Perniciem
A dangerous corruption finds its way out of a top secret labratory. When it enters its host it stays mostly hidden until purple lines start appearing all over your body. The corruption takes over you and your brian. The corruption mutates a lot more than regular infections. The host loses control and is guided to the actions that benifit the corruption. If the corruption finds any way inside the body, it will start to take affect. This includes eating infected organsims such as cows, any saliva or blood entering(Such as bites), or any uncleaned water sources like rain or straight from a lake. Once the host gets taken over by the corruption, it will start to seek out ways to infect as many people as possible. The infection is noticable but not very. For the infection to be easily noticed the corruption would have to take significant affect in its host. Such as agression or erratic and destructive behavior. This infection could destroy the world. Perfect, but do you think you could handle the challenge?
