Bagram Bug[edit]

Just wondering if it would be ok to include Bagram, Afghanistan in the list of significant outbreaks. I came down with "the Bagram Bug" while in Afghanistan from 2002-2003 and as I recall several other troops (U.S. and Great Britain) came down with it and were knocked out of duty for at least a day or two. I was just informed that this is the cause of the Bagram Bug and suppose that I need to find sources to cite the fact before adding it to the list. Anyone have know any good and specific sources to cite (the problem is there are plenty of articles about the Bagram Bug but I haven't found any that ties the NLV to the bug, a medical officer told me about it and personal experience is not cite worthy. Thanks. —Preceding unsigned comment added by 69.133.42.16 (talk) 07:55, 7 February 2010 (UTC)

A&E -- (not defined) in section Course of disease and complication[edit]

What is A&E? There should not be any initials used that assume that others will know what they mean. Franklinjefferson (talk) 03:49, 9 March 2009 (UTC)

A&E stands for Accident & Emergency, it is the UK equivalent of ER. --Footix2 (talk) 10:46, 31 March 2009 (UTC)


Longevity[edit]

Can someone add whether the virus dies naturally without a host? We were all down this weekend. There is bound to be contamination in the house - but for how long? —Preceding unsigned comment added by 69.119.152.47 (talk) 20:54, 26 April 2009 (UTC)

I read that seven weeks is the longest Norovirus can survive in the environment. For the life of me I can't remember where I read it though. -OOPSIE- (talk) 03:18, 6 October 2009 (UTC)
I've added some info on the virus ability to persist outside the human body --Erlend Aakre (talk) 22:56, 27 February 2012 (UTC)

Sufficient Heating[edit]

Where it says, "Norovirus is rapidly inactivated by sufficient heating and by chlorine-based disinfectants...", should it say "Norovirus is rapidly inactivated by sufficient heating of food and by chlorine-based disinfectants..."? I took it to mean environmental heating until my partner pointed out that it probably meant food heating.
Pyotr Goulden (talk) 11:24, 10 January 2010 (UTC)

It means both; steam-cleaning is an efficient way of cleaning carpets following contamination by norovirus. All viruses are susceptible high temperatures because they are made mostly of protein. I agree that "sufficient heating" is vague. I seem to recall that being held at 560 C for an hour inactivates the virus, and higher temperatures are much quicker, but I will have to find a reliable source for this before making any change to the article.

Norovirus is an extremely common cause of gastroenteritis and it is about time we stopped listing outbreaks in this article. None of these outbreaks are notable; outbreaks of this infection occur frequently and everywhere in the world during winter months and often in the summer too. It is enough to say that norovirus is the commonest cause of outbreaks of viral gastroenteritis in adults in the world, and leave it at that. Wikipedia is not a newspaper. I suggest deleting this section and leaving an inline comment that says it should not be added back. Imagine listing every occurrence of outbreaks of the common cold in it's article. OK, norovirus is a nasty infection, but I can't see the point of an ever increasing list of outbreaks. There will be no end to this. If these outbreaks were long-lived and caused deaths then there might be a reason for including them; but they are not. It seems to me that in this case Wikipedia is being used as a blog; it is not, it is an encyclopedia. Graham Colm (talk) 19:37, 7 February 2010 (UTC)

A blog, it should not be, however, for the common person to try to attain an understanding of where and how these strains of virus can be exposed is very helpful in educating and preventing the spread of infections. Although I agree there should not be a long list of outbreaks, I do otherwise think that a few instances of the outbreak could be mentioned, especially to touch upon a few cases where causes are different in which they have to do with various food contamination, surface contamination, human-to-human contact, as well as geological factors.

Vandalism[edit]

Undid references to some guy whose vandal friends (vandalism from IP 205.202.121.6) apparently thought it'd be fun to blame him personally as a cause of the Norovirus. Garykempen (talk) 15:43, 6 February 2009 (UTC)

Pathology[edit]

Do you think there should be more about why it has the effect it does -- what its interaction is with its human host and why it produces these particular symptoms. It could perhaps be done by linking to relevant other Wikipedia pages. —Preceding unsigned comment added by 77.100.77.248 (talk) 01:57, 7 January 2011 (UTC)

Introduction[edit]

The introduction currently states that persons with AB blood type are more susceptible, and that AB and O blood types provide a degree of protection- it is not possible for AB to be both protected from, and have increased susceptibility to, norovirus.— Preceding unsigned comment added by 148.122.12.122 (talkcontribs)

Yes, there is a problem here. It is actually far more complicated, see: Shirato H (2011). "Norovirus and histo-blood group antigens". Jpn. J. Infect. Dis. 64 (2): 95–103. PMID 21519121. . It depends to some extent on blood group secretor status and the genotype of the virus. I will fix this later, meanwhile I am hiding the confusing text in the article. Graham Colm (talk) 21:02, 24 February 2012 (UTC)

The second paragraph states "severe illness is rare", but later the same paragraph states "causes over 200,000 deaths each year". Should the "rare" statement be qualified to avoid this apparent ambiguity? --John Haigh CA (talk) 18:39, 30 March 2014 (UTC)

PCR does work[edit]

I took out "However, routine methods to detect the virus on other food items are not readily available because of the variable nature of different food items affecting concentration and extraction of the virus and presence of factors that make polymerase chain reaction analysis techniques ineffective." ...because it's wrong, that's not what the study cited says at all. PCR works, albeit with modifications, and it doesn't say anything about other food items. 65.27.134.29 (talk) 02:03, 6 March 2012 (UTC)Ubiquitousnewt

Transmission via Skype[edit]

There's this funny line at the very end of the "Transmission" section: "In a 2012 study, it was noted that the virus can also be transmitted through Skype." That's really funny, but you should remove this, though. — Preceding unsigned comment added by 213.226.141.173 (talk) 23:55, 2 January 2013 (UTC)

Notovirus[edit]

What's a Notovirus supposedly found in mice in the US desert southwest? I can't find a reference anywhere. Bogus? Virgil H. Soule (talk) 07:56, 10 January 2013 (UTC)

But it seems to be sourced, you checked the source? OccultZone (talk) 22:57, 28 January 2014 (UTC)

Merge[edit]

"Norovirus" is a genus name, and there is only one species in the genus, namely Norwalk virus. The International Committee on Taxonomy of Viruses says we should use the name Norwalk virus when talking about it (see link at Norwalk virus). So I think this article should be merged with Norwalk virus. The title should be Norwalk virus, and most of the mentions of "norovirus" should be changed to "Norwalk virus" – unless it's talking specific'ly about the genus (in a theoretical sense, since there's no other species!). Eric Kvaalen (talk) 07:05, 21 November 2014 (UTC)

I disagree with this proposal. Government Health Authorities have yet to catch up with the ICTV. Signs in hospitals still use the term norovirus and the results Google and Pubmed searches for norovirus outnumber Norwalk virus by 3:1. Ironicaly, the ICTV changed the name from Norwalk to norvirus only a few years ago and the change back has not been met with any enthusiasm by healthcare providers. If we revert to using "Nowalk virus" at this time it will make WP look outdated to most general readers. Graham Beards (talk) 09:10, 21 November 2014 (UTC)
WP:COMMONNAME applies. No need for page move. JFW | T@lk 22:47, 25 November 2014 (UTC)
