It is where an idea or innovation spreads out quickly and remains strong in its central location.
Diffusion in a system can be calculated using Fick's law of diffusion, which states that the rate of diffusion is proportional to the concentration gradient. The formula for calculating diffusion is D (C2 - C1) / (X2 - X1), where D is the diffusion coefficient, C is the concentration, and X is the distance.

Diffusion is the process that spreads substances through a gas or liquid. It involves the movement of particles from an area of high concentration to an area of low concentration until they reach a state of equilibrium.
Contagious diffusion is a branch of expansion diffusion. It refers to a cultural trait spreading across a population like a disease.
contagious diffusion, relocation diffusion, expansion diffusion, stimulus diffusion, hierarchical diffusion.
An example of contagious diffusion is the spread of Islam from Mecca to all the other countries around it.
contagious diffusion is strongly associated with local distance effects, whereas hierarchical diffusion often involves the leapfrogging of innovations among widely separated places
The rapid widespread diffusion of a feature or trend throughout a population
contagious expansion diffusion
Diffusion of AIDS is an example of contagious diffusion, where the disease spreads through direct or indirect contact between individuals.
The spread of Islam from Mecca to all the other countries around it. That's an example because Contagious Diffusion is The distance-controlled spreading of an idea, innovation, or some other item through a local population by contact from person to person.
any characteristic that hasn't spread throughout a population
The three types of expansion diffusion are contagious diffusion, hierarchical diffusion, and stimulus diffusion. Contagious diffusion occurs when a trend or idea spreads rapidly through a population, much like a virus. Hierarchical diffusion involves the spread of an idea from a person or place of power to other individuals or regions, often following social or political hierarchies. Stimulus diffusion occurs when a cultural trait or idea is adopted and adapted by another culture, leading to variations of the original concept.
This type of diffusion is known as contagious diffusion. It occurs when an idea, trend, or innovation spreads rapidly and extensively through a population, often through person-to-person contact or communication channels.
They are all similar in the sense that they all relate to the spread of cultural traits like ideas, clothing, food, and language, but they all differ in respect to how the diffusion comes about. To pull from my notes, relocation diffusion is diffusion that occurs when people from any given culture migrate to a place with a different culture. Contagious diffusion is diffusion that occurs when something spreads to other places around it and affects almost everyone in its reach. Hierarchical diffusion is diffusion that occurs when people from a high class or social status begin a trend that spreads to the lower classes. Stimulus diffusion is diffusion that spreads to other cultures and adapts the diffused traits to better fit with the new culture (it is only the basic idea that spreads). If you need examples, let me know. So, TL;DR: Yes, they are similar, but they have distinct differences.
