Phylodynamics

Phylodynamics is an interdisciplinary field that integrates evolutionary biology, epidemiology, and population genetics to understand how infectious diseases spread and evolve over time. It uses genetic sequence data from pathogens to reconstruct transmission pathways, estimate epidemic growth, and assess the impact of interventions such as vaccination or treatment. In public health, phylodynamics is especially valuable for tracking outbreaks of rapidly evolving pathogens, including viruses, by revealing patterns of introduction, spread, and persistence within populations. This approach helps distinguish local transmission from imported cases and supports timely outbreak response. Phylodynamic analyses inform surveillance, risk assessment, and policy decisions by linking pathogen evolution with population-level dynamics. By combining genomic data with epidemiological information, phylodynamics enhances precision in infectious disease control and strengthens preparedness for emerging and re-emerging health threats.
