How can you tell if your pokemon has pokerus in hg?

Question

The lady told me that one of my pokwmon had it but I looked at the summarry and I could not find it

Answer 1

You can tell if your Pokemon has the Pokerus by going to its summary. Under your Pokemon's name, next to the level there will be a purple PKRS. If your pokemon is cured of the Pokerus there will be a yellow face with red accents next to your Pokemon's image.
Hope that helps!

Answer 2

If you go to the pokemon center and you have pokerus the lady will tell you.
