For those that already have save files
You need to speak to nurse on the left hand side of the viridian pokecentre to reset the pokerus status otherwise pokemon without pokerus won't gain exp.
For those that have the message about not being able to capture pokemon.
Speak to the nurse in the pokecentre and heal your pokemon, that resets it back to normal.
