I got a shiny Venasaur from GTS Black/White and Nurse Joy said it had Pokerus. I opened its summary with joy only to see a small purple face just above the item. Does this mean it has recovered? It has nothing unusual in its status. I have heard that pokerus cannot go away if your Pokemon is inside a box storage, so until I get info I am leaving it there just to be safe. Please help me. I really want to infect some pokemon but if I cant, I would like to know.
Yep. It recovered. Simple as that.
(Thanks DT) It will still get full benefit, but cannot spread or recieve it anymore.
