Final Flashcards
biological plausability
cause and effect relationship between biological agent and disease
epidemiological causation
statistical association between risk factor and disease
modes of HIV transmission
birth blood sex
foci for HIV transmission
blood/organ transfusions, IDU, occupational exposure
Occupational exposure
800k accidental needle sticks/year, 2% are HIV needles, .5% of those get infected

Risk def
actual probability of getting HIV
vulnerability
factors that reduce ability to avoid HIV
normative model of probabilistic thinking
info weighted according to statistics rules to reach conclusions
subjective models of probalisitic thinking
more realistic, don’t have all data/info/rules to make decisions with
antigen-antibody tests
detect them in blood, can find HIV 3 weeks after exposure
RNA test
detects virus directly but can find 10 days after, more expensive
Process of HIV test
risk assess+counseling, test, wait, if negative get reduction counseling, if pos. then confirm test and counseling
serodiscordant
couple with one person pos one neg
health decision model
account for experiences, knowledge, interactions, has context
health belief model
person knows they’re susceptible and has the efficacy to do something

process instead of variables: awareness, acknowledge risk to group, acknowledge risk to self, decide to act, actually do it
health behavior change
all models work together and focus on: cognitive, emotional, behavioral, interpersonal, social ecological, structural, scientific principle
HIV prevalence def
ppl living with HIV
HIV incidence def
new cases
