Let's 💰 start with what it does. The Pokérus is, as mentioned before, very helpful in training your own Pokémon. If you 💰 have the Pokérus on a Pokémon, you have probably noticed that it will spread to the other Pokémon in your 💰 party and when you level one of those Pokémon up by battling, their stats will increase higher than usual. The 💰 reason for this is because the Pokérus doubles the Effort Points you've obtained. In other words, it's just like the 💰 Macho Brace you get north of Mauville except without the speed boost and it doesn't take up an item slot. 💰 (For more info on Effort Points, go take a look at the Effort Value guide.)

The duration that PokéRus lasts is 💰 dependant upon a random number, known to some as the strain of the virus and can last anywhere from 1 💰 to 4 days. This gives ample time to spread the virus to other Pokémon. When the PokéRus has gone through 💰 the specific amount of time that the strain allows it, the Pokémon will no longer be able to spread PokéRus 💰 and it will now have a face on the status screen. However, despite it not being contagious, as of Diamond, 💰 Pearl & Platinum, it will still receive the boost of Effort Values so it will forever be good. If you 💰 want to keep it being contagious, however, you can keep it in your box and remove it whenever you wish 💰 to spread it.

And that is amazingly everything related to the Pokérus…
