A zombie outbreak refers to a fictional scenario where a large number of people become zombies, typically due to a virus or other contagion. These zombies are often depicted as reanimated corpses that crave human flesh, leading to widespread panic and chaos. The concept is popular in movies, video games, and literature, with notable examples including The Walking Dead and Night of the Living Dead. In these stories, the outbreak usually starts in a localized area and can spread rapidly, overwhelming communities and governments. Survivors often band together to find safety and resources while facing threats from both zombies and other humans. The theme explores survival, morality, and the breakdown of society during crises.
