What is the primary objective of descriptive epidemiology?

To determine the cause of a disease

To address who, what, where, when, and how much of a variable under study

The primary objective of descriptive epidemiology is to address who, what, where, when, and how much of a variable under study. This branch of epidemiology focuses on providing a detailed overview of health-related states or events in populations, describing their distribution in relation to time, place, and people. By identifying patterns and trends in data, descriptive epidemiology helps public health officials and researchers understand the context of a disease, including its prevalence and characteristics.

This information is crucial for forming hypotheses that can be tested in further analytical studies aimed at identifying causative factors or evaluating interventions. In contrast, descriptive epidemiology does not directly address causal relationships or the effectiveness of interventions; rather, it lays the groundwork for later, more complex epidemiological inquiries.
