Translations:Pokérus/2/en

Description
The Pokérus is a microscopic life-form that may attach to Pokémon, which your Kanto starting Pokémon will be infected with in Sinnoh. It is a beneficial mechanic that a Pokémon can obtain. Your chosen Kanto starting Pokémon will be infected by the Pokérus after clearing Distortion World for the first time. Once a Pokémon is infected by the Pokérus, it may gain Effort Values (EVs), which increase attack from that Pokémon.
