All of the links I tried in the reference section gave me 404 errors. The first two, to Dorlands Medical Dictionary, go to the Wayback Machine, but the page is not found. The page the wayback machine references in on MerckSource. The link to the article "Quantifying Diseases in populations" goes to the BMJ Group site but it also says page not found.
So references 1, 2 and 4 don't exist (and 3 and 5 don't have have an online source).
Where no time interval is given "The incidence is 3 per 10,000" does this mean per annum?
- I believe that is correct--Bakerstmd 15:58, 27 May 2007 (UTC)
Is the present definition of this epidemiological term really correct? From what I know epidemiological incidence should be defined as: (The number of cases in a population during a certain period of time) divided with (The sum of time for all individuals where these individuals are at risk to develop the disease). My point is that Incidence is distinct from Cumulative incidence. /22.214.171.124 13:07, 6 January 2007 (UTC)
- You're right, the article was quite bogus. I fixed it just now. Eubulides 07:28, 28 May 2007 (UTC)
Prevalence = Incidence x Duration ?
The article states that:
- Prevalence is approximately the multiple of disease incidence and average disease duration , so Prevalence = Incidence x Duration
Is this actually correct? It doesn't consider deaths (or even recoveries and moving). For example, if a hypothetical disease kills you instantly, its prevalence would tend to zero, even if incidence is high. As a matter of fact, isn't Incidence x Duration called cumulative incidence?
