Pokérus

Pokerus is an Awesome Condition that gives your Pokemon better stat gain than usual. It has the effect of a macho brace but without the drawback of the speed. The bad news is that Pokerus is harder to obtain than a Shiny Pokemon!!! When you see a wild pokemon, and it has a Pokerus condition, catch it or you may never get Pokerus in your life! Although Pokerus is so awesome, good things must come to an end. Pokerus condition will disappear in three days so transfer it to all your pokemon. To reserve pokerus, put the infected Pokemon in your PC. To transfer pokerus to another pokemon, just simply put the infected Pokemon and the Pokemon that you wanted to infect, in your party.

Remember although Pokerus sounds like a virus that you wanted to get rid of, you're totally wrong because the truth is the exact opposite.
