AND ANSWERS GRADED A+ 2025/2026
What is epidemiology? - ANS The study of what is among the people
The study of determinants/ risk factors and distribution of disease in a population
Who is the father of epidemiology? - ANS John Snow, 1854
who is John Snow (1854)? - ANS The "father of epidemiology"
- he was the first one to collect data. He recorded the data of people who suffered from cholera
and dies from it (Water from Broad Street Pump got contaminated with cholera)
what is classical epidemiology? - ANS In public health.
-General population-orientated
-focuses on health problems within the community
what is clinical epidemiology? - ANS Patient-orientated
-focuses on health problems in the health care setting

origin of in bioterrorism

, what is infectious disease epi? - ANS Investigates occurrence of epidemics of communicable

*close relation to clinical epidemiology
what is chronic disease epi? - ANS study long-term effects on chronic disease risk of physical
and social exposure.
-Dependant on sampling and statistical methods. A disease that manifests itself overtime or risk
factors
*close relation to classical epidemiology
what is the term "Little Epi" - ANS Faught 1997. Randomized Blind Experimental Trial
Experimental Design - ANS always animal models (rats) and used parametric data (normal
distribution)
Randomized Control Trial - ANS Closer to experimental design
- A mix of human and animal models
- mostly parametric, sometimes non parametric data
Randomized Clinical Trial - ANS Always human models
-uses non-parametric
- categorical in nature, can't fit in a normal distribution
