rename - Wuhan coronavirus
would this move be per policy? Thanks! Jtbobwaysf (talk) 20:38, 21 January 2020 (UTC)
 * As of January 24, 2020, the current name is "Wuhan seafood market pneumonia virus" according to this site: https://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?id=2697049
 * Hi, propose we rename this using the common name that seems to have taken in the press. WSJ, CNN, NYT all following term Wuhan coronavirus. Note Wuhan is a location in China that seems to be primarily associated with its origin.
 * https://edition.cnn.com/2020/01/21/health/wuhan-coronavirus-first-us-case-cdc-bn/index.html
 * https://www.nytimes.com/2020/01/21/health/cdc-coronavirus.html
 * https://www.wsj.com/articles/china-virus-kills-two-more-patients-as-authorities-step-up-control-measures-11579614626
 * some of this was discussed here. As I said there, "novel coronavirus" is just a placeholder name.  I agree "Wuhan coronovirus" is more descriptive.  The virus will likely not receive a formal name for a while, and then the article will need to be moved again then. --Nessie (📥) 00:12, 22 January 2020 (UTC)
 * This is a copycat discussion, we already have a official proposal. Anyways, I strongly oppose the renaming because I believe that this move will not follow the Wikipedia Policy, because in my opinion, "Wuhan coronavirus" does not follow the Article title policy rule points of both "precision" and "conciseness". This is because the Wuhan coronavirus is new and not popular yet, so it does not have a popular name yet, and can easily be confused with other viruses, so it is unspecific and can be ambiguous, not following "precision". This also means that the title does not follow "conciseness", because there can be other "Wuhan coronavirus"-es for the same reason, because the virus is new and not popular yet, so the article will need to be changed again if there is another "Wuhan coronavirus". "Wuhan coronavirus" or even "Wuhan virus" is not even a popular phrase used in casual speaking yet, so the name of the virus may changed, as quote from the CDC website of January 22nd, 2020 (Pacific Time), this is a "rapidly evolving situation" and the title may change just as quickly as it rapidly evolves. 75.52.95.136 (talk) 00:37, 24 January 2020 (UTC)
 * is there an official naming policy? Or at wikipedia do we just use what the RS are using? Jtbobwaysf (talk) 06:44, 22 January 2020 (UTC)
 * in WikiProject Viruses, we usually go by what ICTV uses. But this is not officially a species yet, so i think we go with WP:COMMONNAME. --Nessie (📥) 12:28, 22 January 2020 (UTC)
 * Yes, there is an official naming policy for article titles. The link was given at the official discussion in this talk page as of January 23, 2020, 4:13P.M. in the dialog box at the top of the discussion. It says that the discussion should talk about the points given in the Article title policy at "Wikipedia:Article titles", which are that the title has to be/have "Recognizable", "Naturalness", "Precision", "Conciseness", and "Consistency". I believe that "Wuhan coronavirus" breaks both precision and conciseness. 75.52.95.136 (talk) 00:37, 24 January 2020 (UTC)
 * seems is it going to be called Wuhan Coronavirus, and today I was seeing it called WARS (Wuhan Acute Respiratory Syndrome.) Probably we should move the article to something the press is using. Nobody is using this Novel Coronavirus. Jtbobwaysf (talk) 14:29, 22 January 2020 (UTC)
 * I suggest you start the formal process at WP:RMCM because of the related discussion and the high amount of interest in this article. Also Wuhan coronavirus exists as a redirect and we'd need some help with that part --Nessie (📥) 15:11, 22 January 2020 (UTC)
 * I dont think it shoukd be called "Wuhan coronavirus" or "Wuhan Coronavirus", as it is unprofessional and ambiguous and vague. I also don't agree with calling the virus "WARS (Wuhan Acute Respiratory Syndrome.)" because a different name could be given to the virus instead, and may make rare unnoticed symptoms that may change its nature enough to give it a new name. This is because I believe that this is, quote from the CDC website, a "rapidly evolving situation" as of January 23, 2020 (Pacific Time), and the proposals for the name may change drastically, as this is a new virus and hasn't gained a huge amount of popularity yet in common social culture.
 * Also, according to the CDC website on the new coronavirus from Wuhan, the human-to-human interactions are not clearly explained yet, so this is an unknown that I believe could greatly influence the name of the virus, because of the "Acute" part of "Wuhan Acute Respiratory Syndrome", as this may be long term, and the virus could have started way earlier and the supposed "Patient Zero" may have been late to report.
 * By the way, I also think "Snake flu" is an unprofessional, unconcise, and vague name used by news articles to grab readers to read their article and make a little money to subscribe to their news. 75.52.95.136 (talk) 00:37, 24 January 2020 (UTC)

I believe people are also starting to call it "Snake flu" — Preceding unsigned comment added by 64.27.170.66 (talk) 21:13, 23 January 2020 (UTC)

Survival time of virus outside animal or man body?
Is there any knowledge about the survival time of the virus outside of the animal or human body? It is important to know if for deciding if I can reuse my mask or I can enter a room in which an infected (or probably infected) person was.

They have deciphered the virus, so I think they are making tests of this kind because this is highly important. 09:09, 23 January 2020 (UTC)~ You are right but since it is a new virus/disease, the time might be unknown to scientists, doctors, etc. I am not so sure about this as I am not a professional. But it's only my assumption.

For SARS I just checked it was 24 hours living time outside human / animal body. 130.92.100.253 (talk) 20:04, 23 January 2020 (UTC)

Source of virus - snakes
There's some twitter traffic among virologists about the phylogeny. Probably not snakes, probably bats. May want to edit that section. JuanTamad (talk) 12:04, 23 January 2020 (UTC)


 * Yes the most reliable paper is https://www.biorxiv.org/content/10.1101/2020.01.22.914952v2.full.pdf p.10 showing that during 16 years of investigations on Sars, they found many related beta-coronavirus in bats (more precisely in Rhinolophus) that they called Sars-like coronavirus, that Wuhan-cov falls into this class, and that (only) one of them found in Rhinolophus Affinis is very close to Wuhan-cov.
 * Very close means that Affinis virus is as close to Wuhan as the human h3n2 flu of 2010 is close to the one of 2019.
 * The snake stuffs is only a guess based on Codon_usage_bias in the virus genome and I don't think it is reliable for such recent zoonoses. Reuns (talk) 23:07, 24 January 2020 (UTC)


 * Highly agree. Seems that a lot of virologists are pointing out major flaws in the paper and believe that it is highly improbable for this coronavirus to have come from a snake, especially since there are no documented coronaviruses in the same family occurring in reptiles.
 * Dialtastic (talk) 00:39, 25 January 2020 (UTC)

Treatment
Something like targeted chemo or radiotherapy could be used as treatment (I understand that this is over the top but I think that it still warrants putting some more information in the Treatment section). I read a news report on it (https://www.youtube.com/watch?v=aerq4byr7ps) and they say flu antivirals have been tested but I don't know if broad-spectrum antivirals been tested on it yet, and if not perhaps the treatment section should be updated. 2A00:23C5:E41E:1200:D17A:344D:30C7:DA34 (talk) 15:25, 24 January 2020 (UTC)
 * Cancer-treatments like chemo- and radio-therapy are wildly irrelevant. If you really read or saw that somewhere, then you may safely assume that everything else from that source is equally insane. But yes, antivirals previously effective on similar coronaviruses (SARS, MERS) are being tested. --John Maynard Friedman (talk) 12:37, 26 January 2020 (UTC)
 * Seconded - it'd be wise to avoid putting any far-flung treatment suggestions in the article. No sense inciting people to injure themselves. Ekalosak (talk) 05:16, 27 January 2020 (UTC)

Request for Update on Outbreak
The article states that the outbreak reached Texas in America, but the case has not yet been confirmed to be the Coronavirus, so I would think it would be best to change it so Texas is no longer there in the article. ItsDaBunnyYT (talk) 01:07, 25 January 2020 (UTC)

Incubation period
Can we add the information on the exact (or maybe the longest) duration of the flu incubation period? You know, the time since a person was infected by the bacteria until he/she is confirmed to have the flu and must be treated immediately at the hospital. Must be from highly reliable medical-related sources. Chongkian (talk) 09:04, 23 January 2020 (UTC)

You are right Chongkian but since it is a new virus/disease, the incubation period might be unknown to scientists, doctors, etc. I am not so sure about this as I am not a professional. But it's only my assumption. Sarthakdangol (talk) 14:57, 23 January 2020 (UTC)

Xinhua News Agency (official Chinese state-run press agency) has reported that the longest incubation period of the disease is about 14 days. It also seems to be the number quoted on Chinese Wikipedia. Xinhua also mentions that judging from the experience with SARS and MERS, the incubation period may not be contagious.

Removed 'kung flu' alternate name
"Kung Flu" as an alternate name for Novel coronavirus 2019-nCoV wasn't supported by reference [3], hasn't appeared in any coverage I've seen, and generally has the flavor of a joke, so I've preemptively removed it. If someone wants to add it back, please add a supporting citation. — Preceding unsigned comment added by 2600:1700:FE10:3BF0:0:0:0:2D (talk) 19:36, 25 January 2020 (UTC)
 * https://www.zerohedge.com/geopolitical/blain-we-know-next-nothing-about-what-kung-flu-does-next is a legitimate source with the mention of it. And regardless if it's origin was a joke or not, people know what it is and reference it by that name relatively often in serious discussion too in America. 198.90.104.65 (talk) 00:27, 28 January 2020 (UTC)
 * Seconding the above. People are consistently referring to it as the "Kung Flu" in discussions on social media, chat programs, word-of-mouth, etc. Just because it was oroginally a joke doesn't mean it's not relevant. I mean, look at the Wikipedia redirection page for Boogaloo. Monstarules (talk) 00:36, 28 January 2020 (UTC)
 * I have made a redirect, kung flu, as there are quite a few "journalists" that have used the name now. Graeme Bartlett (talk) 01:50, 28 January 2020 (UTC)
 * Good enough for now. We should petition to have it added to the page though, since many people are honestly using it now. Not sure where to add the poll. Monstarules (talk) 05:04, 28 January 2020 (UTC)

 * "Kung flu" is a joke name based on a heavy handed racial stereotype, including it as a legitimate alternative name makes wikipedia article look unprofessional and stupid. its mention in the article might have also come directly from the wikipedia article itself, which would be Circular reporting.

Infectious during incubation controversy
There is a statement in the virology section stating "The virus is infectious even during the incubation period."

While this is stated definitively in the Wikipedia article, this is not a confirmed fact, and has been disputed both by epidemiologists and US officials. (https://q13fox.com/2020/01/26/china-says-coronavirus-can-spread-before-symptoms-show-calling-into-question-us-containment-strategy/ )

I recommend that this statement be ommited until further information is discovered. — Preceding unsigned comment added by 67.200.137.27 (talk) 22:29, 27 January 2020 (UTC)
 * Sadly this controversy was caused not least by the Health Minister in China, Ma Xiaowei, see > https://www.foxnews.com/health/coronavirus-spread-during-incubation-period-chinese-official-claims
 * It will require a high level countervailing statement from top officialdom/WHO to clarify, if he is wrong. Wikimucker (talk) 08:01, 29 January 2020 (UTC)


 * From what I have understood about the comments, the CDC have only said that they don't have evidence for human-to-human transmission during the incubation period, but that doesn't mean the Chinese assertions are wrong. Sadly I don't have the source link to hand and I can't find it on Google. Tsukide (talk) 09:58, 29 January 2020 (UTC)
 * I remember the US CDC (not the Chinese one) saying that. However China clearly has more data! Wikimucker (talk) 11:39, 29 January 2020 (UTC)
 * Such as this ? Estimates based on (Chinese) CDC data: latent days 1-7, asymptomatic infectious days 8-16, symptomatic day 17+, R_0 = 4.08 +- 0.7, CFR = 6.5%. 89.206.113.120 (talk) 04:27, 1 February 2020 (UTC)

After all, what makes any of the knowledge in this article accurate to any extent at all? Scientific degrees, standing or "proper referencing", phlogiston anyone?

mouse chimeric virus
I understand the point of mentioning an ongoing concern about SARS re-emerging as some background, but is it really the best place to mention it here where we are talking about virology? There just doesn't seem to be enough justification for mentioning a particular group's particular construct over this issue (virus with altered spike protein don't get caught by antibodies and vaccines targeting the original spike protein, yeah imagine the SURPRISE!), and I wonder what the consensus is on keeping/removing it.

Thanks for all that but I would point out that a lot of outbreak news is still coming in here thick and fast and really this article should be a science/medicine one with proper citations and relatively little outbreak news to clutter it up. Wikimucker (talk) 15:34, 24 January 2020 (UTC)
 * Wikimucker, ElHef I have a background in science/medicine though I'm more familiar with cancer research than virology. I cleaned up some of the redundant, incorrect details just now and reorganized the article to model influenza. Open to feedback. Moksha88 (talk) 05:04, 25 January 2020 (UTC)
 * Also, what's your perspective on including details of the virus in this article, 2019–20 Wuhan coronavirus outbreak? I think it makes more sense to merge the virus details from that article into this one. Moksha88 (talk) 05:15, 25 January 2020 (UTC)
 * If you could please. The science in this article will be fast moving and many papers will be published as 'open source' research rather than fully and correctly peer reviewed so unlike cancer research where a paper could be 6 months old by the time peer reviewing is completed and publication is final.
 * We will likely get papers straight off the computer screeen over the next few weeks here. It will require very delicate handling in terms of assertions made, "allegations" that are not reviewed in any way, and how this fast moving science is presented properly in wiki terms. A crap paper may even contain a nugget of gold we don't know about.
 * I do not have the science to pretend to be capable of editing an article like this beyond this point. If you would allow for less rigour than in your own field, for now anyway, you could be the perfect editor this page requires now that the 'newsy' data is moved to a different article. Wikimucker (talk) 11:36, 25 January 2020 (UTC)
 * Wikimucker, I'll do my best. I'm more adept at the medical/clinical section than the virology bits as it's been at least a decade since I completed any coursework on the topic. Moksha88 (talk) 01:12, 27 January 2020 (UTC)
 * Please do not suggest that open access research (or even better, reproducible research that is based on free-licensed software) is not (in general) peer-reviewed: the phrase could be interpreted to mean that. There are some fields, such as high energy physics and cosmology/extragalactic astronomy where almost all research is both green open access and, after a delay of typically 1-12 months for the peer review process, peer-reviewed; the article remains green open access after the peer review, and increasingly often gold open access too. Of course, many open-access and closed-access articles fail peer review. Boud (talk) 15:52, 28 January 2020 (UTC)
 * OK amended in italics to " rather than fully and correctly " . Please read my originally worded comment as 'perfect is the enemy of good', in the circumstances. Thx. Wikimucker (talk) 16:00, 28 January 2020 (UTC)
 * Thanks :). This is getting off-topic, and there's no point you making further edits here, but while peer review is a procedure fundamental to science as a systematic way of seeking knowledge (and from the Wikipedia POV is the main objective criterion we can use for deciding on medical articles to use as sources), it is not at all a guarantee of good science; see Reproducibility, e.g. this Nature article. Which also gets back to the open access aspect, which is expected to constitute a key element of improved standards in reproducibility. Boud (talk) 16:18, 28 January 2020 (UTC)
 * If you read the bit at the very beginning of the section then everything I actually asked for is in place now, what with you showing up. :)
 * You could simply delete this entire section of the talk page with my blessings.
 * You may also need to trim other discussions from the period up to ~the ~24th as they are now only clutter since the Wuhan outbreak article was spun out around that day. Obviously only the newsy rather than the sciency talk. As I said to Moksha88 this article has to be carefully curated by the scientists from now on and some of that will be 'fast science' in the circumstances.

Sources for Subgenus: Sarbecovirus
Where are the sources for the classification as Sarbecovirus? this is from February 2019, this virus was not known then, and this and that neither mentioned ›Sarbecovirus‹ nor ›lineage B‹. Of course, there is good reason to think so, but without reference, it is just speculation. NCBI 2697049 classifies this virus as ›unclassified Betacoronavirus‹. – Sivizius (talk) 00:28, 29 January 2020 (UTC)
 * Sivizius, the third source you noted ("that") says "The 2019-nCoV is a β CoV of group 2B". Does "group 2B" refer to lineage B there?

 * User:Dekimasu, yes, group 2B Cov does refer to BCoV lineage B. The "group 2" part is redundant with "β CoV", by the way. PMC1797546 gives a good example for lineages C/D as group 2C/D; you might get some good hits on "SARS 2B" too. --Artoria2e5 🌉 12:51, 29 January 2020 (UTC)

Image in the taxobox
I have changed the image in the taxobox to an image of MERS Cov, as it is in the same genus as 2019 nCov and we don't have an image of 2019 nCov without copyright issues (doubtless one will eventually come out from the cdc though) no images of SARS exist on commons either that aren't under threat of immediate deletion (the image in the taxobox of the coronavirus article was pointed out to me as being taken in 1975 and therefore could not possibly be SARS, but the wording in the image description on commons is misleading). Unlike an image of an animal or a plant, I don't really think that the image in the taxobox matters all that much, as all coronaviruses look roughly the same. Any objections? Hemiauchenia (talk) 13:22, 29 January 2020 (UTC)
 * I think it is acceptable in the context (it is clearly labeled as closely related, and not as the virus itself), but it has been commented out by another editor. I would suggest reinstating it until we can find something better. Dekimasu よ! 15:26, 29 January 2020 (UTC)

 * (ec) This is actually explicitly covered at MOS:IMAGERELEVANCE. "Images should look like what they are meant to illustrate, whether or not they are provably authentic. Similarly, an image of a generic-looking cell under a light microscope might be useful on multiple articles, as long as there are no visible differences between the cell in the image and the typical appearance of the cell being illustrated" [emphasis added; true, this is from an electron microscope]. Clearly the MERS image is informative insofar as it illustrates the "corona". There is currently some edit warring over the image on the main page, but I think this makes it clear that keeping the MERS photo should be our default for now. Dekimasu よ! 15:42, 29 January 2020 (UTC)
 * My thinking was that using the image of MERS was less repetitive than using the same 1975 Coronavirus image (that I've just linked) that is used in the main article. Hemiauchenia (talk) 15:45, 29 January 2020 (UTC)
 * That was just carried over from the edit conflict, and wasn't intended to indicate preference for one image over the other. I think both are acceptable and each is better than having no image. Dekimasu よ! 15:49, 29 January 2020 (UTC)

In the case of the second addition, listed below, it was saying "Now it seems clear that [the] seafood market is not the only origin of the virus" before we had described in the rest of the reservoir section why focus was being placed on the role of the seafood market. In general we still have an issue in this article with frequent readdition or overemphasis on individual researchers and teams, which certainly have interest in making their work seem important. I'm not particularly stating that that's what's happening here, but we should make sure the emphasis continues to remain on the virus rather than on the institutions and experts who are naturally working on it.

[In virology] CHANGE: Human-to-human transmission of the virus has been confirmed. Reports have emerged that the virus is infectious even during the incubation period, although as of 27 January 2020 officials at the Centers for Disease Control and Prevention (CDC) in the United States stated they "don't have any evidence of patients being infectious prior to symptom onset."

TO: Human-to-human transmission of the virus has been confirmed. Reports have emerged that the virus is infectious even during the incubation period, with an estimated latency period of 7 days preceeding an infectious but still asymptomatic period of 9 days before becoming clinically symptomatic. Nonetheless as of 27 January 2020 officials at the Centers for Disease Control and Prevention (CDC) in the United States stated they "don't have any evidence of patients being infectious prior to symptom onset." 89.206.113.120 (talk) 03:54, 1 February 2020 (UTC) References


 * Pictogram voting question.svg Question: This looks like a useful addition if it can be verified properly, particularly because we don't require it to be the result of academic consensus (the CDC counterstatement is left in). However, the DOI direct link does not serve as a source for what is being cited here. It does not say anything about "a latency period of 7 days preceding an infections but still asymptomatic period of 9 days". It is, as its title indicates, a preprint of a study on the effective reproduction number of 2019-nCoV. Dekimasu よ! 04:45, 1 February 2020 (UTC)
 * Red information icon with gradient background.svg Not done for now: Ah, I see. No, they input possible values for L (latency) and D (the average latent infectious period), but their study does not include any data indicating that those values are anything other than hypothetical.

 * It says (64f) that they tested different duration input variables, but that the numbers coming from the CDC proved the most robust at modelling current epidmiological observations. I find it essential for the article to mention that while already being infectious way earlier, first symptoms possibly don't occur until as late as 17 or more days after infection, which happens to substantially exceed the proposed quarantine of 14 days for repatriated foreigners. But who am I to argue the Administration. 89.206.114.52 (talk) 12:44, 1 February 2020 (UTC)
 * Since you have toggled this back to unanswered, I will follow up that in my opinion a single mathematical model really isn't sufficient to argue the length of latency or when subjects begin to be infectious without direct evidence. This is all the more the case because the unpublished paper here makes other extraordinary claims, such as the basic reproductive number over 4 and the claim that the virus has a comparable fatality rate to SARS. There is a large number of unpublished papers circulating and we have to do our best to represent what seems to be the emerging consensus. I do not think the 17-day claim is in the mainstream at this time, but perhaps others may disagree. Dekimasu よ! 16:23, 1 February 2020 (UTC)

Recoveries
Out of 213 patients confirmed dead, 187 is confirmed recovered. And while lethality typically takes place earlier in the progress of a disease, these two numbers are indicative of how lethal the infection. This section is describing very much in detail all the pertinent information in this regard except for potential mortality rates:

"As of 31 January 2020 (02:30 UTC), there were 9,776 confirmed cases of infection, of which 9,658 were within mainland China.[15] Cases outside China, to date, were people who have either travelled from Wuhan, or were in direct contact with someone who travelled from the area.[16] The number of deaths was 213 as of 31 January 2020 (02:30 UTC).[15][17] Human-to-human spread was first confirmed in Guangdong, China, on 20 January 2020[18] and has subsequently been confirmed in Germany, Taiwan, Japan, the United States and the United Kingdom.[19][20]"

SOMEONE PELASE REPLACE THIS LINE:

The number of deaths was 213 as of 31 January 2020 (02:30 UTC).[15][17]

TO THIS LINE

The number of deaths was 213 while the number of recoveries was 187 as of 31 January 2020 (02:30 UTC).[15][17] — Preceding unsigned comment added by 2600:1010:B049:8066:48AE:30A9:D0D7:D404 (talk) 19:11, 31 January 2020 (UTC)


 * I believe the reason we have not added this in the article is that the number of recoveries are only among the confirmed cases. It has also been reported that there are asymptomatic cases, and there is no way to know how many people have recovered without being diagnosed. The number of deaths, on the other hand, is more certain. However, it is reasonable to have a conversation about whether the number of verified recoveries should be added. Dekimasu よ! 05:17, 1 February 2020 (UTC)


 * So perhaps we should put: "Of the confirmed cases, 213 have died and 187 have recovered as of 31 Jan 2020". But this would be opening a can of worms and would lead people to think that the death rate for the disease was over 50%.  I suspect that it isn’t as for provinces outside Hubei the death rate is 9 died and 81 recovered i.e. a 10% death rate. Cases outside Hubei are probably much better supervised as I suspect Hubei is in chaos, and the hospitals are only taking the worst of the cases.  Most of the milder cases are probably still at home and many may have recovered without being reported. This is a good summary of the problems we have working out the death rate.
