In this paper, the authors attempt to discuss the methods by which molecular epidemiology studies pinpoint the origins and pathogenesis of infectious diseases as well as the sources, reservoirs, circulation patterns, patterns of transmission, probabilities of transmission, and orders of transmission of infectious agents. To make each study design more understandable, they include actual examples of research projects in the relevant field. Additionally, they discuss a few areas of research and parts of the study's design that require future consideration. They underline the importance of training competent molecular epidemiology specialists who can keep up with the field's rapid advancements as they offer some last remarks on the field's future directions.
