Vector

Real World Example

Imagine you're at a busy airport, and you're trying to find your gate amidst the chaos, but someone keeps handing you unwanted flyers as you navigate through the crowd. This situation is similar to the concept of a biological vector, where the organism (like a mosquito) acts like the person handing out flyers, transferring pathogens (the flyers) from one organism (the travelers) to another. Just as the flyer distributor passes unwanted papers to people moving through the airport, a vector transfers pathogens between hosts, facilitating the spread of disease.
