control of health problems
What is epidemiology?
Dose, as involved in transmission
What is the amount of infectious agent that enters a susceptible person?
Phrenology, or the study of people's head shapes and sizes as an indication of their character and intelligence, is an example of this
What is a pseudoscience?
Mortality
Total deaths from any cause in a given year in a population/ Average total population for the same year
What is crude mortality rate?
A disease that moves between animals and humans
What is a zoonosis?
Latency Period
What is the amount of time before an infected person becomes infectious?
This can move between an agent and host, causing spread of the disease.
What is a vector?
His personality changed after a railroad spike was driven through his head
Who was Phineas Gage?
Morbidity:
Number of people with a disease in a population at one point in time/ Total in the given population at same point in time
What is prevelance? ie prevelance of HIV in IV drug users
One case of any of these is considered an outbreak.
What are anthrax, smallpox, plague, or botulism?
Incubation Period
What is the amount of time a disease is in you before you start showing symptoms?
Touching, skin to skin contact, and sexual intercourse.
What are types of direct transmission?
This is a danger when you use anecdotal data to form your beliefs.
What is Confirmation Bias
Morbidity
Number of new cases of a disease in population in given time (1 year)/ Average total population in same time period multiplied by the amount of time they are at risk
What is incidence
3 components of a case definition.
What are location, symptoms, lab diagnosis, or timing?
A disease that has bats as a reservior
So many to choose from
Transmission that includes a vector or vehicle such as contaminated water, or air borne.
What is indirect contact?
I think I had the cake yesterday- yes, I'm sure it was yesterday
What is Recall bias
Mortality
Total deaths from a specific cause in a year in a population subgroup/ Average total population subgroup for the same year
What is cause-specific mortality rates?
A geographical location wherein people have an unusually high life expectancy
What is a blue zone?
What is R0 or the basic reproductive rate?
What is a measure of the number of infections produced on average by an infected individual in the early stages of an epidemic.
The difference between airborne and droplet
What is that droplets are larger, last for a shorter time and/or are a less infectious method of transmission
Why was Andrew Wakefield's post-study press conference unethical?
Because he stated that his "case-control" study absolutely showed cause.
Mortality:
Total deaths of infants in given year in population/ Total # of live births in same year in population
What is infant death rate
