Achievements in public health include improvement in what major areas, and recognition of what major health risks?
Improvements in: - infectious diseases - vaccinations - workplace safety - motor vehicle safety - safer food - coronary heart disease - mother & infant health - family planning Recognition of health risks: - lack of fluoride - tobacco hazards
26
Define epidemiology
Controlling health problems through the study of the distribution and determinants of health-related states and events in specific populations
27
Definite etiology
The study of causation - of why things occur As relates to epidemiology, the study of what causes a disease
28
What did Edward Jenner figure out?
That smallpox and cowpox are related and you can prevent smallpox using cowpox as a vaccine
29
What did John Snow figure out?
That a cholera outbreak was related to a particular water pump - removed the pump handle to prevent people from using it and getting sick
30
What are the (3) factors necessary for disease transmission?
1. Pathogen (usually microbe) 2. Susceptible, reactive host (like a human) 3. Environmental conditions bringing the pathogen to the host
31
What are the (3) types of disease transmission?
- direct - indirect - vector
32
What is direct transmission of a disease?
Disease passing from one person to another through physical contact
33
What does it mean if a person is a carrier of disease?
A carrier is a person who can infect others with a disease without exhibiting symptoms of it
34
What are the mechanisms of indirect disease transmission?
Contaminated food, water, and inanimate objects
35
What are the most common vectors of disease transmission?
- insects, especially mosquitos and flies | - arachnids, especially ticks
36
What are the (3) patterns of host-pathogen relationship?
- mutualistic - commensal - parasitic
37
What is a mutualistic host-pathogen relationship?
Symbiosis in which all involved organisms benefit
38
What is a commensal host-pathogen relationship?
Symbiosis in which none of the organisms involved obviously benefit from the relationship
39
What is a parasitic host-pathogen relationship?
Symbiosis in which only one partner benefits, at the expense of the other
40
What is a reservoir of infection?
A long term host of a pathogen, usually without injury to itself. Can be inanimate or living
41
What is a primary reservoir of infection? What are 2 examples?
An infection source with microbes that are viable and multiply - food - soil
42
What is a secondary reservoir of infection? What are 2 examples?
An infection source with viable microbes that do not multiply - air - soil
43
What are living reservoirs of infection?
- humans | - non human animals
44
What is zoonosis?
Any infectious disease that can pass from non human animals to humans - tape worm - mad cow disease
45
Risk of disease can vary with what characteristics or circumstances?
- age - gender - ethnicity - occupation - previous disease - nutrition - sources of food and water
46
What is the difference between endemic and epidemic?
Endemic diseases are constantly present in a population. Epidemics are a higher than expected incidence of a disease
47
What is a pandemic?
A global epidemic of an infectious disease that affects people or animals
48
What is an outbreak?
A localized epidemic —> no clear distinction between epidemic and outbreak
49
What is herd immunity?
When a critical portion of a population is immune to a disease (immune by any method)
50
How does herd immunity protect the herd?
It results in the inability of an infectious disease to spread, due to lack of susceptible hosts
51
What is BOD as relates to water quality?
Biochemical Oxygen Demand
52
What is eutrophication?
The aging of a body of water, as a result of high BOD
53
What are coliforms?
Microbes present in water that are: - Gram negative - lactose fermenting - gas producing - facultative
54
How many coliforms can be present in drinking water?
Zero
55
MacConkey and EMB agar are testing for the presence of what kind of colonies by looking for what product?
Coliforms, by looking for the presence of lactose Lactose (+) = dark purple colonies, or colonies with dark centers, depending on the test
56
What is the primary goal of sewage treatment?
Reducing biochemical oxygen demand
57
What happens during the primary treatment of sewage?
Physical process: removal of solid material in sedimentation tanks
58
What is the product of primary sewage treatment?
Effluent
59
What happens during the secondary treatment of sewage?
Biological process, either: - trickling filter: effluent sprayed over rocks, allowing microbes to digest organic material - activated sludge process: slime-forming bacteria added to effluent, which digest organic material and form flotsam. Water then treated with UV light
60
When does the most BOD reduction happen in sewage treatment?
Secondary treatment (95% reduction)
61
What happens in the tertiary treatment of sewage?
Addition of lime or alum to remove nitrates and phosphates. Dechlorination follows. Expensive.
62
How is milk pasteurized?
15 seconds at 72 degrees | Used to be 30 mins at 62 degrees
63
What enzyme should be destroyed in pasteurization?
Phosphatase
64
What is the goal of a harm study?
Assessing the causal relationship between an exposure and a disease
65
What is a confounder?
Anything that independently affects the relationship between an exposure and an outcome (disease)
66
What are the (6) conditions Hill outlined for determining causality?
1. Temporal relationship 2. Dose-response relationship 3. Experimental evidence 4. Strength of relationship (statistical significance) 5. Consistency 6. Plausibility
67
What kind of study is best for looking at multiple, interactive causes of harm?
Cohort study
68
What kind of study allows us to calculate a relative risk?
Cohort study
69
What is a relative risk?
The likelihood that exposure to a particular factor results in an specific outcome, compared to not being exposed. Ex: line workers are 5.7 times more likely to get carpal tunnel than those who do not do line work. Exposure = line work Relative risk = 5.7 times increased risk
70
What kind of study allows us to calculate an odds ratio?
A case control study
71
What is an odds ratio?
The likelihood that a group with a particular outcome was exposed to a certain factor (retrospective)
72
What does it mean if the relative risk or odds ratio = 1?
That exposure to the factor does not affect risk of disease
73
What does it mean if the relative risk or odds ratio is less than 1?
That exposure to the factor decreases likelihood of disease
74
What does it mean if the relative risk or odds ratio exceeds 1?
That exposure to the factor increases risk of disease
75
What are 2 “pros” of a case control study?
- speed: it’s retrospective so you can gather your data quickly - rare conditions: you can study rare conditions that may never develop if you were to do a prospective study
76
What did Ambroise Pare discover in the 1500’s?
Figured out how to cauterize wounds without boiling oil
77
What did James Lind study in the 1740’s?
