:James, incidence and prevalence are <u>proportions</u>. Prevalence is those who are already infected at a defined time per total population. Incidence is those who acquire an infection during a defined timescale per total population. They are not simple totals. That's why they are given as a rate.

Phases 1-5 of chronic infection graph

I have been preparing some slides for a talk about hepatitis B. As part of this I wanted a graphical slide that detailed phases 1-5 of chronic infection and associated serology consistent with the new EASL guidelines. I couldn't find one that I liked and so I ended up making one, which is here:

Do others think that this would be a useful addition to the Hepatitis B page or not?

Thanks

User:Gwilz which EASL guideline is this based on? Can you provide a url? Doc James (talk · contribs · email) 11:47, 31 January 2018 (UTC)[reply]

Simplification

User:Graham Beards wondering your thoughts on?

"Hepatitis B incidence rate in 2017" -> "New cases of hepatitis B in 2017"

James, incidence and prevalence are proportions. Prevalence is those who are already infected at a defined time per total population. Incidence is those who acquire an infection during a defined timescale per total population. They are not simple totals. That's why they are given as a rate. I think it is best to link the terms rather than attempt to simplify them. Graham Beards (talk) 20:47, 20 April 2020 (UTC)[reply]
Yes incidence in this case is "new cases per 100,000 people in 2017" and prevalence is current cases per X number of people in 2005. It is the percentage of the population affected. Doc James (talk · contribs · email) 22:36, 20 April 2020 (UTC)[reply]

Updated image

Prevalence of hepatitis B virus infection[1]

Any concerns with replacing the prior prevalence image with this one? This gives numbers for prevalence rather than just high, intermediate, low. Doc James (talk · contribs · email) 22:42, 20 April 2020 (UTC)[reply]
