Infectious Disease

Real World Example

Imagine you're in a room full of people, and someone starts telling a captivating rumor. Just as that rumor spreads rapidly from person to person, an infectious disease spreads through pathogens, moving from an infected organism or the environment to another host. The rumor represents the pathogen, the people are the hosts, and the way it spreads through the room is akin to how diseases travel through populations, highlighting how both rely on transmission from a source to new recipients.
