Pokerus is a beneficial virus that infects Pokemons and helps with EV training. Read on to learn about the Pokerus effects, how to spread Pokerus, and if Pokerus is good or bad in Pokemon Brilliant Diamond and Shining Pearl (BDSP).

Pokerus Meaning and Effects

Doubles EV Growth Rate

A Pokemon with Pokerus has its EV growth rate doubled and can pass it onto the other 5 members of the party. Don't worry; having Pokerus (short for Pokemon Virus) is actually beneficial to your Pokemon.

Displayed on Pokemon Summary

You can tell a Pokemon is infected with Pokerus when treating your party Pokemon at a Pokemon Center. The nurse will mention if one of them is infected. Additionally, it will also be displayed in your Pokemon's Summary page if it currently has or was infected with Pokerus.

Pokerus Icon Meanings

The effects of Pokerus will last forever, even if your Pokemon has healed from the virus. "Previously Infected" simply means that the Pokemon won't be able to spread it to your other Pokemon.

Is Pokerus Good or Bad?

Good; No Negative Side Effects

Despite its name, Pokerus has no negative side effects on your Pokemon and is purely beneficial.

Benefits to EV Training

Pokerus doubles your EV gain, meaning it'll take you half the time to get to max EVs for a particular stat.

EVs are extra points added to the base value of a Pokemon's six main stats (HP, Attack, Defense, Special Attack, Special Defense, and Speed). Defeating Pokemon in battle rewards your Pokemon with EVs.

Spread Pokerus to Party Members

Once you have 1 Pokemon with Pokerus, put that Pokemon in your party with 5 other Pokemon. Engage in battles against wild Pokemon or other trainers, and over time, the other 5 Pokemon in your party will be infected with Pokerus.

Pokerus Duration

1 to 4 Days

A Pokemon with Pokerus will recover from it in 1 to 4 days in the game. However, the effect of gaining double the EVs will remain. Once your Pokemon has recovered from Pokerus, it will not be able to infect other Pokemon and will be unable to receive it again in the future.

Prolong Pokerus by Storing in Boxes

You can prevent your Pokerus-infected Pokemon from recovering from Pokerus by storing them in Pokemon Boxes or Pokemon HOME. However, note that Pokerus does not spread to other Pokemon inside Pokemon Boxes or Pokemon HOME.
