Talk:Norwalk virus group
From Wikipedia, the free encyclopedia
Is there a citation for the assertion that blood type effects the recovery period or reoccurance for the Norwalk virus? I was unable to find a reliable source.
An Absract from the University of Chicago's Journal of Infectious Diseases can be found here http://www.journals.uchicago.edu/cgi-bin/resolve?id=doi:10.1086/339883 in which blood type and Norwalk virus occurance are linked
also the Dec. 2002 Journal of Virology has a detailed account of the linkage of antigens (blood type) and the Norwalk virus here http://jvi.asm.org/cgi/content/full/76/23/12335
The early November / mid November doesn't make sense as the outbreak described as occuring "mid November" occured before the outbreak described as ocurring in "early November".
Apparently (based on Googling for information) Norwalk virus group = Norwalk virus family = Norwalk-like viruses = Noroviruses. However, I am not an expert. Can someone expert confirm this? -- User:213.253.40.180
I've found this too. And from what I've found "Noroviruses" is the new correct name, and we should rename the page, but I thought I should raise it here first. -- ciphergoth 09:04, 2005 Apr 10 (UTC)
The new name (noroviruses) is correct. Traditionally these viruses were called Norwalk or Norwalk-like viruses referring to the discovery of the virus by electronmicroscopy in the fecal samples from children involved in an outbreak of acute gastroenteritis at an elementary school in the town Norwalk, Ohio.
I don't see how this illness can be called both mild and acute.
Severity and time course are different entities.
Indeed. New name for this group of viruses is Noroviruses. They are genus in a family Caliciviridaetogether with Sapporo-like viruses, Lagoviruses and Vesiviruses according to ICTV.
I deleted the line about Lister Centre (Lister Center at the University of Alberta has recently been quaranteened due to an outbreak of the Norwalk virus on site.) that was added due to the fact that it hasn't been confirmed if it was Norwalk. Also, looks like it was a fairly minor outbreak, regardless. Health measures beating Lister bug Darrel UofA 17:44, 3 October 2006 (UTC)
Trust the Gateway to prove me wrong...they've confirmed it is a Norovirus...if anybody wants to put the Lister part back in, by all means do so...I still don't think it's that important. 20:51, 3 October 2006 (UTC)

[edit] Cruise Ships
This bit looked like it was written by a Carnival spokesperson: (Outbreak investigations by the U. S. Centers for Disease Control and Prevention have shown that transmission among cruise ship passengers is almost wholly person-to-person. Cruise ship water supplies have never been implicated.) I did a quick google search, and found plenty that condradicted this. So I changed it accordingly. -- Aaronwinborn 20:11, 16 March 2006 (UTC)
I have only anecdotal evidence, but I used to work on a number of ships during Norwalk outbreaks, and I can assure you that the main means of transmission is from things like door handles, handrails, lift buttons and the like. The water is not the transmission vector.
I changed the cruise ship back to the original, more factual statement "Outbreak investigations by the U. S. Centers for Disease Control and Prevention have shown that transmission among cruise ship passengers is almost wholly person-to-person. Cruise ship water supplies have never been implicated." Outbreak reports are available on CDC website. If you look at the number of passengers who become ill in most cruise ship outbreaks, it is a relatively small percentage of the total number of passengers. I am not sure about waterborne outbreaks, but I know that in foodborne outbreaks, the attack rate much, much higher than what is generally seen on cruise ships. EAH
- I think it is at best misleading to claim that transmission is almost wholly person-to-person. There are numerous cases of norovirus outbreaks on cruise ships that have been proven to have been caused by contaminated food (usually undercooked shellfish). What is the source for the claim that transmission is "almost wholly person-to-person"? That sounds like propoganda to me. What's your source, EAH? (You think everyone on a cruise ship eats from the *one* undercooked batch of shrimp?) The statement is only factual if it is *true*. What's the evidence? In any event, it's false. One norovirus outbreak on a cruise ship in Hawaii was traced to ice. Ice is water, so ice supply is water supply. Another was traced to shrimp. Most are never traced.
- My husband & I just got off the Norwegian Crown (~1,100 passengers, March 12 2007 sailing). Half-way into the 14 day cruise a letter was placed in the cabins stating that there were 118 reported cases. As there was another week to go, I am guessing that the infection rate was well above 10%. This ship visited no US ports and the ship is of Bahamian registry. I am guessing that they did not need to report to the CDC - or no? It was said that there had been cases in the previous weeks, but of nowhere near the infection rate seen during this cruise. Of note, those who came down with the illness (and their cabin mates) were out of quarantine less than 12 hours after sympoms abated.
[edit] complications?
I know this isn't a bulletin board, but my best friend just called me to say he's had it for the last three days and is quarantined. Thing is, he's had kidney failure in the past. He wouldn't listen to any advice I found for him anyway ;-| but can anyone fill me in on recovery time, residual effects etc? He figures he got it from fruit or vegetables at the market; I haven't seen any info on an outbreak locally, which there are sometimes in hospitals and old folks homes; are individual occurrences in the general population documented in any way?Skookum1 07:13, 10 July 2006 (UTC)

- We're talking about one of the most common diseases humans get. There are many occurrences and outbreaks. It seems that right now there are several clusters of norovirus outbreak throughout the United States. (In fact, I just got over an outbreak and my sister is ill right now. Norovirus is the most likely culprit.) About half of the contagious diseases causing nausea or vomiting and diarrhea are caused by norovirus.
[edit] Whitehorse, Yukon
I think around 25 people have been infected here in Whitehorse, Yukon. They noticed it when a bunch of patients had all the same symptoms at the hospital and then nurses and docters started calling in sick. It's not a really big deal so far- is it worth mentioning? ~~Supermal
[edit] Duration of symptoms
Personal and family experience suggests that some of the symptoms may clear in well under a day. In 2001 my household suffered an outbreak in which gastrointestinal symptoms were severe but of relatively brief duration, clearing in 8 to 12 hours. But fever, headache and lethargy persisted for up to 24 hours after the GI symptoms stopped, so that the sufferer tended to stay in his or her bed. Tony 01:54, 20 November 2006 (UTC)
[edit] THE CURRENT "OUTBREAK"
We are in panhandle Florida area and have an entire family unit/two separate households that have been stricken with it, and it won't go away, others around us-not family continue "coming down with it"-other than normal prevention measures, wash hands, clean food areas, wash hands, clean common bathroom areas, wash hands, etc., what else can be done to prevent further spreading!!??? it's a disaster, the numbers are overwhelming!!! God Bless any who get it!-not fun!! [:+{ 24.214.78.236 02:40, 4 January 2007 (UTC)
The washington post reports that only 4 were confirmed sick in the March 2 2007 in a hotel in Crystal City, but that anecdotally up to 150 might have been sickened:

[edit] Introduction
This article's introduction is far too detailed. It would be rather meaningless to the lay person: it sounds like it was lifted from a medical textbook. Perhaps it would help to add more about the social ramifications, and leave facts such as the number of base pairs in its gene sequence for a section in body. Clarkcol 22:39, 10 January 2007 (UTC)
I agree with Clarkcol. The introduction is very medical in nature and doesn't seem to fit as part of an encyclopedic article. Something like the Wikipedia's Malburg virus article is ideal. Trane X 09:51, 25 March 2007 (UTC)
