👉 The network of infection refers to the complex web of interactions and pathways through which pathogens, such as viruses or bacteria, spread from one host to another within an ecosystem, including humans, animals, and the environment. This network encompasses various modes of transmission, such as direct contact, airborne droplets, contaminated surfaces, vectors like insects, and waterborne routes. Pathogens can exploit multiple entry points into a host's body, leading to diverse infection outcomes ranging from mild symptoms to severe diseases. The dynamics of this network are influenced by factors like host immunity, pathogen virulence, environmental conditions, and human behaviors, making it a critical area of study for understanding and controlling the spread of infectious diseases.
