1

What is the significance of John Snow?

Father of epidemiology
Broad St. Pump

2

What is the impact of healthcare vs epidemiology?

One patient at a time vs whole populations at a time

3

Define epidemiology

A public health basic science which studies the distribution of disease and the determinants of disease and health related events

In specific populations —> to control disease/illness and promote public health = global health

4

The ultimate goal of epidemiology

Take our learnings and collaborate with other health departments to improve public health = global health

5

Can there be sub-specialties of epidemiology?

Yes, just like in healthcare
By disease
By exposure
By population
Or in combination

6

Who employs epidemiologists?

Government —-> city
Academia
Research
Industry

7

What are the six objectives/activities of epidemiology?

Surveillance
Determine extent of disease
Study natural course of disease
Find causes
Evaluate the effectiveness of preventative measures
Assist in developing policies

8

Assumptions that must be made

Disease is not random - it is explainable why someone gets a disease
Systematic investigations can find find causes and preventative factors

Making comparisons is the cornerstone of disease assessment

9

Descriptive epi

Who-where-when

Person-place-time

10

Give examples of determinants (of disease)

Rick factors and causes of disease

11

Give examples of distribution (of disease)

Frequencies/counts and patterns of disease

12

Distribution is associated with what type of epi

Descriptive epi
3 W’s

13

Determinants of disease is associated with what type of epi

Analytical epi
Why and how

14

Name the 6 core functions of epi

1. Surveillance
2. Field investigation
3. Analytic studies
4. Evaluation
5. Linkages
6. Policy development

15

Define surveillance

Monitoring the pulse of the community

16

Define field investigation

Determine sources and vehicles of disease

17

Define analytical studies

Utilize data collected to test hypotheses and make comparisons

18

Define evaluation

Determine relevance, effectiveness, efficiency and impact of preventative measures

19

Define linkages

Communicate and collaborate with other health care providers

20

What is the focus of epi on?

Populations

21

In the definition of epi, distribution refers to which of the following?

Who, where, when

22

What is the most critical element that must be identified before the who of descriptive epi can be found?

Case definition

23

What does EIS stand for?

Epidemiology intelligence surveillance

A subset of the CDC
