Vitamin D wording
While the NIH cite did rate the quality of all studies as 'Very low', i.e., "Any estimate of effect is very uncertain", the phrasing there is limited evidence strikes me as too dismissive and that a more appropriate characterization would be some evidence. Of the 6 studies cited re Association between vitamin D status and COVID-19 cases, the first 5 were presented with caveats; but the 6th, Merzon 2020 was presented without caveats:

Of the 7 studies cited re Association between vitamin D status and COVID-19 severity, Humanengr (talk) 05:05, 9 April 2021 (UTC)


 * In medical context, limited isn't used as a dismissive term. It is meant to be objective i.e. simply not enough in this case. The review grades each article using the NICE guidelines and has rated the evidence quality (table is from the review article) of each of the articles as "Very Low".  MartinezMD (talk) 05:52, 9 April 2021 (UTC)
 * Agree. "Limited" (or "weak") is fine. Given the wording in the source I think "limited" may be overstating it. I'd prefer "It is unclear whether ..." or "There is no good evidence that ..." given the strong caveating in the source. Alexbrn (talk) 06:16, 9 April 2021 (UTC)
 * While I'll leave it up to the others on the specific wording, I do think it's worth pointing out that WP:MEDRS says that we should only take what these national health organizations say, rather than running our own interpretation of the primary studies they based their recommendations on. It doesn't, it doesn't really matter what Merzon 2020 says, only what the NIH interprets the body of evidence to say. Bakkster Man (talk) 13:54, 9 April 2021 (UTC)
 * Agree. "Cite reviews, don't write them." -- &#123;{u&#124; Gtoffoletto  &#125;}  talk 14:19, 9 April 2021 (UTC)

The footnote from the NHS at the end of the article para says There have been some reports about vitamin D reducing the risk of coronavirus (COVID-19). My suggestion comports with that.

[Adding:] Re other suggestions above and in prior discussions  (here and here), the NIH did not say the evidence was limited, weak, unclear or that there is no good evidence. That there is some evidence (per NHS) is the primary point and should be in the body text rather than a footnote.

Rewriting the § in view of this — using the same sources (with some reordering and paring):

Humanengr (talk) 13:06, 10 April 2021 (UTC)


 * From the NHS source "There have been some reports about vitamin D reducing the risk of coronavirus (COVID-19). But there is currently not enough evidence to support taking vitamin D to prevent or treat coronavirus." Not conveying some summary of the key message here (bolded) would be cherry picking. Alexbrn (talk) 02:55, 11 April 2021 (UTC)
 * No problem … so let's start with In October 2020, the UK National Health Service noted that "There have been some reports vitamin D reduces the risk of coronavirus (COVID-19). But there is currently not enough evidence to support taking vitamin D to prevent or treat coronavirus" along with the following recommendation: …. With that I'd also remove the 'however' from the NIH sentence. Humanengr (talk) 03:02, 11 April 2021 (UTC)
 * The "along with" makes it sound like this is further comment from the NHS on COVID-19, when it isn't. So we would have a WP:SYNTHESIS problem. All we know from the NHS source about COVID-19 (the subject of this article) is that there's no good evidence of any benefit from vitamin D. Alexbrn (talk) 03:07, 11 April 2021 (UTC)
 * They didn't say there's no good evidence of any benefit from vitamin D. To avoid misrepresentation, we should begin with what they said verbatim:
 * To which we could add "The NIH said, regarding the association between vitamin D status and COVID-19 cases or severity, that "any estimate of effect is very uncertain". Humanengr (talk) 03:37, 11 April 2021 (UTC)
 * We are meant to summarize sources in our own words; quoting verbatim is a failure to do that. I'd be fine with any summary that sufficiently conveys the lack of evidence the NHS emphasizes. As to your current recommendation, putting the NHS's general recommendation in a COVID-19 article implies it's what they're saying about Vitamin D and COVID-19; it isn't. Also "noted" is a problem word. Alexbrn (talk) 03:53, 11 April 2021 (UTC)
 * The NHS did not say there is a lack of evidence; that misrepresents what the NHS said. To address your point re 'noted', we could start with In October 2020, the UK National Health Service, in a 'Coronavirus update', stated: …. Re quoting, per WP:QUOTE, quoting a brief excerpt from an original source can sometimes explain things better and less controversially than trying to explain them in one's own words.. That's the best guidance we have for this; else we end up with one of us putting words in the mouth of the agencies. Humanengr (talk) 04:45, 11 April 2021 (UTC)
 * You think "lack of evidence" is different in meaning from "not enough evidence"!? WP:QUOTE is an essay with no policy weight. But to quote core policy (WP:V): "Summarize source material in your own words as much as possible; when quoting or closely paraphrasing a source use an inline citation, and in-text attribution where appropriate" [my emphasis]. It should be possible to summarize "there is currently not enough evidence to support taking vitamin D to prevent or treat coronavirus"; let's see. I'd be happy with "There is insufficient evidence to verify reports that vitamin D is of benefit in preventing of treating coronavirus", and leave it at that.

Agreed there is currently not enough evidence to support taking vitamin D to prevent or treat coronavirus. But that does not mean there is a lack of evidence re vitamin D reducing the risk of coronavirus (COVID-19). The referents in those two sentences (reducing the risk of coronavirus (COVID-19) and preventing or treating coronavirus) are not coextensive. The former can include reducing the severity of symptoms.

I'm ok with your "there is currently not enough evidence to support taking vitamin D to prevent or treat coronavirus" as long as we preface that with the sense of NHS's first sentence, that "there are some reports about Vitamin D reducing the risk of coronavirus (COVID-19)". Humanengr (talk) 06:08, 11 April 2021 (UTC)


 * Those were not my suggested words. I proposed "There is insufficient evidence to verify reports that vitamin D is of benefit in preventing or treating coronavirus". I'd be fine prefacing this with an "". This summarizes the source. Let's see what others say. Alexbrn (talk) 06:15, 11 April 2021 (UTC)
 * Apologies for the mis-copy; I'm ok with that text. But that --does not-- summarize the source. It plainly omits the sense of the first sentence. Humanengr (talk) 06:27, 11 April 2021 (UTC)
 * There is no "sense" other than reports exist. This is followed by an explanation of the lack of evidence. "Reports" in medical terms are worth next-to-squat. Alexbrn (talk) 06:33, 11 April 2021 (UTC)
 * Can you explain on what basis NHS included the following two sentences under the heading of 'Coronavirus update'?
 * Humanengr (talk) 06:50, 11 April 2021 (UTC)
 * Because being indoors a lot can lead to deficiency. That has nothing to do with preventing or treating COVID-19, which is the topic of this article. Alexbrn (talk) 07:04, 11 April 2021 (UTC)
 * Does 'preventing or treating coronavirus' cover all aspects of 'reducing risk from coronavirus'? In particular, does it cover reducing severity of symptoms? Humanengr (talk) 07:33, 11 April 2021 (UTC)
 * That's a general question, but if something was shown to "reduce severity of symptoms" sources would surely classify that as a treatment benefit. Alexbrn (talk) 07:52, 11 April 2021 (UTC)
 * It's not a treatment; it's a daily dosage regimen that reduces symptoms if one should subsequently be infected. It would be presented as a 'treatment' only if given after infection. (From what I have read, a bolus after infection has not been shown to be effective.) Neither is it a 'preventative'; it reduces severity of symptoms but not the binary risk of infection. In sum, it's not covered under either 'prevention' or 'treatment'. Humanengr (talk) 08:02, 11 April 2021 (UTC)
 * "a daily dosage regimen that reduces symptoms" &larr; Source? Alexbrn (talk) 08:18, 11 April 2021 (UTC)
 * Make that a daily dosage regimen has been reported to reduce severity. Several of the 7 studies reviewed by NIH in the 'Association between vitamin D status and COVID-19 severity' § — reported — albeit, with NIH's Very low ranking, i.e., where the estimate of effect is very uncertain — that supplementation prior to diagnosis reduces severity. Humanengr (talk) 08:53, 11 April 2021 (UTC)
 * By "several" you mean three; four did not. So, "mixed results". And the investigations are assessed not in the context of "dosing regimens" but "vitamin D status" - which is something more applicable to certain populations. Somebody exposed to a lot of sunlight will not be deficient. We already say "there is limited evidence that vitamin D deficiency increases the risk of severe COVID-19 symptoms", which seems fair. Alexbrn (talk) 09:05, 11 April 2021 (UTC)

Re ‘limited’ vs ‘some’: from the NIH 1st para — “Some studies found a negative association between vitamin D status and COVID-19 incidence.” Humanengr (talk) 09:30, 11 April 2021 (UTC)
 * So now we're on to incidence? We know from the NHS source there is insufficient evidence about that. I think at this point if you have a precise proposal, please spell it out. Alexbrn (talk) 09:37, 11 April 2021 (UTC)
 * Apologies for that misdirection and thx for prompt to reread more closely. (We all — NIH included — make mistakes: their Table 6 lists six studies re association of vitamin D and cases, but their 'cases' text doesn't cover Hernandez 2020; their intro para under 'severity' states there are seven studies, but their text and Table 7 address eight.)
 * Two studies (Annweiler 2020 and Annweiler 2020a) addressed supplementation and found it negatively associated with both severe COVID-19 and death. Yes, the estimate of effect is very uncertain, but no studies contradicted those findings. The NIH lead sentence in the 3rd para under 'severity' Results associating vitamin D status with COVID-19 severity scores were mixed is misleading as the only negative was Annweiler 2020 reporting there was no difference when only receiving a bolus when diagnosed.
 * Propose adding: Supplementation with vitamin D has been found to be negatively associated with both severe COVID-19 and death, although the estimate of effect is "very uncertain".[NIH]. Or more readably: Vitamin D supplementation has been associated with a reduction in the severity of symptoms and death from COVID-19, although the estimate of effect is "very uncertain".[NIH].
 * The details re Annweiler (with some reordering for readability): Supplementation for a year was significantly negatively associated with having severe COVID-19 [Annweiler 2020a]; Supplementation before diagnosis (Annweiler 2020); within a month before, up to a week after diagnosis, or for a year before diagnosis [Annweiler 2020a] were negatively associated with death post COVID-19 diagnosis. Humanengr (talk) 21:41, 11 April 2021 (UTC)
 * I have significant concerns with the phrasing, especially for the NHS info, as it appears to have been flipped on its meaning. They're primarily referencing Vitamin D deficiency, with possibilities of deficiency causing increased COVID risk and social distancing resulting in more people being deficient. The above phrasing gives an (unintended) emphasis on use of Vitamin D (whether deficient or not) to reduce risk, rather than the consensus view which appears to be that Vit D deficiency increases risk. Even the verbatim quoting has this issue, because the page is written on the overall Vitamin D recommendations, and quoting this COVID disclaimer here could end up giving WP:UNDUE weight since this isn't an article about Vitamin D. Put more simply, You should take 10 micrograms (400 IU) of vitamin D a day between October and early March to keep your bones and muscles healthy in this context could imply that the Vitamin D is recommended for COVID specifically, rather than general health. Bakkster Man (talk) 01:21, 12 April 2021 (UTC)
 * I agree with that analysis of the dangers, but think the wording as of now is okay. Alexbrn (talk) 05:16, 12 April 2021 (UTC)
 * Are you referring to the current wording on the article page (citing only the systemic review directly, rather than NHS/NIH) or the proposed update above? Bakkster Man (talk) 15:18, 12 April 2021 (UTC)
 * this version. But I added the recent review since then (also fine IMO). Alexbrn (talk) 15:32, 12 April 2021 (UTC)
 * As a heads up, the article currently has a very different wording, with no mention of Vitamin D deficiency at all. Bakkster Man (talk) 18:10, 12 April 2021 (UTC)
 * I don't think those proposals are very neutral as they give undue weight to the poor underlying research rather than reflecting the principal knowledge in the secondary source (i.e. that there is no good evidence of benefit). Alexbrn (talk) 05:20, 12 April 2021 (UTC)
 * The proposals characterize the secondary source using the wording of the NIH. Where do you see the underlying research characterized as 'poor' or that the principal knowledge in the secondary sources shows "there is no good evidence of benefit"? Humanengr (talk) 05:43, 12 April 2021 (UTC)
 * In Wikipedia terms such studies are "poor" because they do not convey the accepted knowledge we are meant to reflect (hence, they fail WP:MEDRS). We should reflect the analysis and synthesis of the secondary source rather than majoring on the primary source's details and then squirreling the knowledge away at the end of the sentence in scare quotes, as you have done with "very uncertain". Bringing your own analysis to the table (the nonsensical "no studies contradicted those findings") is bad, and bespeaks of a POV. The summary of this source is "no good evidence". In lieu of newer sources I suggest we're done here. Alexbrn (talk) 06:03, 12 April 2021 (UTC)


 * What if the summary is longer than the summarized? Or, to summarize, your version uses more and different words than the original. Shtove (talk) 15:37, 12 April 2021 (UTC)
 * WP:AGF. I was taking the NIH as presenting accepted knowledge. Hence, not "poor". No studies contradicting that finding were presented by NIH. Re the scare quotes, I had forgotten WP-en uses the American convention; and am fine with reversing the order: Although the estimate of effect is very uncertain, vitamin D supplementation has been associated with a reduction in the severity of symptoms and death from COVID-19.[NIH] Humanengr (talk) 16:43, 12 April 2021 (UTC)
 * I am struggling with the concept of "studies contradicting that finding". It makes little-to-no sense in the context of evidence-based medicine where this is either evidence, or not (generally not "contradictory" evidence). Are you invoking the idea that Vitamin D is maybe harmful? Where is this concept coming from? In any case, we have an updated source now. Alexbrn (talk) 16:51, 12 April 2021 (UTC)
 * Did the NIH present anything contradicting what they presented from Annweiler: vitamin D supplementation [prior to diagnosis] has been associated with a reduction in the severity of symptoms and death from COVID-19? Humanengr (talk) 16:59, 12 April 2021 (UTC)
 * Sound like an weird original research question. What does a "contradiction" of "very uncertain" even mean? If you mean "very certain", then no they did not. Alexbrn (talk) 17:04, 12 April 2021 (UTC)
 * You're still don't grokking the basic point. The "very uncertain" refers to the amount of reduction, not the fact of reduction. Nothing 'original research question' about it. Humanengr (talk) 17:18, 12 April 2021 (UTC)
 * You're inventing meaningless things that bear no relation to sourced text, so I'm going to disengage. If new sources/proposals come to light there may be some point to this. Alexbrn (talk) 17:23, 12 April 2021 (UTC)

Lab Leak Again
See Reliable sources/Noticeboard --Guy Macon (talk) 12:50, 24 May 2021 (UTC) Guy Macon is spot on, this is what I'm referring to. There is growing consensus regarding that COVID-19 came from a lab, but yet it's still not in the article. Is this Wokepedia?

Censorship based on WP:IDONTLIKEIT
As has been widely reported in recent days, the hypothesis that Covid-19 might have escaped from a laboratory has been given increased credibility. We should not claim it to be a fact, but nor should we censor it when reliable sources reported it. Unfortunately, some users are now doing the latter - repeatedly deleting any reference to the hypothesis without any valid explanation beyond WP:IDONTLIKEIT. One user even deleted it with the edit summary "crappy sourcing", which looks rather silly when the source is Science, one of the world's most respected scientific journals. Jeppiz (talk) 09:32, 24 May 2021 (UTC)
 * So far as I can see, nobody has cited WP:IDONTLIKEIT other than you. That source has been discussed extensively at Talk:COVID-19 misinformation. See WP:NOLABLEAK for a handy overview of what the best sources are saying. Alexbrn (talk) 09:50, 24 May 2021 (UTC)
 * Sure, and I have strongly defended the ideas behind WP:NOLABLEAK in multiple discussions in the past year. However, the situation has changed as many experts no longer exclude it (as multiple reliable sources show). Science is not static and as it evolves, so should articles reflecting it. When NOLABLEAK was written, it very accurately reflected consensus among experts at the time. During May 2021, that consensus is no longer there. When we see Dr. Fauci admitting he cannot exclude it whil WP users on this page feel they know better than him by being able to revert by just stating "Not true" and calling Science "crappy sourcing", then we have moved away from reflecting current academic debate to instead put up some WP users as the experts. That's not how it's supposed to be. Sure, covering Covid is challenging as science continue to learn more about it at a rapid pace - but that's no excuse for us to ignore it. Jeppiz (talk) 10:57, 24 May 2021 (UTC)
 * The situation has not changed, in the best sources. No decent source "excludes" the extremely unlikely possibility of a lab leak, and neither does Wikipedia - so that would seem to be a straw man point. When/if the science moves on as reported in solid RS (as opposed to the politics/journalism/letters and otherwise lesser sources), then we can adjust accordingly. Until then how it's covered in Wikipedia looks sane. (Quite apart from anything else the premise as stated here, "Covid-19 might have escaped from a laboratory", is nonsensical, COVID-19 is a disease and this is the article about that disease. The article about the virus is Severe acute respiratory syndrome coronavirus 2.) Alexbrn (talk) 11:08, 24 May 2021 (UTC)

Semi protected edit request - 30 May 2021
http://doi.org/10.1210/jendso/bvab037 This secondary review article from the University of Oxford summarises six large scale research papers confirming a) the role of sugar (fructose) in the development of severe COVID-19, and b) how this factor is likely to affect vaccine efficacy.

Suggested edit: Under section 6.8 "Healthy diet and lifestyle" at the end of the first paragraph, add "The University of Oxford recommends limited fructose consumption in order to minimise inflammation, a key contributor to morbidity in COVID-19 "

New Lab Leak Evidence
There has been new lab leak evidence and has been displayed in the reliable sources like The Daily Telegraph and Financial Times, so why does this article not include these and because of this new evidence why doesn't it label the nature emergence of the virus as a conspiracy theory? The new evidence can be found here. unsigned comment by 
 * Welcome to Wikipedia! Unfortunately, your edits had a few issues. Most notably from what you mentioned above, the Daily Telegraph is not a very reliable source, particularly for the claims being made. We generally follow a policy to favor WP:SCHOLARSHIP over news sources (especially useful, since I could find another news article contradicting the one you posted), when available, and those sources don't reflect what you wrote. Which brings me to the second concern, we also follow a policy of neutral point of view writing, meaning that no matter how much we're convinced of something, we still need to present things from a neutral viewpoint. So phrases you used, like "appeared to be scared" and "it emerged" are avoided for the connotations they give (see Words to Watch). You may find it beneficial to edit other areas of Wikipedia outside COVID-19 topics while you learn your way around the policies, and how to write encyclopedically. Especially as there are relatively strict sanctions around the topic due to their contentious nature. I hope that helps explain. Bakkster Man (talk) 18:47, 5 June 2021 (UTC)


 * The trouble is no source is completely accurate even if we go by government sources like the BBC or other newspapers.

Possible infections among WIV researchers in November 2019
This article, published on June 3, 2021, says the following:


 * Three researchers at the Wuhan Institute of Virology, all connected with gain-of-function research on coronaviruses, had fallen ill in November 2019 and appeared to have visited the hospital with symptoms similar to COVID-19...


 * While it is not clear what had sickened them, “these were not the janitors,” said the former State Department official. “They were active researchers. The dates were among the absolute most arresting part of the picture, because they are smack where they would be if this was the origin.” The reaction inside the State Department was, “Holy shit,” one former senior official recalled. “We should probably tell our bosses.” The investigation roared back to life.

Earlier estimates of IFR
In the section titled Earlier estimates of IFR, the first sentence is: "At an early stage of the pandemic, the World Health Organization reported estimates of IFR between 0.3% and 1%." This range (0.3% - 1%) is what is stated in the first reference from the end of february 2020 (WHO Situation Report – 30), however there was a correction the next day in the second reference (WHO Situation Report – 31) where they replace the lower bound: "Since the publication of modeling estimates in yesterday’s ‘Subject in Focus’, one research group (Ref. 12) has provided a correction of their estimate of the Infection-Fatality Ratio (IFR), with the new estimate being 0.94% (95% confidence interval 0.37-2.9). This replaces the lowest estimate of IFR of 0.33%, but remains below the highest estimate of 1.0% (Ref. 11)." In the correction they don't mention the new lower bound but if I read the papers that the WHO references correctly the new range was about 0.5% - 1%. --78.82.228.158 (talk) 22:57, 30 June 2021 (UTC)

Discrepancy between cited source and a sentence in the long-covid section
The section "Longer-term effects" reads like a majority of people who got COVID will have long-term lung damage (28+ days). It states that "The majority of CT scans performed show lung abnormalities in people tested after 28 days of illness.[257]". Checking the source, the word "majority" never occurs and the only percentage mentioned is 98.1% (quite a bit more than a "majority"). Looking for the number 28 (days), it is also only ever mentioned in relation to this 98.1% figure. The source is about "Studies on radiologic progression of severe COVID-19 infection" (severe cases only) and "the current literature on the clinical and radiologic manifestations of post-recovery COVID-19 toward the end of hospital admission and after discharge" (hospitalized cases only) rather than anyone who had COVID-19. There does not appear to be a study cited that did chest CT scans on non-hospitalized or non-severe COVID-19 cases, i.e. nothing can be said about that group (let alone the asymptomatic group) based on this citation. The current text seems inaccurate to me.

Feel free to improve/alter the suggestion, but looking at other edit requests, I see that one should provide an exact from-to change request. I would propose to replace this text:

"The majority of CT scans performed show lung abnormalities in people tested after 28 days of illness."

With:

"Among severe cases of hospitalized patients it was found that 'up to 98.1% of all chest CTs will show abnormalities at > 28 days since symptom onset'."

 * Good catch.

Severity was based on the CT findings, not necessarily the clinical appearance. MartinezMD (talk) 17:37, 9 July 2021 (UTC)

 * VAERS is a public reporting system. You can – and someone once did – report that you turned into a green-skinned, muscle-bound Hulk after a vaccine.  There are reports of car wrecks "caused" by vaccination.  (This is not entirely implausible; think about how many people feel faint at the sight of a needle, or think they're too tough or too busy to sit around for 15 minutes to make sure that they aren't having an allergic reaction.)  When you vaccinate millions of people, especially if you focus on vaccinating people who are already seriously ill, you expect a small percentage of people to die "after" being vaccinated.  That doesn't mean that the vaccine directly caused it, and it definitely doesn't mean that getting COVID-19 would be safer. WhatamIdoing (talk) 15:55, 22 July 2021 (UTC)

Variant comparisons
I think the last sentence on the SARS-CoV-2 variants para is misleading:

Using whole genome sequencing, epidemiology and modelling suggest the Alpha variant VUI-202012/01 (the first variant under investigation in December 2020) in the B.1.1.7 lineage transmits more easily than other strains.[76]

This could be taken to mean alpha is generally more transmissible then beta, gamma, delta, which might be the face value meaning for a non-specialist. However checking reference 76 the "other strains" generally predate the other variants listed. My suggestion is that as a minimum this is changed to:

transmits more easily than other strains known at the time.[76]

But ideally updated by a specialist using the correct terminologies (strain/variant/...). WelchsUK (talk) 22:42, 11 August 2021 (UTC)

A study on 17,171 suspected COVID-19 patients demonstrating the diagnostic accuracy of RAT kits in diagnosing SARS-CoV-2 revealed that RAT kits show a pooled specificity of 99.4% (95% CI: 99.1–99.8) and sensitivity of 68.4% (95% CI: 60.8–75.9). In this study, nasopharyngeal specimens and symptomatic patient’s samples were more sensitive in RAT, while cycle threshold (Ct) values were found to have an inverse relationship with sensitivity" [Reference]

 * While there is one word glycoprotein in the article, I think there should be a larger discussion of glycans including galectins and the potential for galectin inhibitors.

Minor spelling inconsistencies
The article is meant to be in Hong Kong English, yet many of the words follow American English spelling conventions. For example, "hospitalisation" and "hospitalization" are both present through the article. This isn't a major flaw, but bringing the grammar and spelling into order with the chosen dialect should be a fast and easy thing to fix. 78.152.233.71 (talk) 11:25, 24 July 2021 (UTC)
 * The article is tagged with the EngvarB template, for which the documentation states: – for non-specific but not N. American spelling.

Transclusion citation error in transmission
The first part of the "Transmission" section appears to be transcluded from Transmission of COVID-19. However, the second citation after the sentence "However, infection can occur over longer distances, particularly indoors." does not work properly.

Secondary and tertiary sources being preferred over peer-reviewed primary sources?
This is the first time I've looked through this article and at a glance I am noticing quite a large number of secondary and tertiary media sources being cited over peer-reviewed primary scientific literature that makes the same claim. For example, why is the sentence "Although one Italian study suggests it was present there as early as September 2019." citing Reuters for the claim instead of this easily-accessed primary source? Why is the article like this? Playing a game of telephone with imperfect sources like the Wall Street Journal over a contentious topic of geopolitical significance seems like an almost guaranteed recipe to spread propaganda and spin. 98.127.81.62 (talk) 21:34, 7 September 2021 (UTC)
 * It mostly has to do with adhering to WP:MEDRS, which vastly prefers literature reviews, as that doesn't run the risk of improperly synthesising material or editors coming up with their own conclusions and adding them to the article. — Tenryuu 🐲 ( 💬 • 📝 ) 21:42, 7 September 2021 (UTC)
 * Further, Wikipedia (as an encyclopedia) is a tertiary source. We do not describe "breaking news" for issues in medicine, especially because those primary sources need interpretation and evaluation by experts.  Eve rgr een Fir  (talk) 21:48, 7 September 2021 (UTC)

Unnecessary statement
Am I the only one that thinks the sentence

“In the past, many diseases have been named after geographical locations, such as the Spanish flu, Middle East respiratory syndrome, and Zika virus”

is unnecessary? Thank you, WikiJanitorPerson (talk) 21:52, 7 September 2021 (UTC)
 * It is redundant, and doesn't flow as well as the following (relevant) info: "...per 2015 guidance and international guidelines against using geographical locations (e.g. Wuhan, China), animal species, or groups of people in disease and virus names in part to prevent social stigma."

Prevention Paragraph (5)
I recommend adding "Measures were taken to prevent the spread of Covid-19. In the United States, large gatherings were banned, lockdowns were taking place, and mask mandates were in place." into this paragraph because it sums the precautions that were taken in the United States/around the world. It will make it easier for the readers to understand. — Preceding unsigned comment added by Aweger (talk • contribs) 23:53, 3 October 2021 (UTC)

Symptoms Paragraph
Symptoms: - Headache - Loss of smell or taste - Nasal congestion/runny nose - Cough - Sore throat - Fever - Breathing difficulties For the symptoms paragraph, I would recommend making it a bulleted list, so it is easier on the eyes for readers and is easier to understand. — Preceding unsigned comment added by Aweger (talk • contribs) 23:57, 3 October 2021 (UTC)

Introduction Paragraph
I would recommend adding information about the first case of Covid-19. It talks about when we suspected Covid-19 starting, but do not narrow down the actual date.

Covid-19 is human made
Based on the features revealed from covid-19, it is a human made virus that origins from Wuhan in China. From where Chinese do not eat bat raw and the virus can't exist in temperature over 30 °C, then this can tell there something same as influenza that does not exist anymore and no one remind it too.

Hello, would like to add two medical journal sources for SARS-CoV-2 variants emerging in 2020. Sentence in question is "Several notable variants of SARS-CoV-2 emerged in late 2020." . I also think the wording should be changed from "late 2020" to "throughout 2020" but that's not imperative. The journal links are this one and this one. This should justify the removal of the citation needed template immediately proceeding the full stop. Thanks in advance Obama gaming (talk) 01:11, 22 October 2021 (UTC)

Hello, would like to see if this journal article fits the Medical Citation Needed proceeding the sentence "After strict quarantines and a mink euthanasia campaign, it is believed to have been eradicated." [regarding the Cluster 5 spread in Denmark]. Relevant statements include "leading to the culling of many millions of mink, in fear that the latter would transmit strains more virulent, more contagious, or resistant to vaccines in development", & "Fearful of seeing SARS-CoV-2 variants selected in mink such as “Cluster 5” spread more easily among people, and to be more deadly or to have a negative impact on the deployment of anti-COVID-19 vaccines, the Danish Government decided to cull 17 million farmed mink". There is also another journal article, albeit only available as a PDF but it's free. Thanks in advance. Addenum: this article also seems very useful. Obama gaming (talk) 09:50, 23 October 2021 (UTC)

I asked a question a few days ago. A couple of sections above. Can someone please answer this?103.246.36.61 (talk) 04:41, 24 October 2021 (UTC)
 * The answer is that it's hard to know exactly how many COVID-19 deaths there have been, as different methodologies for estimating the number of deaths yield different totals, although they generally agree that it is close to 5 million. The Reuters article should be good enough for stating that Reuters has reported the death toll as exceeding that number. BD2412  T 04:59, 24 October 2021 (UTC)
