Pokerus: What is it?
How do you get it?

Lol, yeah that bout sums it up. i have pokerus, so tell me if you need a pokerus infection.

I have it to, and I'm pretty sure there is a guide on this very site, believe it or not.

Don't know much about it. I do know it's like a virus that makes the infected pokemon's exp go up faster. I think it can spread to your other pokemon in your party.

i have it and i dont notice any exp. gain. there is, however, a double in EVs gained from battle. someone correct me if im wrong and i just didnt notice the exp. gain.

you are correct in saying that ryder

Funny thing is, I aquired it in Sapphire, thought it was a bad thing, 6 Pokemon had it so I put them up in boxes so no more of my Pokes would get it. A year later while I was playing Diamond I found out it doubled EV exp, so I transfered a couple over from Sapphire, and now I help other trainers obtain it. Who knew?!
