Infected or not?

The video uses a common gaming trope of checking for infection, combined with a visual element of the NPC's yellow skin and rashes, to create suspense and engagement. The quick, decisive testing process and the clear "INFECTED" verdict at the end provide a satisfying resolution.

The video shows a player in a game using a scanner to check if an NPC is infected. The player checks for bite marks, breathing, and uses a black light, ultimately determining the NPC is infected.
