Translations:Pokérus/2/en

Description
Pokérus is a microscopic life-form that can attach to Pokémon. Your Kanto Starter Pokémon will automatically be infected with Pokérus upon clearing the Distortion World Dungeon in Sinnoh for the first time. Pokérus is a beneficial virus to any Pokémon that catches it. Once a Pokémon is infected by the Pokérus, it may gain Effort Values (EVs), which multiplicatively increase the attack of that Pokémon via the EV Damage Multiplier.
