Question

Quizplus · Accepted Answer

The incidence of a disease refers to the number of new cases in a population during a specific time period. In this case, Isaac wants to know how quickly HIV/AIDS is spreading among teenagers, so he would want to look at the incidence of new cases among this age group. Prevalence refers to the total number of cases, both new and existing, in a given population at a given time. Relative risk is a measure of the likelihood of developing a disease in a particular group compared to another group. Mortality rates refer to the number of deaths due to a disease in a population during a specific time period. While mortality rates may provide some insight into the impact of HIV/AIDS on teenagers, they do not directly measure the spread of the virus.
