1. What are the three crit- safe air quality conditions, safe water supplies, and safe soils in a nations
ical areas of environ- farming industry
mental risk factors?
2. What do public health education, engineering, and enforcement
professionals use to re-
duce risk associated
with what we breathe
and ingest?
3. What is demography? studying person related variables in a population of interests over two or
more time periods with the goal of finding trends
4. What is life expectan- The average a number of years a newborn can expect to live at current
cy? mortality levels.
5. What are biostatistics? looks at variations in data between humans; helps us study health and
wellness
6. How are demography - helps us to understand epidemiology (incidence, distribution, and
and biostatistics signif- possible control) of diseases in various populations
icant in epidemiology? - if we can see trends in demography, biostatistics, mortality, and life
expectancy this can help us to better determine health inequities and
what we can do to provide equitable care on a population level
7. where do we get demo- census, community level data, national surveys
graphic data?
8. what variables are con- age, gender, and ethnicity
sidered demographic
data?

and what is the pur- - helps us to predict when/where/severity of a communicable disease so
pose of surveillance we can stop the disease process and protect more people
data collection of com-
municable diseases?
11. What is genomics? eth- - looking at the genetic epidemiology of diseases AKA genes that affect
ical dilemmas? if someone does or doesn't develop a disease
- protection against discrimination may be difficult
12. What is infectivity? how easily an organism causes disease
13. What is the difference infectivity is how easy people catch the disease, virulence is how sick it
between infectivity and makes the person
virulence? ex: colds have high infectivity but low virulence
14. What is the secondary number of new cases among contacts of new cases divided by total
attack/response rate? number of population at risk
ex: if four people at a retirement center tested positive for covid after
being exposed to a confirmed covid positive visitor and we divided it by
the total number of people in the retirement center unit without the covid
vaccine (50) we would get the secondary attack rate of 8%
15. What is the disease - number of accumulated cases of a disease including new and pre-ex-
prevalence? how is it isting at one time
calculated? - number of existing cases divided by the total people in a population
ex: 200 students at ABC college out of the total 600 students reported

having anxiety at some point since beginning college (200/600)= 33%
prevalence rate of anxiety in students at ABC college
16. What is the incidence number of NEW cases of a disease at a specific time or period of time
of a disease? divided by the total number at risk during that time
example: 10 students at ABC college out of the total 600 students tested
positive for the flu in the past three days (10/600)= 1.7% incidence rate
17. what is the main differ- prevalence includes new and old cases while incidence includes only the
ence between preva- new cases
lence rate and inci-
dence rate?
18. what are examples of interviewing healthcare providers, reviewing medical records, surveying
active surveilance? those exposed to an infectious agent
19. what are the three host: susceptible organism
VARIABLE components agent: biological (microbe/parasite), chemical (drugs/pesticides), nutri-
of the epidemiology tri- tive (cholesterol/fried foods), physical (natural disasters/car wrecks), or
angle? psychological (stress)
environment: external factors that affect vulnerability to the disease such
as peer use of drugs or availability of produce
20. What is the difference - communicable: spreads from one person to another but doesn't usually
between communica- result in long term health consequences
ble and noncommuni- - noncommunicable: not caused by infection and results in long term
cable diseases? consequences requiring long term treatment and care
21. why does influenza B - it is a communicable respiratory disease that has a high mortality rate
