What are EV affecting items used in-battle?

So none of the EV reducing berries, or the wings or vitamins. Also, what specifically they do, such as double this one, reduce this one etc. Another question, but related so I put them together, does and exp share split the EVs like the exp? Thank you! Also, Ihateit when people just copy/ paste a link as their entire answer, or as an explanation.

Thanks a million! I am just starting to EV train, so I want to know as much as possible!

Also, EXP Share does not in fact divide the EVs. It just gives both Pokemon (the one battling and the one benefiting)all the EVs. Meaning if one of your Pokemon defeated a Sawsbuck (2 Attack EVs) then both the battling Pokemonandthe Pokemon benefiting from EXP share will get 2 Attack EVs.

Hope I helped!

Straight from Bulbapedia, the all knowing.

Also, a bit about Pokerus, that has been mentioned so many times:

When a Pokémon has the Pokérus, it gains double the effort values from battling (e.g., fighting a Magikarp will give two Speed EVs, rather than one). Effort points gained from vitamins and wings are not doubled. The infected Pokémon can infect other Pokémon with the virus for a period of about two days. However, the Pokérus timer can be delayed by several methods including placing the infected Pokémon in a PC Box.While it is represented similarly to status conditions, the Pokérus is not a status condition, so it cannot be healed at a Pokémon Center or with any status condition healing item.Pokérus has a 3 in 65,536 or approximately a 1 in 21,845 chance of being generated on a Pokémon, either wild or bred, effectively making this rarer than a shiny Pokémon, which have a 3 in 24,576, or around 1 in 8,192 chance to be found wild or hatched. Through battling or capturing this wild Pokémon, players could get this helpful virus onto their own Pokémon, and subsequently spread it around. Due to the overwhelmingly low chance of encountering the virus (about 1/3 of the chance to encounter a Shiny Pokémon), and the fact that most would not even recognize a Pokémon with the virus and may flee from it, many players don’t have a Pokémon with the virus.

tl;dr: Something so rare it probably doesn’t matter anyway, but keep a look out for it, and if at you have the good fortune, then make full use of it.
