Document Summary

Point prevalence = # of cases at specific time / total population at that time. Period prevalence = # of cases over time / average population during that period. The number of people with aids was 1. 2 million. = 0. 0772 or 7. 72: incidence is a measure of risk and new cases of disease over time (i. e. , there are 600 new cases /100,000). Cumulative incidence = # new of cases over time / (total population # of existing cases). Incidence rate = # of people who develop disease / (# of people at risk x # of years at risk). # of people at risk x # years at risk. = 0. 03 or 3: sometimes the at-risk population is constant. It is not safe to assume the at-risk population is constant when: There is a high death rate from other causes.
