Talk:Measles

From Wikipedia, the free encyclopedia
Jump to: navigation, search
Former good article Measles was one of the Natural sciences good articles, but it has been removed from the list. There are suggestions below for improving the article to meet the good article criteria. Once these issues have been addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake.
edit·history·watch·refresh Stock post message.svg To-do list for Measles:

Here are some tasks you can do:


Infectivity period[edit]

Can we discuss please the infectivity period? The article says:

"and infectivity lasts from two to four days prior, until two to five days following the onset of the rash (i.e. four to nine days infectivity in total) [2]"

while the source that was cited says:

"The infection has an average incubation period of 10-12 days (range 7-18 days) and infectivity lasts from 4 days before the rash of measles appears until 4 days after it disappears.[3]"

which I think is quite different to what the article days. The source "[3]" adds nothing new to this in my view.

I find all kinds of differing answers on this in the net and I think it would be great to get a definitive answer.

As I am not knowledgeable in this area myself, it would be great if experts could have a look.

Thanks!

with no one having answered I took the liberty to include both beliefs in the article. Happy to discuss Jaeljojo (talk) 19:22, 22 January 2013 (UTC)
I'm not an expert on this, but if you have lingering questions, please as people at WT:MED to comment. Thanks! Biosthmors (talk) 19:34, 22 January 2013 (UTC)
thanks, will do Jaeljojo (talk) 19:42, 24 January 2013 (UTC)

Recent Outbreaks[edit]

Is Sydney the capital of Australia? "In November 2011, an outbreak was reported in Sydney, the capital city of Australia with at least 12 reported cases.[76]"? I'm pretty sure it's Canberra [1] 82.44.75.170 (talk) 21:32, 16 April 2013 (UTC)

Correct. Capital of NSW, or major city. Nice place. Midgley (talk) 00:07, 20 April 2013 (UTC)

According to the New Zealand herald, online Sunday 21 April 2013, "Suspected measles death in UK sparks wave of vaccinations". More at: http://www.nzherald.co.nz/world/news/article.cfm?c_id=2&objectid=10878815 Kdarwish1 (talk) 05:40, 21 April 2013 (UTC)

I know this section is already flagged for clean-up, but I wanted to point out that the following statement is false/misleading: "Vaccination is not mandatory in Europe, in contrast to the United States and many Latin American countries, where children must be vaccinated before they enter school" (end of paragraph 9). Although most parents in the U.S. do immunize their children, it is not actually a law. K.Grey (talk) 17:21, 12 June 2013 (UTC)

"There are suggestions below for improving the article to meet the good article criteria."[edit]

Actually, there are not. Midgley (talk) 00:15, 20 April 2013 (UTC)

I've provided a couple of examples for potential improvement in new sections on this talk page. Additionally, a lot of the recent outbreaks listed have not had followups that discuss the outbreaks as if they have already passed.
In August 2011, an outbreak in New Zealand has seen 94 confirmed cases in Auckland alone. - This right here is an example of what I am talking about. "Has seen" implies the outbreak as still currently occurring, and the article sourced comes from the time period of the outbreak, so more recent sources are needed for some of these.
It also might not be needed (or notable) to include smaller outbreaks of <50 or <100 people as these small outbreaks occur in even the most developed countries every now and then. Or at least these smaller outbreaks should be merged into paragraphs. ComfyKem (talk) 21:00, 29 April 2013 (UTC)

Outdated graphs[edit]

There are four epidemiological graphs on the Measles page: two showing measles incidence before and after vaccine introduction, one showing vaccine uptake in every country and another showing the disability-adjusted life year (DALY) for every country. All of these seem to be outdated by a few years, but the two that necessitate newer statistics are the vaccine uptake graph and the disability-adjusted life year graph. The DALY graph is showing 2002 stats and the vac rate graph is showing 2007 stats, yet the year we are in appears to be 2013(and the Measles Initiative has done a lot of work in recent years), and as such, more up-to-date graphs are needed. I believe the WHO provides these stats, so could someone update them or explain how to? ComfyKem (talk) 20:35, 29 April 2013 (UTC)

Merging sections[edit]

Should the evolution and genotype sections be merged into the cause section as subsections? Cause is discussing the virus, yet the article as a whole is centered around the disease. Diseases don't evolve or have genotypes, but viruses do. ComfyKem (talk) 20:39, 29 April 2013 (UTC)

These sections IMHO should be moved to a new article on the Measles virus rather than being included in this article. The split between the virology of a disease and the clinical features of a disease is fairly standard on WP at this point. This arrangement is a lot easier to work with.DrMicro (talk) 08:15, 3 May 2013 (UTC)

Mortality[edit]

It says, under "Epidemiology", that "In sub-Saharan Africa, mortality is 10%." This is far excessive. Since there are 3-2 × 107 cases worldwide per year, and only 139,000 are fatal, and a very large portion (perhaps 40%) in sub-Saharan Africa, there is no way mortality can be anywhere near 10%. The reports I've read of outbreaks in sub-Saharan Africa suggest a mortality of more like 1%, sometimes less.--Solomonfromfinland (talk) 10:06, 5 May 2013 (UTC)

Thank you for pointing this out. I've reworded it to what the source actually states. ComfyKem (talk) 13:47, 5 May 2013 (UTC)

Citations[edit]

I recently saw two sections where it said, "This section does not cite any references or sources." However, I no longer see this, or any other notice indicating lack of proper citations. Did these sections get removed, or were citations added?--Solomonfromfinland (talk) 10:12, 5 May 2013 (UTC)

Hello. The two sections in question that had no references were titled Diagnosis and Genotypes. I have since provided sources for the diagnosis section, and the genotype section has been moved to the article Measles virus. ComfyKem (talk) 12:15, 5 May 2013 (UTC)

Fatality rate confused with Mortality rate[edit]

It states the fatality rate as x in 1000, this is the mortality rate. Because the article confuses these two types of rates the figures given need reviewing. — Preceding unsigned comment added by 86.152.113.198 (talk) 14:34, 12 May 2013 (UTC)

Move complications[edit]

The subsection “Complications” should probably be moved from “Signs and symptoms” to “Prognosis”. Do you agree?--Solomonfromfinland (talk) 07:30, 15 May 2013 (UTC)

I do agree, but the current parts of Prognosis would have to be rewritten so as not to provide repetitive information. The "risk factors for complications" in the Cause section may need to be moved as well. ComfyKem (talk) 08:58, 16 May 2013 (UTC)

105[edit]

Under “Prognosis”, it says, “The vast majority of patients survive measles, though in some cases complications may occur, which may include bronchitis, and – in about 1 in 100,000 cases – panencephalitis, which is usually fatal.” (Citation deleted.) I wrote the 100,000 as 105, but it was reverted. Do you think the 105 form should be restored? I prefer 105 because it is more concise; I don't believe in using 6 or 7 characters to write what can be written in 3.--Solomonfromfinland (talk) 05:22, 22 November 2013 (UTC)

Disease that can be eliminated[edit]

Measles is a disease that can be eliminated and even eradicated. There are a few criteria that it fulfils to be entitled for elimination. It does not have any reservoir. There are a few other reasons. I think the list needs to be incorporated into this article. DiptanshuTalk 08:04, 21 January 2014 (UTC)
