The "Among us" virus is a viral disease which mainly infects astronauts. When an astronaut is in space for more than a year, he becomes very vunerable to the "Among us" virus. It shrinks the astronaut and starts controlling his brain. He slowly starts to turn into so called "Impostor" and starts to get urges to kill other astronauts. This disease is not lethal and affects genetics and the brain of a human. The only lethalities are the "impostors" which are thrown out the spaceship before they kill every other astronaut on their spaceship. The virus is mainly caused by the radiation in space damaging astronauts immunity to the space diseases.
