Overview of Epidemiology quiz 1

What is the purpose of calculating disease prevalence and incidence?

• To inform public health policies and interventions

• To identify individuals at risk of developing a disease

• To track disease trends over time

• All of the above

Which of the following is an example of incidence rate?

• The number of new cases of lung cancer diagnosed in a population over a year

• The total number of cases of lung cancer in a population at a given time

• The proportion of the population that has ever been diagnosed with lung cancer

• The number of deaths from lung cancer in a population over a year

What is the difference between prevalence and incidence?

• Prevalence is the total number of cases in a population at a given time, while incidence is the number of new cases that occur over a period of time

• Prevalence is the number of new cases that occur over a period of time, while incidence is the total number of cases in a population at a given time

• Prevalence and incidence are interchangeable terms for the same concept d) Prevalence is used to measure the severity of a disease, while incidence is used to measure its spread

• All of the above

• Applied to samples of selected groups

• offered to selected groups or individuals

• offered to individuals at practice

• identification criteria are related to the need for follow up

How can public health interventions impact disease prevalence?

• Effective public health interventions can reduce disease prevalence in a population

• Public health interventions have no impact on disease prevalence

• Public health interventions can only impact disease incidence, not prevalence

• Public health interventions can increase disease prevalence in a population.

How can immunization rates impact disease prevalence?

• Low rates of immunization can increase the prevalence of infectious diseases in a population

• High rates of immunization can increase the prevalence of infectious diseases in a population

• Immunization rates have no impact on disease prevalence
