Talk:Pokérus

PC

In my Pokémon Gold game, My Pokémon with PokéRus doesn't infect others stored in the PC, and doesn't even become immune unless it's in my party. For me there's only a chance that others become infected when I heal at the Pokémon Center, not automatic as the article implies. My Pokémon take about two days to heal. But before I edit the page, I wanted to ask if it is possible that PokéRus can act different for different trainers? -- Slim

That's how PokeRus should act. It spreads within the party, and a pogey in the PC will not lose PokeRus status. evkl 14:21, 6 October 2005 (CDT)

Pokemon Rocks America

I got a Ho-Oh and Lugia from Pokemon Rocks America 2005, and a Metang, but none of them have PokeRus, as it states in the article. Lukario 18:19, 28 November 2005 (CST)

Glitch?

Wait, is PokéRus a glitch? -- Ryguy 19:34, 29 July 2007 {EST}

No. PokéRus is not a glitch. Jonah 00:39, 30 July 2007 (UTC)

Telling if a wild pokemon has pokerus

i heard on a website that to get pokerus that you had to catch a pokemon with it, and to tell if it had pokerus ( while it's still in the wild) that it would have a status condition when it first appears. is this true?

No. You can't tell if a wild Pokémon has PokéRus, however, you can catch the disease from it without catching the Pokémon. TTEchidna 08:35, 3 August 2007 (UTC)

Day care?

Does the virus wear off in the day care center? I just got a Tangela, and I want to breed it but I want the virus to spread to my team too. >_>; Tina ^δ♫ 23:23, 6 January 2008 (UTC)

I think it will, but you could just spread it around before throwing it in the daycare by leaving it fifth in the party and battling random things. TTEchidna^G_SDS! 01:52, 7 January 2008 (UTC)

Oh shi-- good thing I got a good natured Tangela within the fifth egg. *runs off to Day care grabbing Tangela and sticks in party* Tina ^δ♫ 01:55, 7 January 2008 (UTC)

Hm, my Pokérus Ditto breeder is still infecting, after five days in the daycare. Has anyone's virus wore off? -- Professional Mole(Talk here) 23:25, 9 December 2008 (UTC)

Egg

Is it possible to get a pokerus from a egg. My friend told me that he had. --DarthCookieMonster 23:51, 6 January 2008 (UTC)

My sister got PokéRus from an egg.. the virus spread to the egg, though, then the egg spread it around the party. When it hatched, however, it was immune. Tina ^δ♫ 23:55, 6 January 2008 (UTC)

I mean the egg hatched from the daycare, and it had pokerus. --DarthCookieMonster 00:00, 7 January 2008 (UTC)

Eggs can get it, you likely got it on the egg soon after getting the egg from the daycare, and didn't check it until after it got the rus. TTEchidna^G_SDS! 01:54, 7 January 2008 (UTC)

Yes, Eggs can get Pokerus too:



but when it hatched, the burmy inside still had it. hfc2X 20:22, 5 August 2008 (UTC)

No middle caps

This is an excerpt from Pokémon Diamond at the Pokémon Center:
(...)
Little is known about the Pokérus except that they are microscopic life-forms that attach to Pokémon.
While infected, Pokémon are said to grow exceptionally well.
It's only two ocurrences of the word. Where did it appear with middle caps originally anyway? In some summary of the Oaknapped episode? --Johans 06:26, 12 January 2008 (UTC)

That's how everything with Poké is spelled. It's a Poké Ball, it's PokéRus. Etc. Tina ^δ♫ 06:29, 12 January 2008 (UTC)

Well, this one resulted being an exception :). I'm just trying to help by using spelling from the game. --Johans 06:35, 12 January 2008 (UTC)

You know? I believe it's because "-rus" is a suffix and not a word. You can bet /pokevirus/ would be spelt "PokéVirus" for sure, hehe. --Johans 07:04, 12 January 2008 (UTC)

Conditions for immunization?

I have the impression that the immunization of my infected party happened too early... I didn't walk too much, and closed my DS without turning it off by about 30 minutes. In Generation IV, does it depend on certain number of steps, or on real time? Remember that the DS does have a clock. Sadly I saved twice, and never noticed that my party was already immune before the second save (I managed to store only 1 infected Pokémon). --Johans 06:35, 12 January 2008 (UTC)

My experience shows a Pokémon only immunizes if it is in your party at midnight. If you leave your Pokémon in your party, instead of storing it at a box or at the daycare, turn off the game and turn it on again after midnight passes, the Pokémon will be immunized. It will also immunize if the game is on, anyway.-- Professional Mole(Talk here) 23:25, 9 December 2008 (UTC)

The article for Pokerus says "Any Pokémon on the player's party at the moment the system clock reaches midnight after a certain number of days in that position...will become immune." Does that refer to the position of the Pokémon WITHIN the player's party or the fact that the Pokémon is in the player's party?--Trashninja (talk) 08:55, 15 June 2012 (UTC)

In Pokémon FireRed

I have a Tauros in Firered, but I can't make it infect my other pokemon in the party. How is this? Hfc2x 00:25, 17 February 2008 (UTC)

Have they already had it?C Is for Cookie

nopes. I know that pokemon get a black dot when they already had it 'cause my brother has PokéRus too, so I asked him to infect my pokemon too. I traded him my tauros, so he infected it and traded it back, but I can't make my pokemon get it too. =( Hfc2x 04:57, 17 February 2008 (UTC)

Strange. My cousin traded me a Dialga with PokéRus, it infected my party and I traded it back. The Rus spread all around. I wonder...Optimatum^Talk|♊09:10 11 Mar 2008

Pokémon can't be infected in FRLG since there's no clock. It never spreads, but it never goes away either. The games are like a giant PC. TTEchidna 09:14, 11 March 2008 (UTC)

Ah...I see. -thinks about it- So an infected Pokémon traded to Red/Blue/Green/Yellow and traded back will still have the Rus? Optimatum^Talk|♊09:16 11 Mar 2008

From Gen II to Gen I, I'm not too sure. But from RSE to FRLG, it'll be made permanent for however long it's in FRLG. TTEchidna 09:32, 11 March 2008 (UTC)

In Gen II pokerus acts as any held item when traded to Gen I: it's still there, but you can't see it. When you trade back from Gen I to Gen II, the pokemon will still have its held item, shiny status and pokerus. =) hfc2X 18:39, 16 April 2008 (UTC)

what is the quickest way to spread it?

Obtained the Pokérus today

Sup guys, I obtained the Pokérus today while (I believe) wandering around the Fuego Ironworks. I was told I had them when I healed my party at a pokecenter by Nurse Joy. I currently have 4 infected right now, but I don't want to trade any of them. If anyone can tell me how to infect lots of other pokemon very fast, I'll be more than happy to trade you an infected guy (hopefully for something to make it worthwhile). I've never done wifi trading before, so I will have to learn that as well...Anyone got any advice?--Dragonite42 06:30, 10 July 2008 (UTC)

Battle. Battle, get all six infected, switch out all but one, repeat. TTEchidna 19:01, 10 July 2008 (UTC)

I obtained a Bidoof through the GTS with the Pokérus (its nickname is even Pokerus). I haven't found a use for it though, so it's just hanging out at my Ranch. ~$aturn¥oshi ^{THE VOICES} 19:22, 10 July 2008 (UTC)

Ok, hmmm, is there a place on Bulbapedia to organize trades? I've got about 20 infected so far. I don't know if pokemon stored in the computer become uninfected after 2 days though. --Dragonite42 00:07, 11 July 2008 (UTC)

I don't think that a boxed Pokémon will infect others. Also, most users will say to use the forums to organize trades. ~$aturn¥oshi ^{THE VOICES} 00:10, 11 July 2008 (UTC)

hey, Im using my wii to type this (computer's broken) so I cant really edit much on this question. I just read from the article that a pokemon will continue to gain double EVs even after being immunized. Is this true, because I havent heard about this from any other website?

Yeah, it's true ^Moldy_Orange 20:03, 12 July 2008 (UTC)

Hey!!

Pokémon Eggs can be infected in RSE too. Not only in DP! hfc2X 02:05, 6 August 2008 (UTC)

Absolutely right. should this be be stated in the article?BlueGasMask 04:43, 2 September 2008 (UTC)

After the infection

"Though the virus is gone, its positive effects will remain, most specifically the ability for that Pokémon to gain double EVs."
I've heard myself that it gains 2x EV's when it has the PokéRus sign and then 1.5x EV's when it wears off. Which one is correct? UltimateSephiroth ^{(user · talk · contrib)} 21:09, 31 October 2008 (UTC)

its always 2x EVs, the only difference when the pokemon is cured is that it cant pass the infection on. --Guardian of Earth |SGMS 2010

More Specific Info about spreading

Do we have more info on spreading? Such as odds, formulas, methods for quick spreading... we already know it will spread after battle, but the results vary much. Once I had three eggs infected with one battle, and another time it took me 5 battles to infect one pokémon of five "clean". Don't we have more info? -- Professional Mole(Talk here) 23:25, 9 December 2008 (UTC)

Immunization and Species

It seems we have a disagreement on how immunization happens. From my own experience, no Pokémon lasts more than one midnight with the Pokérus active(in Pokémon Diamond). Please provide testimonials to extend the concept. -- Professional Mole(Talk here) 16:30, 10 December 2008 (UTC)

I've gotten strains in Generation II and Generation IV last more than one midnight in the party. In fact, I've NEVER had a Pokérus in Generation II that vanished after just one midnight. The strain I got in Generation III lasted only one midnight, regardless of whether it was cured in Generation III or Generation IV. --Shiningpikablu252 16:41, 10 December 2008 (UTC)

Would you mind specifying which ones? I've infected a Treecko in one night at 11PM, and at midnight it was immune. Not to mention once I was trading with a person, was waiting for him to get online with an infected Squirtle(hatched and infected the same night) and it got immune. -- Professional Mole(Talk here) 16:51, 10 December 2008 (UTC)

Drugs...

So if a Pokémon has the Pokérus, does it affect the amount of EVs it gains when it takes drugs? For example, a Carbos usually gives 10 Speed EVs. Will this increase to 20 with the addition of Pokérus, or are the drugs not affected by it?--Ggled 11:05, 28 March 2009 (UTC)

No, the only EVs affected are the ones given by battling. Vitamins will still give 10EVs. --Raylax 18:39, 11 August 2009 (UTC)

"small life forms"

Technically it is incorrect to say that because a virus is not a life form, although it does infect living things. Just thought I'd throw that out =p. DesiAdame 05:05, 11 April 2009 (UTC)

Try emailing Nintendo. I'm sure they'll be happy to hear you out. We, unfortunately, can't do anything about that. — THE TROM — 05:14, 11 April 2009 (UTC)

I assume Pokérus is a portmanteau of Pokémon and Virus. Viruses isn't a life form. They're agents that survive off other living things.--Clarky13 05:29, 11 April 2009 (UTC)

I suppose you could be pedantic if you really wanted, but you never know, viruses in the Pokémon world may be alive... it wouldn't be the most farfetch'd thing in that game (ucwutididthar?)--Ggled

As I recall, the Pokémon Center's nurse tells about it. ◄Kevzo8► 06:50, 11 April 2009 (UTC)

Someone go get a screenshot(s) of it. The article could use it. — THE TROM — 07:04, 11 April 2009 (UTC)

Yes, the nurse does talk to you about it, but only the first time you present it to her.--Clarky13 07:19, 11 April 2009 (UTC)

Didn't Work

My brother had pokerus long ago in his party pokemon and he managed to clone his favorite pokemon, a level 100 Luxray and trade it from his Pearl to my Platinum as a gift, so I could get through the Victory Road as fast as I could because I was desperate to migrate from my Emerald, but when I got to the elite 4 and cured my pokemon in that pokemon center nurse joy told me about pokerus, that my pokemon had it now, but I though she was talking about the luxray that had had it, so I tried it again with other pokemon he gave me with pokerus and she didn't tell me a thing about it, so I thought she wasn't counfused, and that my other party pokemon had it, but they never had the Status "pokerus" and do not have the smiley face, I know how it looks, can see it in other pokemon but the pokemon of mine that should have it don't have it, how's that possible? didn't do anything!! It just wore away and left everthing the same!! They don't have it! like if they had never, even though nurse Joy told me they did. That happened long ago, so it's really gone. Do you understand what I say? LOL. I had read this article before that happened to me and it said that it goes away, and PC storage, etc, I did it all but didn't work. MY POKEMON DON'T HAVE IT EVEN AFTER NURSE JOY TOLD MY THEY DID!! YukitoOoO 17:43, 2 May 2009 (UTC)

I think that it may just not have spread from your Luxray. Every time you battle, I think that there's a chance of the other Pokémon in your party getting infected (correct me if I'm wrong here, I may be wrong on the mechanics). But the principle is, I think that the virus just didn't spread to the rest of your Pokémon. Not only that, but the nurse at the Pokémon Center will only tell you about the existence of Pokérus the first time you heal a Pokémon with it, she won't mention it again after that. Ggled 08:56, 3 May 2009 (UTC)

I don't think that only Luxray caught it because in the first place LOL I had it already before and it can't get infected again wich means other of my party pokemon had it... but somehow it cured it and and the effects didn't stay...oh well anyway thanks for helping :D, it doen't matter anymore to me because I had to restart my game so those pokemon are lost, I only brought it up because I though the article could be a lil wrong and could add somewhere that pokerus can be lost :(. Thank you YukitoOoO 18:27, 7 May 2009 (UTC)

Question

Is it possible to determine why a pokemon receives this disease?--Thomas Michael William Patrick Sales 16:52, 15 May 2009 (UTC)

Not unless you catch the one random wild Pokémon you encounter with it from the wild. TTEchidna 00:06, 16 May 2009 (UTC)

Let us suppose

we have a milotic, which is holding a power lens, and has pokerus. this milotic of ours beats a gastly, which gives 1 special attack ev. how many special attack EVs will our milotic get? Empath-Silvio 15:06, 30 July 2009 (UTC)

Gastly gives 1EV in SAtk, then Power Lens gives an extra 4EVs. Pokérus will then double the total to 10EVs. --Raylax 18:40, 11 August 2009 (UTC)

Figured out how Pokérus transfers!

So this is for Generation IV only as I haven't tested it with other gens. YES you can place an infected pokemon in the box and it WILL keep the virus. NO the virus will not transfer to other pokemon in the box (and if it does it takes well over two weeks of gameplay) YES the infected pokemon will spread the virus to others in your party, AFTER BATTLES. So in order to get the Pokérus spread you have to have an infected pokemon in your party. --Bageese 02:25, 25 August 2009 (UTC)

Pokerus on a Shiny Pokemon?

If the chance of Finding a Shiny pokemon is somewher around 1/8000 or something, and the chance of finding a Wild pokemon with Pokerus is around 3/60000, then what is the chance of Finding a Shiny Pokemon with Pokerus in the wild?Brock*PWN* 14:12, 18 February 2010 (UTC)

Around 1/160,000,00, I suppose. —darklordtrom 10:25, 19 February 2010 (UTC)

POKeRUS removed in G1?

This article states that POKeMON with POKeRUS in G2, infected or cured, would have all traces of POKeRUS removed if traded to G1. Does this mean that their stats (that were boosted by POKeRUS) stay, but if traded back to G2, they could get it again? Tharthan 19:05, 2 April 2010 (UTC)

What are the odds?

I have been playing Pokémon for about 9 years now (My first game was Silver) and never once in the entire time I have played it or Gold, Crystal, FireRed, or SoulSilver encountered a Shiny Pokémon (other than the usual suspect of the Red Gyarados) or a Pokémon with Pokérus, and yet it seems like everyone talks about getting them like its a common everyday thing to get, nor does it seem like I can ever get my Pokémon to breed at the daycare as it seems they never like each other. More often then not when I battle with friends they always seem to have the hyper powerful Pokémon that they leveled up from the breeding process with Pokérus that easily 1-shot my Pokémon of the exact same type and level with absolutley no difficulty whatsoever... Is there any way to increase my chances of getting Shiny Pokémon or one with Pokérus? Or do I have to just grind it out? - unsigned comment from HandofCreation0 (talk • contribs)

How about you read the articles? D: The chances. and all the mechanics. are right there. Right where they're supposed to be. ▫▪Ťïňắ ^♫♥ 19:05, 3 April 2010 (UTC)

1. Pokemon need to be compatible in order to breed. See Pokémon breeding.
2. Pokerus, once found, can be easily cultivated and spread. See Pokérus.
3. There are methods to improve your chances of finding shiny Pokemon. See Masuda method and Poké Radar.

Pokérus Spread and Traded Pokemon

Not too long ago, I got Pokérus in SoulSilver. This was the first time I'd ever gotten Pokérus, so naturally I took advantage of the next opportunity I got to trade some Pokérus vectors into my Diamond version. I then tried to spread Pokérus to the rest of my party from the two infected Poliwags I sent over. I battled several times--must have been around ten--with no successful spreading, which I thought was odd, since it never took more than one or two battles in SoulSilver. Somewhat annoyed, I went back to the nearest Pokémon Center to heal my party, and then got the speech from the nurse about them finding Pokérus on my Pokémon (since I hadn't yet taken the Poliwags to any Pokémon center). After that, I was able to spread Pokérus just as efficiently as I had on SoulSilver. So is it just coincidence, or will Pokérus on traded Pokémon be unable to spread until they're brought to a Pokémon Center for the first time? If it's not a coincidence, it might be worth mentioning in the article. HerbieHero 20:34, 29 April 2010 (UTC)

I get the idea, but:

So the EVs a Pokemon receives in battle are doubled, that I can understand. But does it double the total amount of EVs a Pokemon will end up with?

I guess what I'm saying is, will a Pokemon that has been infected by the Pokerus have higher stats at lv100 than a Pokemon that never caught the disease? Shady 20:48, 1 May 2010 (UTC)

Nope. It simply makes it easier/faster for a Pokemon to reach maximum EVs. 梅子^❀_✿ 20:53, 1 May 2010 (UTC)

Pokérus "Image"

The Purple Pokérus rectangle has a problem. Because of Bulbapedia having a white background, the top of the P and the bottom of the K is invisble unless the letters are highlighed. Is that OK? Should something be done to "fix" it? Valorum27 03:56, 8 May 2010 (UTC)

I'm not having problems with it. R.A. Hunter Blade 15:56, 8 May 2010 (UTC)

That's hardly productive. We should strive to improve what we have, not shrug at the prospect of improvement. Just because you can live without the changes doesn't mean they shouldn't be made. Shady 18:29, 8 May 2010 (UTC)

Um... what? I was saying that on my computer I don't see anything wrong with it, not that "Oh, yeah, we could maybe fix it, but I don't give a crap." There is 1 row of purple pixels that should probably be added to the top, since yeah, the top of the P does blend a little. There isn't anything wrong on the K that I can see, though. R.A. Hunter Blade 19:10, 8 May 2010 (UTC)

It's not Firefox that's the problem, This is what it looks like for me, I'm using Firefox running in Vista at 1366 x 768. I think it must be the combination of Firefox and OS X that is causing the problem. And yes, I'm using the latest version of firefox, I've got it updating itself automatically.

Wow. Is it even possible to fix it if it's that specific? Shady got 10,000 for winning 23:43, 8 May 2010 (UTC)

Mm... I don't think you can, since it isn't a template, but a text format. Do the letters still look odd in this: ^P_Krs And then: ^P_Krs R.A. Hunter Blade 00:01, 9 May 2010 (UTC)

(unindent) They don't look odd when you're normal using super and subscript, but when you add the background color they do. It seems to be the background color that's causing the problem. Shady got 10,000 for winning 00:26, 9 May 2010 (UTC)

Check that- I think the problem is that the font of the actual letters is white. The background color doesn't stretch vertically to fit the top of the "P" and the bottom of the "K", and since the letters are white, they can't be seen against a white background. The letters still show up on my screen if I do this: ^P_Krs They're just out of the background "box". Shady got 10,000 for winning 00:29, 9 May 2010 (UTC)

Hmm.. it looks different here on the talk page than it does on the article itself... and it looks different when the last changes are being viewed also. R.A. Hunter Blade 04:45, 9 May 2010 (UTC)

Hopefully this will remedy the problem. The page now uses the infection icon shown on the Gen IV status screen. If there are still problems, please don't hesitate to report them. Thanks, - Kogoro | Talk to me - 12:27, 9 May 2010 (UTC)

Pokérus and EVs

I know this doesn't have much to do with Pokerus really but more so the larger subject of EVs in general. But i have some questions related to ensuring that your pokemon gain as many EVs as they can in as few levels as they can.

1. Seeing as a traded pokemon gains Exp at an accelerated rate does it also gain EVs at an accelerated rate?

2. Is the surest way to gain the maximum of EVs per level and thusly gain the highest stat boosts available to battle a huge amount of low leveled pokemon that give you as low an amount of experience possible? Can you max out EVs aquired in this manner or do the amount of EVs and the amount of exp directly coorespond? Maybe making a guide on how to ensure that your pokemon gain as manyb EV's in as few levels as possible would be a great contribution to bulbapedia, I would try but am brand new to this and really am still getting to know how the site works, thanks -Drake

Seeing as you are a new contributor, you probably won't know this, but it is better to ask these questions on the [bmgf.bulbagarden.net forums] instead of a talk page. Additionally, please sign your comments with 4 tildes (~) and put new comments at the bottom of the page. Anyways, here are the answers for your questions

1. No, as EVs aren't directly tied to experience. It is more tied to the Pokémon fainted

2. I'm not sure, but I think that is the way to EV train and maximize stats.

I'm pretty sure these can be seen on the EV page, however. Turtwig's A-B-Cs (talk | contribs) 01:01, 4 June 2010 (UTC)

Pokemon with Pokerus

On my Pokemon Platinum game, I just traded with myself (with my Pokemon Diamond game) and before I traded, Dialga (and yes this is who we're talkin' 'bout) didn't have Pokerus but when I traded it in to Pokemon Platinum, I put it straight into my PC still with no Pokerus and then the next day I went on my Pokemon Platinum, there was a smiley face on Dialga and a Smiley face in Generation IV means that there was Pokerus on that Pokemon. Is that even Possible?--Lilkaykaygal 07:49, 17 August 2010 (UTC)

Well, I have heard of similar happenings, it could be a glitch. Or there might be a small chance of it spreading in the PC. If someone could read the game's coding and find out, that would be useful. Or it was just a once-in-a-lifetime thing. But still, that is interesting. Do u use action replay, cause it could be some strange occasional side effect. ----Desukaan563's userpage has a Value Formula to measure Pokémon worth (talk) 12:19, 27 November 2010 (UTC)

Pokérus doesn't spread in the PC, Desu, so there isn't a chance of that. And an AR wouldn't screw that up either, because this is game-to-game stuff. I'll dig around for an answer on the forums. R.A. Hunter Blade 16:24, 27 November 2010 (UTC)

No, I don't use Action Replay or anything. I hate how people cheat in games. I just go by gameplay. Everything was absolutely normal.--KayKay|Chat to me! 11:41, 2 January 2011 (UTC)

Chances of Encountering Pokérus?

In Generation III onwards, does Pokérus still have a 3 in 65,536 chance of being encountered on a wild/bred pokémon like in Generation II? The article states that it became easier in later generations to get Pokérus because of certain event pokémon and the GTS, but doesn't make it clear if the chance of the virus being generated was improved since its introduction. And if it has been changed, does anyone know what the rate is now? Wannabe 17:14, 3 December 2010 (UTC)

The internal battery has run dry...

Up till recently I have been exclusively a generation one Pokémon player (Red Version more specifically); but recently I was given gold, silver, crystal, and ruby versions of the game. I had begun playing one of the generation two games, played it for about an hour; saved the game and turned it off. When I returned to the game a while later I discovered the disappointing fact that the save battery was not functioning. Further investigation revealed that the other generation two games had the same problem, making me unable to return to a saved game. The Ruby version is somewhat of a different story, its internal battery as well has run dry; disabling clock based events though allowing it still to be saved. I have the capacity, through use of a game shark, to trade Pokérus infected Pokémon from the generation two games to Ruby version. Since clock based events are functionless, and immunization seems to be a clock based event, will Pokérus remain indefinitely? Will I still be able to infect other Pokémon? The advice of anyone having experience in this area would be much appreciated. - unsigned comment from Bug Maniac (talk • contribs)

You would still be able to infect other Pokémon, as that is not time based. I would think that Pokérus would not expire in a game without time-based events. However, you can just put infected Pokémon in your PC and they will never expire (as long as they are in the PC). The reason your Gen II games don't save while your Gen III games do is because Gen II saves differently to Gen III. Also, chances are that your Ruby's battery is fine, but you are affected by the Berry glitch. --SnorlaxMonster 03:53, 28 December 2010 (UTC)

Pokérus and Healing

I've heard the chances of getting the Pokérus go up if you don't heal at a Pokemon Center. Is this true? Also, would healing at one of the rest houses (such as the hiker between Mt. Coronet and Snowpoint City) count as healing at a Pokémon center?

Base stats

Does a Pokémon have to have Pokérus to in order max out base stats? RedYoshi 19:08, 18 September 2011 (UTC)

No, that could be done with EV training. Pokérus makes it quicker. --☆YoshisWorld☆ 19:44, 18 September 2011 (UTC)

2 questions

1, if you turn back the DS clock, will a cured Pokemon have Pokerus again? 2, is it definite that a Pokemon next to the Poke with Pokerus will get Pokerus after a battle? Juzey!! (Talk) 07:16, 21 September 2011 (UTC)

Contracting Pokérus

Is Pokérus only contracted after a battle if the player uses a physical type move on the enemy with Pokérus? Fundeath712 20:15, 28 January 2012 (UTC)

Never fades

Since I got a Kyogre in trade it has had Pokerus.I traded it to black and it still has it.It's been at least a year since then and it still has it.Is there an explanation for this? TheThing12 23:04, 19 February 2012 (UTC)

Have you been playing it often or keeping it in a Storage Box? If you haven't played it very often I could probably see why it still has it. If it's been in a Storage Box for awhile it keeps it the whole time since when in a Storage Box is pretty much keeps it permanently until you take it out and use it in your Party for a few days. Afterward it can't get it again. Frozen Fennec 23:10, 19 February 2012 (UTC)

Actually I use it all the time which is the strange part TheThing12 02:11, 20 February 2012 (UTC)

Are you sure that it still has Pokérus, and not just the after-effects? The double-EVs thing doesn't go away once the Pokemon is cured. Alternatively, has it ever been out of the PC at midnight? If not, that's why it hasn't gone away. Werdnae (talk) 02:59, 20 February 2012 (UTC)

Odds of Spreading Pokerus in a Party

I have been spreading pokerus in my Pokemon and writing down the results. from 20 cases (i know there are not a lot) i got a 27%, (25% or 30% rounding up) of spreading pokerus to the Pokemon to the right on the party from the infected Pokemon. And it doesn't matter if it is not the first Pokemon any infected Pokemon in the party will pass the infection to the Pokemon next to him at the same time. If i am posting something already know sorry. (I'm using Pokemon White.) Update: after a total of 30 cases the average odds are a 0.26 chance per case. 26% chance of infecting continuous Pokemon. SilverMax (talk) 01:56, 14 July 2012 (UTC)

Hmm

I traded a Manectric from the GTS, and realized that it had Pokérus. A little later, I realized that my Volcarona (caught it, then in PC) had Pokérus. I'm wondering whether somehow Manectric spread it, or Volcarona battled a Pokémon and caught it separately. Which one would it probably be? -- Pringles 04:09, 15 July 2012 (UTC)

Odd happening on Crystal

I managed something extraordinary; creating a glitched Mew on Crystal (Obtained from Blue by the Mew Glitch) after putting it in a box with a glitch pokemon (I guess this part because can't see the pokemon), then putted it into my party (it's level somehow has been set to 0, while it's name appears to be "?GREEN?GREEN?GREEN??GREEN?GREEN?GREENXDROCKKT". It freezes when checking it's stats, but somehow you can see it's moves) and gave my Mew to the day-care lady. Somehow, the day-care lady says this "Are we geniuses or what? Want to see your ?GREEN?GREEN?Y*japanesesigns*? Green?Green???Green???????E?x.??????????GR has grown a lot. By level, it's grown by 100 (only the middle of the textblock, the rest is just filled with "GREEN" and "???"). If you want your Pokémon back, it will cost $100. (Yes, seriously just only $100, like if it had negative exp as some glitch in Generation I). Oddly, when I got my Mew back, it switched to a Primeape (which I had 5th in party while Mew was 6th) with Pokérus. My explanation for this is because of that glitched Pokemon (I have to confirm that I probably cloned some unowns for whatever reason as that box seems to be glitched) and because saving a lot of times while restarting the game several times (maybe it couldn't read Mew's level once?), but I have no explanation why it has changed to a Primeape (which also somehow seems to have different attacks as my original Primeape). The explanation for the Pokérus is that the glitched Pokemon had it (I doubt my Mew suddenly appears to have it as I'm sure I would have noticed that) or the bellsprout which I've tended to use to be able to get into that box again (as catching a wild pokemon which will be send into the box seems to "fix" the problem of crashing. Somehow the boxes still have an very odd amount value (57/20), while bellsprout suddenly is lvl 57 while I catched it near Violet City).

I'm not sure if I could do the same trick over again, but I'll try.

Edit: And I've done the same trick also with Bellsprout, which appeared to have Pokérus also (so I can't tell if it this is just 1 of a million luck that I caught a wild pokemon with Pokérus or actually because of the glitched Pokémon). I also brought it to the Pokémon Center to heal, which seemed to fix the problem that I wasn't able to see it's stats and had another odd side-effect, the sprite of the trainer actually is being used while battling wild Pokémon (like if your fighting them yourself). For some side information, healing at a Pokémon Center won't cure you from Pokérus.

After receiving some experience to Bellsprout, it seems it was at lvl 0 also (not lvl 57 which it actually states), as it levels up to 1.

For some screenshot of this event, here they are (too bad I wasn't thinking about making screenshots before putting my Mew to the day-care lady). Sorry for the poor quality of the images, couldn't make any better. I know they are very large, as I don't know how to resize them on here (or just put a link only).

If it's using the trainer sprite in battle, that likely means you have some variety of ?????. If you move it to the second slot in the overworld and then switch it in during battle, it'll use the back sprite or whichever Pokemon was out before it. I can't explain much else about your story except I think GREEN was a leftover default name in the programming from Gen I. --GARY-DOS (talk) 22:44, 12 February 2014 (UTC)

Disappeared without a trace?

I got the virus yesterday on my Crystal game and spread it to my team (and a Seaking that I only have for pokedex reasons, so I can keep it around a while)and today when I turned on the game, all my Pokemon seem to have no trace of the virus whatsoever. I read on the main thing that in gen 2 you see a black dot near the HP meter but I don't see a single pixel out of place. Also, since I play my game through Stadium 2, when I first turned on my N64 today I went to the lab and they still had the flashing red dot in their summaries, but when I went and loaded up my gameboy game and checked their statuses there's no sign they ever had it.

Spreading Pokerus

Does the infected 'mon need to participate in a battle in order to spread it to the rest of your party? Whitsoxrule (talk) 02:48, 19 June 2013 (UTC)

I don't think so. In my SoulSilver version, I traded an infected Beautifly from Platinum and spread it to my entire team without making it battle once. AGGRON989 11:51, 20 June 2013 (UTC)

No, it doesn't need to participate in battle. --SnorlaxMonster 14:19, 20 June 2013 (UTC)

Telling if Pokemon has Pokerus?

I'm seeing different things looking online. Some things I'm finding say that in Gen II Pokemon games, there's no way to tell if a Pokemon in the wild has Pokerus. Other things I'm finding say that it's got a little icon on it, which is why some trainers who might not know what Pokerus is might run from an infected wild Pokemon. Which of these is true? EllieNeo (talk) 03:52, 28 June 2013 (UTC)

I'm pretty sure, that like every other generation with Pokerus, you can't tell if a Pokemon has Pokerus until you catch it. --It's Funktastic~!_{話してください} 04:41, 28 June 2013 (UTC)

So... do you have to catch a Pokemon with Pokerus to get Pokerus, or just fight it? EllieNeo (talk) 05:02, 28 June 2013 (UTC)

In Gen IV, you only have to battle it (speaking from experience). I've only ever found Pokérus myself in SS, so I don't know about other games. --SnorlaxMonster 05:50, 28 June 2013 (UTC)

Does anyone know the answer for this for Gen II? EllieNeo (talk) 01:52, 3 July 2013 (UTC)

Years ago I got Pokérus in Gold from battling (not catching) a wild Tangela outside of Mt. Silver. I knew it was something special at the time but not how it worked, so I saved and turned off the game but neglected to box my affected Persian and it cured overnight without spreading to any other party members, whoops. RacieB (talk) 02:13, 26 September 2013 (UTC)

I had the same happen in Crystal a few months ago. It was late and I wasn't paying close attention to the game at the time. I went to a Pokecenter to heal my Pokemon and was looking away and just mashing 'A' waiting for the dialog to finish when I looked down and saw some weird info before the thank you message. I looked at my party and saw my Zubat had Pokerus but I wanted to know what Nurse Joy had said. I talked to her again and it was the normal spiel. Not realizing I had only just contracted it following my previous save, I made the hair-brained decision to do a soft reset and lost it. :( --GARY-DOS (talk) 03:25, 13 February 2014 (UTC)

Preserving the Virus for Future Spreading?

My understanding is that as long as the infected pokemon is trasferred to a PC box before the game's timer hits midnight, it will keep the virus indefinitely and can continue to be withdrawn to spread to other pokemon as much as one likes and will never be 'cured' if it is returned to the PC before midnight strikes. Is this assumption correct, or does the day counter go down for every day the pokemon is out of the PC? And if so, Is each pokemon that I infect given it's own random day counter or does it take the one from the pokemon that the infection originated from? I apologize if this has been answered before, but I'm having trouble finding specific details on preserving the 'rus. Any additional info greatly appreciated. -Gunslick (talk) 19:09, 29 September 2013 (UTC)

Different stages in Gen VI

I've been spreading the 'rus to a lot of my Pokémon, but I'm really confused about one thing. The ones who have battled the most with it have a little smiley face (pink, of course) next to the pentagon on the summary, while the ones who haven't been out that much just have the pink bar saying "Pokérus" by the type. Is there much of a difference?-- Pringles 04:27, 26 November 2013 (UTC)

I would suspect it simply means they've gotten over it (so to speak) like in previous generations. Tiddlywinks (talk) 04:36, 26 November 2013 (UTC)

Yeah, this difference is explained in the article. If a Pokémon has the Pokérus for long enough, it stops being contagious but it still reaps the benefits of it; this is signified by a little smiley face. Whenever you have a Pokémon with contagious Pokérus in your party at midnight, the game takes one day off its duration, and if you have 0 days left it turns into that smiley face. --SnorlaxMonster 04:40, 26 November 2013 (UTC)

Something isn't adding up

Ok, so I am trying to HP EV Train my Rash Natured, Pokérus infected Piplup who is holding the Power Weight. I am in connection cave battling horde after horde of Whismur. I am not sure if I am misunderstanding how the calculations and what not are suppose to go...but it seems that nothing is doubling/stacking at all.

When it was level 1, it had a HP of 12, Atk 6, Def 6, Sp Atk 6, Sp Def 5 and Speed 5. After one battle it leveled up to level 7 where it's new HP was 27, its Atk 13, Def 14, Sp Atk 15, Sp Def 12 and Speed 10. Then the next battle it leveled up to level 9 and its HP was 33, Atk 15, Def 17, Sp Atk 18, Sp Def 14 and Speed 12. Then it leveled up to lv 10 and its HP raised by 4 to 37, its Atk to 16, Def 18, Sp Atk 19, Sp Def 15 and Speed 13. Maybe I don't need to list the other stats so I will just list the HP stat from here. At Lv 11 its HP was 41, 12 = 45 and currently at Lv. 13 its HP is 49.

From my understanding, its suspose to gain 5 HP Evs from all 5 defeated Whismur, doubled by the Pokérus and then 4 more added on thanks to the Power Weight. The math isn't adding up, from what it looks like, only the Power Weight is doing anything...so is it possible that as of Gen VI Pokérus and all that other stuff no longer stacks? If so then the article needs to state this as well as the EV item article and all the other articles effected. Yamitora1 (talk) 18:11, 20 January 2014 (UTC)

No, it definitely all still stacks (I've done EV-training that way plenty of times). If you defeat 5 hordes, then do Super Training to fill in the last 2 EVs, you'll find you're at 252 EVs (I usually check by trying to use a training bag on them). I think you're just not seeing the EVs show up in your stats as early as you expect to. --SnorlaxMonster 18:15, 20 January 2014 (UTC)

Eggs inheriting Pokérus + Other Possibilities of Infection

So let me get this straight... If 2 non-infected parent Pokémon (who have never been infected with Pokérus at all) breed, there's a random chance that the resultant egg/baby could emerge/hatch already infected with Pokérus out of the blue? (and I think the distinction between whether an Egg can randomly get Pokérus when you first receive it and whether a non-infected Egg can randomly hatch into a baby with Pokérus is a bit notable)

Also, I've occasionally been breeding Pokérus-infected Pokémon in Pokémon Emerald Version (either one parent is infected or both of the parents are), and I haven't observed any Pokérus-infected Eggs that were received directly from the Day-Care Man, nor have I observed a non-infected Egg hatch into a baby infected with Pokérus. I would think that if one or both of the parents is already infected, there would be a much higher chance for an Egg to pop out that is already infected with Pokérus...? (unless that "chance" is similar to the chance that a non-infected party Pokémon can contract Pokérus from an infected party Pokémon adjacent next to it - meaning that just like you may have to battle multiple times until a given Pokémon gets infected from an infected teammate, it may also take multiple tries until infected parents produce an infected Egg?) In any case, I think some of these anomalies may need more testing..

On a side-note, I'm wondering if:

• non-infected party Pokémon can get infected from infected party Pokémon during link battles or within battling facilities such as the Battle Tower
• whether wild Pokémon in the Battle Pike and Battle Pyramid can pass on Pokérus to the player's party Pokémon
• you mix records (in Generation 3) with someone whose non-Battle Tower team (for use as a Secret Base opponent) and Battle Tower team (for use as a Ruby/Sapphire/Emerald Battle Tower opponent and/or an Emerald Battle Tower's Battle Salon partner) are infected with Pokérus, are his/her transferred teams infected with Pokérus? If so, are the transferred teams capable of passing on Pokérus to the player's party Pokémon during a Secret Base battle or a Battle Tower match?

And these also may require some rigorous testing.... >.< Fenyx4 (talk) 20:17, 23 January 2014 (UTC)

Possible Inadvertent Loss of Pokérus When Saving Inside a Pokémon Center

To clarify, I added this sentence:

In Generation III, if the player deposits an infected Pokémon inside a PC, saves inside a Pokémon Center prior to midnight, shuts off the game, resumes the game after midnight, withdraws the infected Pokémon from the PC, and exits the Pokémon Center, it is possible for the infected Pokémon to be cured of Pokérus upon stepping outside of the building.

I feel that it should be added to the page, as it could catch someone unawares who thinks that the Pokérus is retained merely by depositing a Pokémon in a PC overnight. My own assumption is that when you save inside a Pokémon Center, turn off the game and let midnight pass, and subsequently resume the game after midnight, the game performs some type of "Has midnight passed yet?" check on any Pokémon you withdraw from the PC the moment you exit the building, so an infected Pokérus could mistakenly be cured just by you walking through the door. I think I tested this phenomenon with other buildings in Pokémon Emerald Version (like the Battle Pike of Hoenn), and I think it mainly happens only when the player saves in Pokémon Centers, but I can try to double-check later with other buildings. I wasn't sure whether to classify this as a glitch or something else (as it seems like the game is just doing its job), but I think it something that can affect people who aren't paying attention and happen to save after this thing occurs (Luckily, I caught this occurrence before saving. -.-"). I only know that it happens in Emerald, and I don't have a Ruby/Sapphire with a working internal clock to test this with, but it seems plausible that the same check happens in those games. Hopefully, other people can test this quirk in Generations 2, 4, 5, and 6? Fenyx4 (talk) 20:50, 23 January 2014 (UTC)

Effect in FireRed & LeafGreen

So, Pokemon in the Gen I remakes can't transfer the infection or be cured of it, but do they still gain double EVs from a battle in these games? Meaning in-game fights, not link cable ones. --GARY-DOS (talk) 03:40, 13 February 2014 (UTC)

System Clock and Pokerus?

If I change my system clock to be after midnight, is there a chance my Pokemon will be cured of Pokerus, or does the time have to happen naturally? Kozunai (talk) 20:39, 13 March 2014 (UTC)

Apparently, GYM LEADERS can give you pokerus???

So, I was playing Black 2, and went and healed at the pokemon center before battling Cheren--no pokerus. I battle Cheren. I go back to the pokemon center to heal again, after...and am promptly informed that I have pokerus?? Weirder still, I go into my party and check and the infected pokemon was one that I didn't use in the battle--Jeanne never left her pokeball--which I hadn't realized could happen (I was given to understand that your pokemon could catch pokerus from a wild pokemon if you made contact with it). Has anyone else gotten pokerus from a trainer before? - unsigned comment from Harumei (talk • contribs)

Have you caught Jeanne or used her in a wild battle in between the two Pokémon center visits? Last I've heard, it's impossible to contract Pokérus from Trainer battles of any kind, unless if there's an already infected member in your team, who can spread it to those in adjacent positions in the party after that battle. Berrenta (talk) 19:18, 12 April 2014 (UTC)

No, I hadn't; that was my point, that I beat the gym trainers, went to the pokemon center, healed--no pokerus--then went directly back to the gym to challenge Cheren; I battled Cheren and then returned to the pokemon center, without at ANY POINT between visits having battled any one or thing else, and was informed that hey, I had pokerus! I didn't think that was possible either, but it definitely happened!Harumei (talk) 22:06, 12 April 2014 (UTC)

I can more or less confirm this. In my White 2 game, for a while now, I've been doing absolutely nothing except battling on the Royal Unova. The last time I went into the Pokemon Center for a heal, everything was fine, but today when I went in again, Mr. Medal presented me with the medal for finding Pokerus.

I don't know the mechanics of Pokerus generation in past games - the beginning of the In the games section currently says it can appear on wild or bred Pokemon - but it looks like in Gen V the game just decides whether a Pokemon in your party will become infected. You could think of it like, there's a chance that someone you're battling has the virus and that it spreads to your party. Tiddlywinks (talk) 00:29, 12 July 2014 (UTC)

Friend Safari Higher Chance?

Ok, so I was in the Friend Safari just a moment ago catching Eevee. I caught 4, 2 went into my party, 2 into the box. I had no Pokémon with the condition active in my party. I went to withdraw the ones in the box to have their IVs Judged and see if their natures are the one I need, and both of the Eevee that went to the box had Pokérus.

I'm not sure if this helps, but the Pokémon I used was a Escavalier with the Swarm ability.

Is it possible that there is a higher chance of catching Pokémon with Pokérus in the friend safari, am I just lucky and got struck by lightning twice (which from my understanding are the odds of running into a Pokérus infected Pokémon) or did the Swarm ability have something to do with it?

I am trying not to speculate or anything. I'm not sure if I can recreate the conditions again, I doubt I will ever catch another wild Pokémon in or out of the Friend Safari with the Pokérus condition.

On a side note, should I experiment to see which strain the two Eevee have. Since they were caught wild with it, sent right to the box, they should have different strains of the virus right? Yamitora1 (talk) 20:23, 16 May 2014 (UTC)

heh crap, false alarm. I did have a Pokémon with the condition and mixed them up with the ones I withdrew from the PC. Sorry about that. Yamitora1 (talk) 20:28, 16 May 2014 (UTC)

Strain X=0 Pokérus?

I've brought this up on the forums previously when editing here was restricted, but there wasn't much of a response there, so I’ll bring it up here. When I was training a Joltik, I realised that it had lost its Pokerus without leaving a smiley face, twice. I did a test and I infected 3 Pokemon using my Crawdaunt (which was the Pokemon I'd used to infect Joltik both times previously). After midnight, all the Pokemon lost their Pokerus without leaving a smiley face.

Not sure if anyone has experienced this as well, and I’ll be happy to trade a Pokemon infected with the strain of Pokerus if you want to check the claim (assuming the strain stays the same with trading). Is strain X=0 Pokerus possible in X/Y? Or is it a glitch? (Just a note, this was on v 1.2 and hopefully it's the same for v 1.3) :) --Wowy_(Talk) 04:44, 4 December 2014 (UTC)

How did you get the Pokérus in the first place? It's possible someone hacked it in a previous game and just sent the Pokémon through Transporter (it might even be possible to hack into Gen VI, but I'm not sure). --SnorlaxMonster 04:54, 4 December 2014 (UTC)

I have no idea at all! My thought was that it was from Wondertrade since I recall obtaining a few infected Pokemon through that, but besides it's definitely not the one I sent through Transporter, and I don't recall obtaining Pokerus through normal trades besides Wondertrade. It could be from wild Pokemon, but I think Wondertrade is more probable, which I guess could mean that it's hacked. :P--Wowy_(Talk) 05:13, 4 December 2014 (UTC)

Odd Pokerus

I got a legit Xerneas with Pokerus on the GTS for Omega Ruby, so I infected it with my party Pokemon. However, after more than 4 days, my Pokemon in my party still have Pokerus. I think it's because I used two different Nintendos wit different times, the Pokerus just reseted and I need to wait more days. I'm not sure why the virus isn't gone yet, so if you have an answer, please help. But I was just wondering if this was good info to add.Leafeon6954 (talk) 04:54, 19 December 2015 (UTC)

Strain X=0 Pokérus?

I just want to bounce off this topic cause it's related. I'm not understanding why X=0 is any different from X=4, X=8, or X=12 as per the table under the technical information for strains. Does X do anything besides determine what the default value of Y is? Exaskryz (talk) 04:48, 23 February 2016 (UTC)

As the page says: "If both X and Y are 0, then the Pokémon has never been affected by Pokérus."

(Also, if you have a new question, please start a new section, even if another is vaguely related to your topic—and definitely if the other is more than six months old.) Tiddlywinks (talk) 21:41, 23 February 2016 (UTC)

Managed to get Pokérus after the second gym, wow

Literally don't even know how it happened. Was playing HeartGold and after the second gym I go to heal and get the notification. I had the traded Onix so maybe that was why? Still it was pretty surprising and I was shocked I even got it considering its rarity.

Pokérus from the Virtual Console

I can confirm that a Pokémon that's been infected with Pokérus on the Virtual Console versions of the Gen II games do not carry the condition when moved via Poké transporter to Sun and Moon. PDL (talk) 04:50, 22 January 2018 (UTC)

Glitch in Colosseum - Pokérus doesn't work?

I recently went to EV-train a Raikou in Colosseum. I had it infected with Pokérus and hold a Macho Brace, and I successfully battled against the necessary Pokémon in Colosseum based on these factors. Upon doing so, however, the Raikou's stats were grossly lower than what they were supposed to be, and in fact relfected having far less EVs than it was supposed to have. This incident seems to indicate that Pokérus (at minimum while holding a Macho Brace) does not work in Colosseum?

Pokerus in Gen 8

Couple of observations about Pokerus in Pkmn Shield

- Pokerus now seems to spread through the party only if an infected pokemon takes part in the battle (didn't spread at all for 15+ battles, then spread first time when the infected mon was first in party)

- Pokerus infected/cured symbols don't show in battle or on switching screen, only in summary

- Eggs don't display infected symbol, even if they are infected (egg with no infection hatched into mon with infection)

Abish (talk) 01:24, 30 April 2020 (UTC)

Odds of initial infection and the Gen V algorithm

The page states that the odds of initial infection are 3 in 65536, implicitly for all games. The algorithm for Gen V listed in the article takes a random number and keeps the bottom 14 bits (ands with 0x3FFF) and sees if that is equal to 0. This can only be the case if all 14 bits are 0, which gives odds of 1 in 2^14 (1 in 16384, 4 in 65536).

The algorithm in Gen II, on the other hand, does have odds of 3 in 65536, which is that it generates a random 16-bit number and does the initial infection if subtracting 3 from it would cause a carry, which is only the case for 0, 1, and 2. It should therefore be ascertained when this odds change occured and if it was reverted, or if the random number generation is flawed in Gen V such that it is indeed 3 in 65536. SNBeast (talk) 04:22, 19 June 2022 (UTC)

I've been told that the actual Gen V algorithm is to check if the bottom 14 bits are 0 and any of the two above them aren't. This does indeed change it to 3 in 65536, because this other check multiplies the 4 in 65536 by 3 in 4 (top bits not 00). This needs to be verified and if true the page's description of the algorithm updated. SNBeast (talk) 13:21, 19 June 2022 (UTC)
