Identifying nodes involves various methods and tools:
1. Epidemiological Surveillance: Continuous monitoring of disease cases through surveillance systems helps in identifying potential nodes of transmission.
2. Network Analysis: Using mathematical and computational models, network analysis can map out relationships and interactions between nodes to highlight key players in disease spread.
3. Geospatial Analysis: Geographic Information Systems (GIS) and spatial statistics can be used to identify geographic nodes and visualize the spatial patterns of disease incidence.
