Incidence and Prevalence


Summary

In the video, the concepts of incidence and prevalence are explained. Incidence measures the number of new cases of a condition within a specified population during a certain time period, focusing on counting new cases. Prevalence, on the other hand, encompasses the total number of cases of a disease or health outcome in a specific population at a particular point in time, including both new and pre-existing cases, providing a snapshot of the burden of the condition. These measures are crucial in epidemiology for understanding the spread and impact of diseases in populations.
