A few of my Pokemon have a permanent status condition of PkRS. Ie. When..

Well you are a very lucky person pokerus duobles the stats that you get every time you level your Pokemon up. Example say your Pokemon would normally get 2 points on attack every time it level up 1 level instead of 2 you get 4 points on it. The virus is contegous so all of your Pokemon in your party will get it but it wont screw up your game

It will disappear after a while (if you walk with the infected Pokemon).
This is a good virus, because it makes your Pokemons grow faster.

It amplifies any EVs gained from battling when the Pok�mon levels up.

Your game is not messed up or anything but this is a very helpful virus in the game. This virus can improve all of your stat points when you grow levels. If your Pokemon has pokerus and it's in your party it will spread to your other pokemon. But these effects are temporary unless you put the infected Pokemon in your PC. In order to get it, you need A LOT of luck. You need to find a wild Pokemon with pokerus. You will know it has pokerus because it will be it's status condition. After you catch it, to make sure it really has pokerus go to any Pokemon center and the nurse will say that it is infected with pokerus.

PkRS is a disease, very rare, that can spread to another Pokemon, it helps raise
Your Pokemon more efficiently and faster. It should go away after 3 days, but sometimes it always stays. Infect the Pokemon in your box so you can keep it forever.

You are lucky! Pokerus is a rare disease which allows your Pokemon to grow at double the rate. This is a good thing and will make your adventure a lot easier.

Wow. You must be very lucky. PkRS means Pokerus, and Pokerus is a very, very, very good thing, not to mention a very rare thing to happen. You get Pokerus by battling other Pokemon with Pokerus, which I think is mostly bug pokemon. But, Pokerus gradually increases the stat of your Pokemon (your team, at least). For every step you take, their stat will increase one by one. Like I said, it's very good. It's no virus. Not a bad, at least. But, it does happen. It happened to me a few times, but I don't know how. To let your Pokemon keep the Pokerus stat, put them in the Computer and the Pokemon that has it will also have their stat increase. The pokerus spreads once you heal your Pokemon at a local Pokemon Center. Heal them, and find out. But, you must have the Pokemon that has the Pokerus stat in it. Otherwise, it won't spread.

How did you do that who did the Pokemon did you catch? Your so lucky

PkRS (Pokerus) is really good!!! Let's just say it helps your Pokemon level up well.

Well you are lucky!!Pokerus is a very rare virus that takes an immense amount of battling to get.it boosts your infected Pokemon stats.please be wary,it only lasts about week,so put the Pokemon in your PC,so it will spread to other pokemon.when you go to the Pokemon centre,the woman will say "it looks like your Pokemon are infected with POKERUS.not much is known about it,but Pokemon are said to grow exeptionally well."and they do!!!!
