Nicholson–Bailey model

The Nicholson–Bailey model is a mathematical model that helps us understand the spread of diseases. It's like a puzzle with different pieces that help us figure out how a disease spreads and how quickly it can move from one person to another. To help us understand the puzzle a bit better, we can think of it like a giant grid with each square representing a person. The Nicholson–Bailey model shows how an infection can move from person to person by looking at how close they are to each other, how often they come into contact, and how quickly they can pass it on. With this information, we can figure out how far and fast a disease can spread, and use it to come up with plans to help stop it.
