Fig. 4. Network of zoonotic agent sharing, created by connecting two zoonotic sources when they share at least one zoonotic agent.
The network is unipartite, and each node (circle) represents a zoonotic source that belongs to a source category: vertebrate host, vector, food, or environmental matrix. Node size represents the zoonotic source’s degree. The weight (width) of an edge between two zoonotic sources represents the number of zoonotic agents shared, adjusted for the scientific research effort. a Transmission-potential network among zoonotic sources. Node colours depict zoonotic source categories. Zoonotic hosts are additionally colour-coded based on taxonomic classes to offer further biological insights. b Communities of zoonotic sources based on zoonotic agent sharing as determined using the Leiden algorithm. Node colours represent the communities.
