I got Pokerus twice in Emerald. On the first time, it just randomly came about from the Johto starters that I traded from Colosseum, and it somehow infected every single Pokemon that I owned. The second wave came when I caught a Wild Ditto that had it, which proceeded to infect every Pokemon that I got after the first wave ended. I kept an Entei in my PC with it, but I have no idea what happened to it since then.
I've also been able to get it in Pearl, where it spread through my party quickly and went away just as fast. Didn't get to keep any Pokemon in reserve there.
I currently have it on Platinum, since I got an Armaldo off the GTS that had it. I now have a Slakoth and Skorupi reserved with it.
I'm hoping to send Skorupi to White when I get a chance, so I can have an epidemic there as well.
