Infectious Disease
Infectious disease explained in an easy to understand way:
Imagine you're at a party and someone starts telling a hilarious joke that everyone begins to repeat to others. Just like how this joke spreads from person to person, infectious diseases are transmitted through pathogens from an infected organism or the environment. In this analogy, the joke represents the pathogen, the guests are the organisms, and the way the joke circulates mirrors the way diseases can spread through a community.
Practice Version
