2

Define incidence.

The number of new health-related events in a (defined) population within a specific point of time.

3

Define cumulative incidence.

The proportion of people who develop disease from those at risk within a specific time period.

4

Define incidence rate.

A measurement of how quickly people are developing disease. The number of people per unit time.

5

Define person-time.

the product of time and the numbers of the population who were affected, for example 100 person-years is the same as 100 people followed for 1 year or 50 for 2, 200 for 1/2.

6

List some factors of disease that increase its prevalence within a population.

long duration, incidence increase, in-migration of cases or persons at risk/susceptible, out-migration of healthy people, improved diagnostics/better reporting/treatment.

7

List some factors of disease that decrease its prevalence within a population.

shorter duration, high case-fatality, decrease in incidence, in-migration of health people, out migration of cases or persons at risk/susceptible, improved cure rate.

8

Define mortality rate.

the number of deaths in a given period within the population.

9

Define survival rate.

proportion of patients still alive from diagnosis to a given period.

10

Define disability-free life expectancy.

The number of years expected to live without some degree of disability at a given age

11
