Talk:Orthomyxoviridae

type A flu=Avian flu?
English has plenty of misnomers. If there is at some time in the future a type A that doesn't infect birds, then "avian flu" will be a misnomer for that postulated type A subtype. Whether the English speaking world at that time draws a distinction between "type A" and "avain flu" is for those speakers to decide. Some may make one choice and others make another choice (based on nationality or some other thing). We here and now are in no position to assert what "must" happen in such a postulate case. The term "avian flu" is in the hands of the public at this point. WAS 4.250 15:13, 31 October 2005 (UTC)

Genera of Orthomyxoviridae
WAS 4.250:

I'd like to thank you first of all for the attention you've given to H5N1-related articles on Wikipedia. They're mostly of poor quality, and they remain that way because the subject is a highly technical one that is not easy for the non-expert to accurately write about. The efforts of some Wikipedians such as yourself have improved them very considerably, but there are still problems. I think they'll be much better in a few months.

With respect to this edit, the reasons I made the changes are: Would you mind my reverting the page? Regards encephalon  06:27, 13 November 2005 (UTC)
 * 1) Avian influenza is not a genus of Orthomyxoviridae. The term "avian infuenza" denotes a disease—it is influenza that affects birds. The term is frequently misused and misunderstood by lay people (a problem reflected on Wikipedia).
 * 2) The orthomyxovirus family consists of 5 genera: Influenzavirus A,  Influenzavirus B,  Influenzavirus C, Isavirus, and Thogotovirus. Influenzavirus A is not the same as "avian influenza": the former is a genus of viruses, the latter is an illness. This too is misunderstood on Wikipedia. Equating them is like saying Streptococcus pneumoniae is pneumonia, or HIV is AIDS.
 * 3) H5N1 and H1N1 are not type species of the genus Influenzavirus A. H5N1 is a subtype of Influenza A virus, which is a species of Influenzavirus A. There are many, many, many subtypes of the Influenza A species. Each subtype in turn has dozens or even hundreds of strains (there are more than 400 different strains of the H5N1 subtype alone).
 * 4) I am aware that Influenzavirus A and Influenza A virus are links—I created the pages. I created them primarily as temporary redirects, for the benefit of people who were searching for information on H5N1. However, they are not suitable as targets in this article on orthomyxoviridae, because they do not explain Influenzavirus A nor Influenza A virus. The pages redirect to the article H5N1 (or they used to before this). If you are reading the article Orthomyxoviridae and come across the link Influenzavirus A, it is reasonable to expect that you'll be taken to a page that explains what that means when you click on it. Currently, that is not the case. When the family of articles on this vast subject is completely written, those links would be perfectly appropriate, but not now.

Contradiction
Hi guys

This article contradicts the linked article on antigenic shift, which states that:

"Influenza A viruses are found in many different animals, including ducks, chickens, pigs, whales, horses, and seals. Influenza B viruses circulate widely only among humans."

Actually, I'm pretty sure your Orthomyxoviridae article is the correct one (see http://news.bbc.co.uk/1/hi/sci/tech/744945.stm). ...I'll put a post up on the antigenic shift discussion page.

It might be helpful to emphasise that influenza A is MUCH more widely distributed amongst non-human hosts, hence antigenic shift, and that influenzas B and C are pretty much confined to human hosts hence antigenic drift. Note, only one incidence of influenza B has so far been found in a non-human host - in an isolated population of seals.

Invertebrates?
I do not believe it is appropriate to use the term infection when referring to the invertebrate - the invertebrates (tick and louse) are vectors that carry and transmit the virus without (to my knowledge) themselves becoming sick. This is common with insects and other arthropods (see this link for some examples ). I have never seen the vector described as being infected, and this principle carries in the articles that are cited in the Orthomyxoviridae lead paragraph. Hope this explains my edits are with good intention! Ciar 16:22, 1 June 2007 (UTC)


 * I looked again at the sources and they say the ticks are infected but the sea louse only possibly is infected but definitely transmits. Being sick isn't required for the term "infected" by a virus. If the virus can infect a cell and multiply, it is infection. WAS 4.250 17:26, 1 June 2007 (UTC)


 * Point taken on the ticks! However, the way the article stands, the links are going to the wrong place (i.e. reference 1 just points to a page listing the taxonomy of Thogoto virus, which only mentions vertebrate infectivity) while the ref with the relevant info is not visibly linked in the main article. I don't want to just jump myself in and change what you just added ;-). Thanks for considering my interpretation!! Take care, Ciar 17:53, 1 June 2007 (UTC)


 * Take a second look. Footnote number one lists three seperate sources, the second of which has a quote. WAS 4.250 23:32, 1 June 2007 (UTC)

Moved for insertion into article
The following section was abbreviated in the article 2009 swine flu outbreak and the entire section placed here for possible insertion of facts into this article, where relevant and not redundant. --Wikiwatcher1 (talk) 21:35, 15 May 2009 (UTC)

Section 3.2 Genome Suggestion
If anyone is watching this Section 3.2 just seems to be a bunch of words strung together. What is it trying to say? That there are repeats at 5' and 3' ends? OK. What's with all the ...of... ..of.. ...? Is this how long the strands are, how long the segments are or what? I will leave the text in place for a while so someone who knows what was trying to be said can clean it up. Otherwise I am going to remove the section because A) It makes no sense. B) There is nothing saying why whatever is being said is important. As it stands this section does not help the article. Jbhunley (talk) 14:56, 25 December 2014 (UTC)

Subtypes
According to https://www.fhi.no/nettpub/smittevernveilederen/sykdommer-a-a/influensa/ (in Norwegian) and https://en.wikipedia.org/wiki/Influenza_A_virus, there are now 18 H-antigen subtypes and 11 N-antigen subtypes. Georg Muntingh (talk) 07:12, 3 February 2020 (UTC)
