The Pokérus is a useful little virus that can help you while you train your beloved Pokémon. You may or 🛡 may not have heard of it, but chances are that you haven't heard of it if you are reading this.

So 🛡 now how do I get this elusive virus? Well to tell you the truth… It's really based upon luck, like 🛡 most things. Even rarer than Shiny Pokémon, there's a 1 in 21,178.6 chance of getting it. To get the Pokérus, 🛡 your Pokémon needs to engage in a battle a wild Pokémon that holds the Pokérus. Simply battling or capturing this 🛡 Pokémon will allow for the virus to appear. Even running will work. You will be alerted if you have the 🛡 Pokérus in your party when you next visit the Pokémon Centre. The Pokémon nurse there will go through a dialogue 🛡 with you dealing with the Pokérus after you get them healed. You can catch it as well by catching the 🛡 Pokémon and placing it in your party to spread it.

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…
