Disease Spread
Definition
The transmission of illnesses from one person to another or from an animal to a person. This can happen when someone comes into direct contact with an infected person, animal, or object; inhales airborne germs; or consumes contaminated food or water.
Analogy
Imagine being at a party where there's glitter everywhere (and we all know how hard it is to get rid of glitter). If one person has glitter on their hands (the disease), they can easily spread it by touching other people (direct contact), by touching objects around them (indirect contact), or even through the air if they blow on it (airborne transmission).
