The process of phylogenetic analysis typically involves several steps: 1. Sample Collection: Collecting samples from infected individuals or other sources. 2. DNA/RNA Sequencing: Extracting and sequencing the genetic material of the pathogen. 3. Sequence Alignment: Aligning the sequences to identify similarities and differences. 4. Tree Construction: Building phylogenetic trees using computational algorithms to visualize relationships. 5. Interpretation: Analyzing the tree to draw conclusions about the evolutionary history and epidemiological patterns.
