Version control is essential in epidemiology for several reasons. First, it enhances collaboration among multidisciplinary teams. Researchers can work on different aspects of a project simultaneously without overwriting each other’s contributions. Second, it ensures reproducibility, a cornerstone of scientific research. By tracking changes, researchers can recreate the exact conditions and data analyses that led to a particular finding. Third, it provides an audit trail, which is crucial for transparency and accountability in public health interventions.
