6th Gen Pokerus Occurances

[Acronell]

Pokerus

Unlike other status ailments, Pokérus cannot be healed at a Pokémon Center or with any status ailment healing item, and can only be obtained by the Pokémon in question once. When a Pokémon has the Pokérus, it gains double the effort values from battling (i.e., fighting a Magikarp will give two Speed EVs, rather than one). Effort points gained from vitamins and wings are not doubled. The infected Pokémon can infect other Pokémon with the virus for a period of about two days. However, the Pokérus timer can be delayed by several methods including placing the infected Pokémon in a PC Box.
Pokérus has a 3 in 65,536 chance of being generated on a Pokémon, either wild or bred. Through battling or capturing this wild Pokémon, players could get this helpful virus onto their own Pokémon, and subsequently spread it around. Due to the overwhelmingly low chance of encountering the virus (about 1/3 of the chance to encounter a Shiny Pokémon), and the fact that most would not even recognize a Pokémon with the virus and may flee from it, many players would never have a Pokémon with the virus.
In later generations, the Pokérus became more accessible, with worldwide trading facilitated by the Nintendo DS's Wi-Fi capabilities beginning Generation IV. In fact, it is common courtesy to infect Pokémon to be traded on the Global Trade Station with Pokérus within some parts of the fandom. Also, a Pokémon's chances of being infected with the virus very slightly increase when a Pokémon has been traded from another game.

Infection

When infected, a Pokémon's status screen will indicate it much as it does any other status condition (with icon being different for Generation III and IV, while Generation V has the same as Generation IV and Gen II having no icon at all). When another normal status condition, such as Sleep, affects the Pokémon, the Pokérus icon will be replaced. As long as the Pokémon is infected with Pokérus, it can spread the virus to the other Pokémon in the player's party. The infection may spread if the infected Pokémon is in the main party after a battle. An uninfected Pokémon must be next to a Pokémon infected with Pokérus in the main party for the virus to spread. If Pokémon that have already been infected and cured from Pokérus are in the main party and are on either side of a Pokémon currently with the disease, Pokérus will not spread after any amount of battles. Pokémon that are put into the PC will keep the status indefinitely. From Generation III onward, Eggs may catch Pokérus like any other Pokémon.

My own Pokemon have already been exposed to Pokerus before I even reached the first Pokecenter in Y.

Have other people been exposed to Pokerus yet?

 

[Azire]

Just like shinies I've never gotten it before short of trading.

 

[Princess Diana]

I was Wonder Traded a Pikachu with Pokerus.

 

[TwilightBlade]

I got it through a Wonder Trade. I wouldn't be surprised if a lot of people found Pokerus. I found it in Sapphire right before the E4 and in Pearl shortly after arriving in Sandgem. I'd rather take a shiny. :p

 

[abcde123456]

I got Wonder Traded a Bibarel with Pokerus and immediately spread it to my entire team and kept a few in the PC for future use. I then infect all the Pokemon I wanna Wonder Trade and send them to spread some joy :)

 

[yewjrn]

Wonder traded a chespin with pokerus. Currently trying to spread the infection to pokemons I don't use so that I can wonder trade them away to hopefully make someone's day.

 

[Kikaito plush]

I got it from fighting a pokemon outside the breeding center now passing the PKRUS to other pokemon then putting them on wonder trade to help other people get this helpful thing.

 

[Decimosoma]

Almost 65% of all my Pokémons got this virus, I never noticed it till now. I know this is a "helpful virus" and all, but I hope it doesn't turn out to be a bad thing. Even the recent shiny I caught have it.

 

[mike39201]

I got it from an egg and it spread to about 7 pokemon.

 

[ImMe]

I caught a pokemon with Pokerus and that thing spread like wildfire.
So much that I CANNOT tell which was the first one...
