While we're waiting (and waiting) for Pokebank to be released, I realized that X/Y represents a unique chance to study how Pokerus gets transmitted and spread. As a reminder, Pokerus is a EV-doubling condition with a 1/21,845 chance of being found in an encountered Pokemon (either encountered or hatched). Pokerus is about one third as likely as encountering a shiny in the wild. With X and Y being (for the most part) isolated from previous generations, the Pokerus rate should not be affected too much by tons of people having Pokerus from Gen IV and Gen V. From personal experience, it usually took less than ten GTS trades to get a Pokemon with Pokerus, which I would then use to infect my trade fodder Pokemon, and continue the spread. In addition to the survey at the top, I'm curious about a couple of things: If you have Pokerus, do you infect Pokemon and send them out by Wonder Trade? Post them on GTS? Hold on to them? How long did it take for you to get Pokerus? If you answer "other" in the survey, please give your answer in the thread. Let's see what becomes of this.
