== Deletion of [[:File:Hepatitis.gif]] ==

This is a pretty table image, but I am preparing to delete it because it has numerous factual errors and cannot be edited directly.  It should probably to replaced with a wiki-table to support collaborative editing.  Here are a few of the problems:
:''Transmission'':
::"Parentral" should be "parenteral"
::Maternal-fetal transmission should also be listed, particularly for HBV since that's the #1 mode worldwide
:''Classification'': 
::HEV is not a calicivirus (also note spelling error "calcivirus"), it is a hepevirus
::HCV is not a flavivirus, it is a member of the Flaviviridae
::HDV is a "Deltavirus"
:''Viral antigens'' (presumably this is the ones for which tests exist):
::HAV: does not have any antigen test licensed, does it?
::HEV: does not either
::HBV: HBcAg should be removed
::HCV: Core antigen should be the only entry
:''Chronic hepatitis'':
::The cryptic abbreviation "a/c" should not be used here
That is why I'm deleting.  Re-creating this as a table, for those who are proficient in such things, seems like a good idea.  --[[User:Scray|Scray]] ([[User talk:Scray|talk]]) 12:16, 10 February 2009 (UTC)


Ok.Thank you for the details.HEV is calicivirus in the microbiology textbook we follow and its the same in most websites.But hepevirus seems to be the right version as per new sources on the web.
Have uploaded new image with the changes as per your instruction.

Have simplified the antigens section.
Will be adding the image back to hepatitis after the changes.Please do revert if needed.

-thank you

@ Scray 
Have replaced image with a wiki table.That is my first table by the way.Please edit the data if  required.The image looked attractive than the present wiki table.But,it will be better once some color is thrown in to those columns.

:Nice work!!  That is definitely an improvement - accuracy and collaborations are more important than aesthetics. I wonder whether this more properly belongs on the [[Viral hepatitis]] page, though?  Let's see if anyone else comments and get a [[WP:Consensus|consensus]].  Also, I am not proficient with tables, but other editors are.  --[[User:Scray|Scray]] ([[User talk:Scray|talk]]) 22:21, 10 February 2009 (UTC)

Can you give me the 'families' of Hepatitis viruses A to E please?Can add to the table.
And should 'Classification' be changed to 'Type' ?

[[User:Nishanthb|Nishanthb]] ([[User talk:Nishanthb|talk]]) 03:01, 11 February 2009 (UTC)

:You can find the families of the respected viruses in their own articles—look for the [[Template:taxobox|taxobox]], although I would question the necessity. While comparing the images and the table, there are some missing points such as "Chronic Hepatitis" and "Symptoms"; although it may be reasonable to assume that some of them may be unnecessary, I can add them if you want (use the colspan attribute to get table cells to stretch across multiple columns).<p>A lot of the information in the table are provided in the linked articles, and reproducing (here at least) seems to be an overemphasis and a perhaps a waste. In my opinion I believe the best course of action would be to begin a section in [[Viral hepatitis]] discussing the multiple viruses holistically (in prose) with this table giving a quick and easy method of understanding the comparisons. I can begin if you guys want, however let's try for a consensus first so that we don't have to keep revising each other's edits. [[User:ChyranandChloe|ChyranandChloe]] ([[User talk:ChyranandChloe|talk]]) 04:02, 11 February 2009 (UTC)

The 'Chronic hepatitis' column can be added.The details can be limited to 'No' and 'Yes' if the % details make the table cluttered.

This table can be moved to Viral hepatitis too as it is.
We can add more clinical features and treatment modalities of the different hepatitis which will probably make the table relevant in an article on hepatitis.I favor tables and believe its easier for new readers  to understand the facts when they can be effortlessly compared.Also it may be alright to float the table to the right of the list of links in subsection 'Types' so that it doesnt expand the article vertically. [[User:Nishanthb|Nishanthb]] ([[User talk:Nishanthb|talk]]) 04:56, 11 February 2009 (UTC)

:{{done}} See [[Talk:Viral hepatitis]] for the new discussion. [[User:ChyranandChloe|ChyranandChloe]] ([[User talk:ChyranandChloe|talk]]) 04:41, 12 February 2009 (UTC)

Fine.Thank you.[[User:Nishanthb|Nishanthb]] ([[User talk:Nishanthb|talk]]) 14:35, 12 February 2009 (UTC)

== MEDMOS ==

I have had a quick stab at organising this in a [[WP:MEDMOS]] kind of fashion. The best source for this kind of content is probably the average medical textbook, because few high-quality [[WP:MEDRS]] will be devoted to undifferentiated hepatitis.

The section discussing all the subtypes could easily be shortened to the bare minimum, because there are subarticles for all of them.

I'm not sure how much content should be placed in a "diagnosis" or "treatment" section. I don't think there is a "generic" approach to the treatment of hepatitis. With regards to diagnosis it might be nice to make a reference to the "full liver screen" (UK terminology) or the "liver database" (USA terminology). [[User:Jfdwolff|JFW]]&nbsp;|&nbsp;[[User_talk:Jfdwolff|<small>T@lk</small>]] 18:47, 10 March 2010 (UTC)
:I made some additions to Diagnosis section. The serology tables are nice but I think too much detail. I created Viral hepatitis subsection for the existing Hep A & C content. I would like to add Hep B and consider removing some of the detail here. This is the model I would propose for the Treatment section (along with Epidemiology and Prevention when I get there): brief general intro followed by specific details about viral hepatitis since it is the most prevalent. [[User:Emhawkins|Emhawkins]] ([[User talk:Emhawkins|talk]]) 07:09, 5 December 2013 (UTC)

== Redirect from [[Hepatitis virus]] ==

This redirect does not seem to be appropriate, because all types of hepatitis are explained. Instead, "Hepatitis virus" should redirect to [[Viral hepatitis]]. Then this lemma can be linked in the introduction: "A group of [[virus]]es known as the [[Viral hepatitis|hepatitis virus]]es cause most cases of hepatitis worldwide, ...". If there are no reasons against it, I'll change the redirect. --[[User:Jwollbold|Jwollbold]] ([[User talk:Jwollbold|talk]]) 11:35, 5 January 2011 (UTC)

== Completeness? ==

Should this page also include links to hepatitis F and hepatitis G ...? I ask because the hepatitis A page links to both of those.  <span style="font-size: smaller;" class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/82.1.117.11|82.1.117.11]] ([[User talk:82.1.117.11|talk]]) 10:44, 31 August 2011 (UTC)</span><!-- Template:Unsigned IP --> <!--Autosigned by SineBot-->

==Parvovirus B19==
{{User|DrMicro}} added [[parvovirus B19]] to the list of viral causes. The reference provided was not [[WP:MEDRS]]-compatible, but only provided limited ''clinical'' information on the natural of parvovirus hepatitis. Looking around on Pubmed, there is very little solid evidence that this is an actual disease entity. {{PMID|12721938}} (2003) reports negative findings of parvovirus in specimens from patients with fulminant hepatitis. I therefore submit that this is not at all clear-cut, and it probably makes sense to provide more definite evidence from a suitable source.

== Sources ==

On 23 November I [http://en.wikipedia.org/enwiki/w/index.php?title=Hepatitis&diff=462168015&oldid=462136561 reverted] the addition of about 10 KB of content relating to infectious agents that have been linked with hepatitis. I have asked {{User|DrMicro}} (on my talkpage) why it is not possible for [[WP:MEDRS]]-compatible secondary sources, such as textbooks, to be used as sources. Instead of coming to an agreement, DrMicro has now reinserted the same content.

Rather than reverting, I have asked on [[WT:MED]] if this is how we want this article to be sourced. I was hoping we might get some further views on this. [[User:Jfdwolff|JFW]]&nbsp;&#124;&nbsp;[[User_talk:Jfdwolff|<small>T@lk</small>]] 15:04, 28 November 2011 (UTC)

== Editing of Alcoholic Hepatitis section ==

For this section, I added a reference from PubMed to a statement that was unreferenced. In my search for a reference, I also found this really nice summary (with references) of evidence from the National Institute on Alcohol Abuse and Alcoholism that focuses on [http://pubs.niaaa.nih.gov/publications/arh27-3/232-239.htm alcoholism and HCV].
This may be of help for future editors hoping to strengthen this section of the entry. [[User:Lauren maggio|Lauren maggio]] ([[User talk:Lauren maggio|talk]]) 20:37, 4 November 2013 (UTC)

*I am considering removing the metabolic disorders, obstructive, alpha-1 antitrypsin deficiency, and giant cell hepatitis subsections as these seem to be either minor causes or hepatitis is a rare side effect. Thoughts? [[User:Emhawkins|Emhawkins]] ([[User talk:Emhawkins|talk]]) 05:51, 26 November 2013 (UTC)
::While segregating rare causes seems reasonable, I'm not sure removing them from this article would improve it. It's reasonable to expect hepatitis when there is a problem with blood supply, and the same goes for problems with obstruction. When you look at a book chapter or review article on hepatitis, how are these causes handled?  -- [[User:Scray|Scray]] ([[User talk:Scray|talk]]) 06:14, 26 November 2013 (UTC)

{{undent}}
The metabolic causes and protein accumulation disorders are usually listed in the differential diagnoses of hepatitis in medical textbooks. If I encounter a person with suspected hepatitis, a "liver screen" will usually include markers of autoimmunity and iron overload. Depending on the scenario (young patients, coexisting lung disease) there might also be testing for the rarer causes such as Wilson's or alpha-1-antitrypsin deficiency. I believe these causes should get at least passing mention on this page.

I am unsure about the rare entity of "giant cell hepatitis". The section was added by {{User|DrMicro}}, who also authored the very long list of infectious causes. [[User:Jfdwolff|JFW]]&nbsp;&#124;&nbsp;[[User_talk:Jfdwolff|<small>T@lk</small>]] 15:39, 26 November 2013 (UTC)

== No hepatitis B and other serious issues.  ==

- This page has sections on hepatitis A and C, but appears to have no reference to hepatitis B, which is deeply confusing to the newcomer. 

- This page is the top google result for 'hepatitis' but does not offer any support for newcomers seeking knowledge on hepatitis A, B, C, and other rarer varieties.  There is no clear way to see that one should go to a different page [[viral hepatitis]] for more information on these varieties. 

- The other wiki page, [[viral hepatitis]] has full details on A, B, C, etc but is missing some information contained in this page. I suggest looking at merging [[hepatitis]] and [[viral hepatitis]]. 

I note that some people have made suggestions for rewriting this page, however they have not yet been implemented. 

For now, I have inserted a few words in the overview suggesting that more information on hepatitis A, B, and C etc can be found at [[viral hepatitis]].  I hope this is ok. I do not wish to reignite old wars if any exist.   I merely wish to assist newcomers who may be in serious need of finding quick information on this condition.

I did not know, when I first came to this page, that hep A, B, C etc are examples of viral hepatitis; and nor would many other people searching for info on these widely publicised types of hepatitis who get directed by Google to this page.  This information is not stated clearly or accessibly *anywhere* on the page.  I will respect Jfdwolff's edit, however there is a moral imperative to be accessible to newcomers on this particular issue, so if  Jfdwolff does not mind, I will add some signposting to where he has indicated the right location for the link is.

== Setting up a "to do" list for improvements to the article ==

These are mostly notes for my own purposes, just leaving them here for the sake of transparency and with the vain hope that someone else might get infected by the [[WP:SOFIXIT]] virus.

*Rewrite lead.
#No medical jargon unless immediately preceded by an explanation (fibrosis, cirrhosis, etc...)
#Account for content of article (diagnosis, etc...)
*Add a mechanism section
*Clean up diagnosis section:
#Move the pathology section under the diagnosis heading
#Provide a summary and clear links to the [[viral hepatitis]] article instead of repeating content in this article
*Add a prevention section
*Add a management section
*Add a prognosis section
*Add an epidemiology section
*Add a history section
