Chapter 3 Practical Disease Concepts in Epidemiology
1. Which of the following best defines disease in epidemiology?
a. A temporary dysfunction of the body's systems
b. A condition that only affects the immune system
c. An interruption, cessation, or disorder of body functions, systems, or organs
d. Any abnormality in body structure
2. Which of the following is NOT a common cause of disease?

d. Lifestyle factors like diet and smoking
3. In the field of epidemiology, what does the term "environment" encompass?
a. Only the physical surroundings of an individual
b. The presence of bacteria and viruses in a specific area
c. All external factors to the human host, including physical, biological, social, and
cultural influences
d. The genetic makeup of a population
4. Why is the study of disease causation a primary focus in epidemiology?
a. To classify diseases based on severity
