>>30021939It's a rare virus that makes the host gain EV stats faster, and spreads to adjacent party members (but not when deposited in the PC). It's useful to infect any Pokemon you intend to train. It's contagious for the first 24 hours, and then the Pokerus icon is replaced with a smiley face icon, at which means the Pokemon still has the benefit but is not contagious any more. The 24-hour timer is frozen while the Pokemon is deposited in the PC.
You should save a contagious carrier in the PC so you can infect more mons later, so you should deposit your owl. Or, if you want to use him, infect one or two other mons and throw them in a box.
