👉 The hub-infection model describes how pathogens, such as viruses or bacteria, can spread from one host to another through a central or "hub" node in a network of hosts. This network can represent physical contacts, social interactions, or even ecological relationships. When an infected individual (the "hub") comes into contact with a susceptible host, the pathogen can easily transmit from the hub to the new host, often leading to rapid spread within a population. The hub plays a critical role in amplifying the infection, as its high connectivity increases the likelihood of transmission to multiple individuals. Understanding this model helps in predicting and controlling outbreaks by targeting key nodes in the network for intervention, such as isolating or vaccinating highly connected individuals.
