Pokerus, short for Pokemon Virus, is a rare microscopic life form that attaches to Pokemon and increases the amount of EVs your Pokemon gains.

Is Pokerus Bad? Not At All!

Despite the name, Pokerus has no negative effects. It is actually good to have your Pokemon infected with it because of its powerful effects.

How to Tell if Pokemon is Infected with Pokerus

At the Pokemon Center

You will be notified that a Pokemon in your party is infected with Pokerus when you have your party healed at the Pokemon Center.

In Pokemon Stats

You can also check the stats of your Pokemon; there will be a label that your Pokemon is infected by Pokerus. An icon for Pokerus will be visible on the Pokemon's 'Check summary' screen, on the Box screen, or in Pokemon HOME.

The label will remain even after your Pokemon has healed from it. The label will change slightly, from the image of a 'spreading virus' to a more inert-looking virus, to show that the virus is no longer contagious.

How to Infect Your Pokemon with Pokerus

Battle With the Infected Pokemon in Your Party

Pokerus will spread to other Pokemon in your party as long as you have the Pokerus-infected Pokemon in your party when you go to battles.

Pokerus Duration

How Long Does Pokerus Last?

Pokemon with Pokerus will heal from one to four days in the game. However, the effect of gaining double the EVs will still remain.

Once your Pokemon has been cured, it will not be able to infect other Pokemon and will be immune to Pokerus in the future.

How to Preserve Pokerus in Your Pokemon
