like in any game go to your Pokemon party and check their summary. and if you a symbol that is pink and says "pkrs," that means your pokemon has pokerus.
Pokerus is a virus that infects your Pokemon. It catches this virus from a wild Pokemon that also has pokerus. If you keep a Pokemon with pokerus in you party, your other party members will also get this virus. However, this is a good virus as it doubles the EVs you earn from battles. Your Pokemon will eventually lose pokerus in four days but you can preserve it by keepin it in PC and allowing your other pokemons catching it.
Pokerus is a Pokemon sickness that will give your Pokemon more power by doubling the EVs you get from battle. It also spreads to the Pokemon on either side of the infected one after battles. If you mean giving them rare candies will give them Pokerus, no, but if you're asking can you give Pokemon rare candies while they have pokerus, then yes.
There is no certain number, It's just a rare occurance.
Your Pokemon can catch PokeRus from battling a wild Pokemon which has it. There is no specific location as PokeRus is found with any Pokemon, anywhere Pokemon are found. No item will give or help your Pokemon catch the virus, just battle and hope you will get it.
It means your Pokemon has had pokerus, a very rare but beneficial disease.
