Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to control health problems. PubMed serves as a crucial tool for epidemiologists because it provides access to a vast array of peer-reviewed literature, research articles, and systematic reviews that are essential for evidence-based practice. This enables epidemiologists to stay updated on the latest research findings, identify trends in disease patterns, and evaluate the effectiveness of intervention strategies.
