answered already passed
host
environment
agent - correct answer ✔✔three parts of the epidemiological triangle
host - correct answer ✔✔epidemiological triangle:
- age, sex, race, genetic profile, previous disease, immune status, religion, customs, occupation,
marital status, family background
environment - correct answer ✔✔epidemiological triangle:
- temp, humidity, altitude, crowding, housing, neighborhood, water, milk, food, radiation,
pollution, and noise
agent - correct answer ✔✔epidemiological triangle:
- biologic (bacteria and viruses)
-chemical (poison, alcohol, smoke)
-physical (trauma, radiation, fire)
-nutritional (lack, excess)
vector - correct answer ✔✔a nonhuman carrier of disease, such as an animal or insect
direct transmission - correct answer ✔✔transmission that occurs by immediate transfer of
infectious agents from a reservoir to a new susceptible host.
(touching, biting, kissing, sex, droplet, coughing, sneezing)
, indirect transmission - correct answer ✔✔transmission that can happen several ways, does not
go from host to host
-vehicle borne, vector borne, airborne
airborne transmission - correct answer ✔✔occurs through droplet nuclei- the small residues
that result from evaporation of fluid from droplets emitted by an infected host.
ex: sneezing and coughing
acquired immunity - correct answer ✔✔immunity that develops after exposure to a suitable
agent. (body forms immunity on it's own) or artificially with a vaccine (going to MD to get
vaccine or getting exposed and creating antibodies)
passive immunity - correct answer ✔✔refers to short term resistance that is acquired either
naturally or receiving immunoglobulins
natural immunity - correct answer ✔✔species determines, genetically determines resistance
active immunity - correct answer ✔✔a long term resistance to a specific disease causing
organism, acquired artificially or naturally
agent - correct answer ✔✔a factor that causes or contributes to a health problem or condition
- can be biologic, chemical, nutrient, physical, and psychological
portal of entry/exit - correct answer ✔✔pathway by which the pathogen enters or exits
exit - correct answer ✔✔portal of ___________: path by which a pathogen leaves its host;
usually where pathogen is localized
