It's called Pokerus, not poke-rush. Anyway, the way to get it is sheer luck. Random Pokemon in the wild may have Pokerus. By either defeating it or catching it, your Pokemon (unless if you caught it) will have pokerus. If you caught it, the infected Pokemon will still have it. I assume you already know what it does, and this is where I end my answer.
To catch a pokemon, you require a Poke ball, which you can buy from a poke mart.
If you use the Poke Radar you will have a chance of getting a shiny Pokemon. But the actual Pokemon will not USUALLY change by using the Poke Radar.
