Is Dengue Fever really a problem in East Anglia? —Preceding unsigned comment added by 86.134.185.128 (talk) 02:24, 23 December 2007 (UTC) It was for a time, but with the help of Super Sid, Laird of Clenchwarton, it was eradicated with the help of his band of elves and a bucket of love piss[reply]

Your map shows dengue practically absent from Bolivia, but there is an epidemic here. Recently flooding has made things much worse. (RHF)

I'm not a doctor but I do read medical stuff. However not being an immunologist I am confused by many terms in this article, for instance:

enhancement of DHF incidence

DHF is the Dengue virus ("Dengue hemmorhogic fever"). What does "enhancement" mean in this context? Jaysbro 14:53, 17 November 2005 (UTC)[reply]

Response: ADE stands for "Antibody Dependent Enhancement" It that, in a case of infection by a second serotype, the dengue virus gets more virulent the more the immune system tries to fight it.

I redirected Dengue Fever to here from a band article. Someone added a redirect to the band. I don't think this "band" is well known, and needs a redirect from the main page. Tokakeke 22:37, 9 December 2005 (UTC)[reply]

I updated the information for Indonesia, which had a large number of cases in 2005. I wasn't sure what to put on the "date of information." I settled with "Jan. 2006" but perhaps simply "EOY" (End of Year) would be better. 24.124.61.165 23:28, 19 January 2006 (UTC)[reply]

dengue was the most important mosquito-borne viral disease affecting humans after malaria

I remove the viral from this as malaria is not a viral disease. Nil Einne 11:20, 31 July 2006 (UTC)[reply]

I'm surprised that Cuba doesn't appear in the list of recent outbreaks. There clearly is one, and in the German wikipedia they mention that possibly up to 600,000 people are infected... other sources (medical institutes) guess that the number might be some 10.000, but state that no official data is available. [6 October 2006]

I've added some info about it. --Steven Fruitsmaak (Reply) 13:56, 7 October 2006 (UTC)[reply]

Another country that needs attention is Mexico. There are outbreaks every year and we are currently in the middle of one with frequent spraying and the health officials running a door to door campaign. Several people I know have been affected and I believe the figures may be higher than for some of the countries quoted. --189.165.113.234 04:07, 2 March 2007 (UTC)[reply]

The 'Rumoured Herbal Cure' section is poorly written and should be fixed prior to considering this a "good article". [2006 Oct 11]

GA review (see here for criteria)

1. It is reasonably well written.

   a (prose): b (MoS):

2. It is factually accurate and verifiable.

   a (references): b (citations to reliable sources): c (OR):

3. It is broad in its coverage.

   a (major aspects): b (focused):

4. It follows the neutral point of view policy.

   a (fair representation): b (all significant views):

5. It is stable.

   

6. It contains images, where possible, to illustrate the topic.

   a (tagged and captioned): b lack of images (does not in itself exclude GA): c (non-free images have fair use rationales):

7. Overall:

   a Pass/Fail:

• Some sections, especially "Diagnosis" and "Treatement" needs a rewrite to be comprehensive (1a)
• Section "Recent outbreaks" needs to adhere the list guideline (1c)
• Some jargon is not defined, and some words are defined in it's second part.

As it's bothe 1a and 1d, I fail this nomination, better luck when these points have been adhered. Otherwise it's a good article, the section "Signs and Symptoms" was promising. _→AzaToth 14:31, 14 October 2006 (UTC)[reply]

In the Treatment section, the herbal treatment for Dengue through the consumption of juice made of papaya leaf seems to be an urban legend and do not provide any factual evidences. This could be wrong information. —The preceding unsigned comment was added by Niranjansm (talk • contribs) 09:52, 16 Oct 2006 (UTC)

I have reverted the addition of "Papaya Juice - Cure for Dengue" section, and it seems like it was reverted once before.--DO11.10 18:02, 16 November 2006 (UTC)[reply]

The article currently states: "Cases of DHF also show higher fever, haemorrhagic phenomena, thrombocytopenia and haemoconcentration. A small proportion of cases lead to dengue shock syndrome (DSS) which has a high mortality rate." "High" is a relative term. Does it mean 1 in 50 will die? 1 in 8? 1 in 1,000? Can we define it more presicely? Also, that sentence could use a source. Johntex\^talk 03:00, 6 March 2007 (UTC)[reply]

"It may also cause yeast infections to the genital area if left untreated for a long period of time." -- Could we have a cite for this? The connection doesn't seem obvious. -- 201.51.222.169 22:33, 8 May 2007 (UTC)[reply]

I had just been looking into this statement as you wrote your query. I've been unable to find a source for the statement, so I've removed it pending a reference. -- MarcoTolo 22:37, 8 May 2007 (UTC)[reply]

I know that malaria comes back. My elderly father seems to have a relapse from an infection in WWII. There is no mention of this on the page. Is it possible? 144.134.129.216 22:59, 2 June 2007 (UTC)[reply]

Dengue Fever does not have relapses, as far as I know. Any relapsed condition is either due to new infection or a different disease. There is no in-body reservoir for Dengue as there is for Malaria. OcciMoron 20:08, 15 August 2007 (UTC)[reply]

The etymology section seems strangely placed. I think it should move to later in the article, in the history section, and have edited to do this, but I think it's worth discussing. OcciMoron 20:16, 15 August 2007 (UTC)[reply]

quoting: "often found in urban areas of developed tropical nations, including Singapore, Taiwan or Rio". Is it my understanding of the sentence or does it actually say that Rio is a nation? I'm changing it to Brazil, if anyone thinks I misinterpreted it feel free to reply. —Preceding unsigned comment added by PrestoK (talk • contribs) 13:17, 25 October 2007 (UTC)[reply]

Taiwan is a tropical nation, Rio is an urban area of a tropical nation. Mixing the two is incorrect, yes. --Chriswaterguy talk 06:50, 13 November 2007 (UTC)[reply]

quoting " One major difference, however, is that malaria is often eradicated in major cities, whereas dengue is often found in urban areas of developed tropical nations, including Singapore, Taiwan, Brazil & East Anglia."

East Anglia is a region of the UK and is certainly not tropical or urban —Preceding unsigned comment added by 81.157.197.221 (talk) 13:41, 21 December 2007 (UTC)[reply]

"Dengue fever (IPA: /ˈdɛŋgeɪ/) and dengue hemorrhagic fever (DHF) are acute febrile diseases, found in the tropics and Africa, and caused..." Gee, and I had that weird misconception that Africa was in the tropics...200.244.240.42 (talk) 17:52, 14 April 2008 (UTC)[reply]

That's why they call it a misconception. It's a fancy word that means YOU ARE WRONG. There's a new invention. It's called an atlas. Perhaps you've heard of it. —Preceding unsigned comment added by 216.49.77.67 (talk) 22:02, 11 July 2008 (UTC)[reply]

How long between getting bitten and getting the first symptoms? That would be very useful information (e.g. in helping diagnosis, by considering where one has traveled - if it takes at least a week and you've only been in a Dengue area for 3 days, then probably those symptoms aren't Dengue.) --Chriswaterguy talk 06:50, 13 November 2007 (UTC)[reply]

This is very important, please add something to this effect, thanks. —Preceding unsigned comment added by 189.62.207.114 (talk) 01:25, 1 October 2009 (UTC)[reply]

The article does not make connections between dengue fever, DHF and DSS. I find in another source that DHF may occur when the patient has already had an earlier case of the milder dengue fever. Is Dengue Shock Syndrome a development of DHF? Or does it also emerge by itself? As a consequence of earlier infection with dengue fever? It would be helpful if all this were laid out methodically. Thanks. NaySay (talk) 18:56, 13 December 2007 (UTC)[reply]

"... one of the many ongoing vaccine development programs is the Pediatric Dengue Vaccine Initiative which was set up in 2003 with the aim of accelerating the development and introduction of dengue vaccine(s) that are affordable and accessible to poor children in endemic countries."
This somewhat resembles adspam to me. Is it? -- Writtenonsand (talk) 16:59, 21 March 2008 (UTC)[reply]

The Total at the bottom is not the sum of the numbers above... and the footnote only confuses things more since it says the totals are only for the listed countries (but that doesn't work out mathematically). Unless I'm missing something in which case it should be rewritten to be more clear. —Preceding unsigned comment added by 198.239.151.48 (talk) 20:39, 15 April 2008 (UTC)[reply]

Superinfection is infection with a different strain of the same organism when there is already one strain of that organism present.

"Through an immunological phenomenon, known as original antigenic sin, the immune system is not able to adequately respond to the stronger infection, and the secondary infection becomes far more serious.[10] This process is also known as superinfection.[11][12]"

That statement doesn't describe superinfection; it describes a second infection later in life with a different strain to the first, once the first infection has been cleared. Original antigenic sin means that the body will produce antibodies to the first strain instead of the second. The second infection becomes more serious because of the Halstead effect (aka ADE) described just before this statement - i.e. antibodies against the first strain do not neutralise the second strain, and instead enhance uptake of the viruses into the monocytes / macrophages, where they replicate.

Also, the second infection is not necessarily stronger, only poorly addressed because of original antigenic sin.

Comma removal x1. Add "humoral"

I would replace with:

"Through an immunological phenomenon known as original antigenic sin, the humoral immune system is not able to adequately respond to the second infection, resulting in antibody-dependent enhancement, and the infection becomes far more serious.[10]"

References 11+12 would therefore fall away, as they have no relevance to the topic. KosherPork (talk) 18:43, 27 November 2008 (UTC)[reply]

Note: There is now an article on dengue in Bolivia. --Candlewicke _S^T _# :) 16:18, 27 February 2009 (UTC)[reply]

The order of sections seems a bit odd. As of 2 Nov 09 it is

  * 1 Signs and symptoms
   * 2 Diagnosis
   * 3 Etiology
   * 4 Treatment
         o 4.1 Traditional and emerging treatments
   * 5 Epidemiology
   * 6 Prevention
         o 6.1 Vaccine development
         o 6.2 Mosquito control
         o 6.3 Potential antiviral approaches
   * 7 Etymology
   * 8 History
   * 9 Use as a biological weapon
   * 10 External links
   * 11 See also
   * 12 References

In particular Prevention should go before Treatment. Perhaps it should be (I've left the original numbers)

   * 3 Etiology
       * 9 Use as a biological weapon
   * 8 History
   * 5 Epidemiology
   * 6 Prevention
         o 6.1 Vaccine development
         o 6.2 Mosquito control
         o 6.3 Potential antiviral approaches
   *   Diagnosis (section containing 2 subsections with no preceding text)
        * 1 Signs and symptoms
        * 2 Criteria for diagnosis (was top-level diagnosis section)
   * 4 Treatment
         o 4.1 Traditional and emerging treatments
   * 7 Etymology
   * 10 External links
   * 11 See also
   * 12 References

I haven't thought this through carefully, so it needs to be discussed before anything is actually changed. Pol098 (talk) 14:58, 2 November 2009 (UTC)[reply]
