Disease, illness and ill health are not randomly distributed in a population.
8. True or False: Epidemiology is the study of patterns of health and disease
in populations and the factors that influence these patterns. True

Unit 2
1. The following increases prevalence, except: Death
2. In a community of 1,000 people, they recorded 5 new cases of TB this
month. Over the year, there were 25 cases of and none has died or is healed.
The incidence of TB is: 5/1000
3. In a hospital, there are 9 doctors and 12 nurses. The ratio of nurses to
doctors is: 12:9
4. Circle the most appropriate explanation on “Prevalence rate”: The number
of patients who have the disease at a particular time, divided by the
population at risk of having the disease at that time.
5. In a hospital, there are 9 doctors and 12 nurses. The proportion of nurses
is: 0.57
6. Incidence rate can be expressed as: Number of new cases of disease or
injury during specified period divided by Time each person was observed,
totaled for all persons
7. A new treatment is developed that prevents death but does not produce
recovery from disease. Which of the following will occur? Prevalence will
increase
