Re: Summary of Arizona Dept. of Health

Thanks High Risk. The bolding you've done could be a bit misleading.


0 lab-confirmed influenza-associated pediatric deaths were reported in the past week.

12 have been reported this season. 7 of the 12 were confirmed to be 2009 H1N1 influenza virus.

Re: Summary of Arizona Dept. of Health

Good report High Risk! Interesting to see the difference between seasons.

15 pneumonia and influenza deaths were identified from death certificates in the past week; 813 pneumonia and influenza deaths have been identified in the 2008-2009 influenza season; 1,083 pneumonia and influenza deaths were identified for the same time period during the 2007-2008 influenza season

I think we can take for granted the fact that any further pneumonia ili deaths will be A/H1N1 though - from your report

518 laboratory-confirmed cases of influenza were reported in the past week, a 41% increase compared to the prior week
•
100% of subtyped influenza viruses at the Arizona State Laboratory during the previous week were 2009 H1N1 influenza virus

Do you know if they are going to compile a list of deaths by county?

Re: Summary of Arizona Dept. of Health

Thanks High Risk.

 

[JimO]

Re: Summary of Arizona Dept. of Health

Yes, thanks.

Nine deaths in one week! That's just over 25% of the deaths. That increased their population-based death rate by ~1.5 deaths per million to 6.0.

what's "school enrollment" ?

Re: Summary of Arizona Dept. of Health

what's "school enrollment" ?

You can use Google for words as well as numbers you know

http://www.merriam-webster.com/dictionary/enroll

Main Entry: en·roll
Variant(s): also en·rol \in-ˈrōl, en-\
Function: verb
Inflected Form(s): en·rolled; en·roll·ing
Etymology: Middle English, from Anglo-French enrouler, from en- + rolle roll, register
Date: 14th century

transitive verb

1 : to insert, register, or enter in a list, catalog, or roll - the school enrolls about 800 pupils
2 : to prepare a final perfect copy of (a bill passed by a legislature) in written or printed form
3 : to roll or wrap up in

transitive verb : to enroll oneself or cause oneself to be enrolled <we enrolled in the history course

In other words just the total registered at a school (i.e. everyone at school).

Re: Summary of Arizona Dept. of Health

so, this is the number out of 100000 random
pupils from Arizona schools who reported with ILI in that week ?

Re: Summary of Arizona Dept. of Health

so, this is the number out of 100000 random
pupils from Arizona schools who reported with ILI in that week ?

Yes it is. Or hopefully more specifically the number per 100,000 absent from school with ILI reported.

Re: Summary of Arizona Dept. of Health

{Sidelight --- not azdhs}

From 2008 numbers, (as far as I can tell, US census based), total student population in Arizona public and charter schools comes in at very roughly 1,196,455 students.

Additionally, counting five of the major universities and colleges (so a few of these would be older than age 24), the 2009 numbers are about 120,020.

Glossary of Key Terms:
2009-2010 Influenza Season – The season is defined by surveillance weeks. The first day of the 2009-2010 influenza season was October 4th, 2009, or week 40 and the 2009-2010 surveillance season will continue through October 2nd, 2010, or week 39.
Widespread Activity – Increased influenza-like illness (ILI) and/or institutional outbreaks (ILI or laboratory-confirmed) in at least half of Arizona’s defined regions AND recent (within the previous three weeks) laboratory-confirmed influenza in the state.
Pneumonia and Influenza Mortality – Many influenza-related deaths are due to complications of influenza infection, including pneumonia, and influenza is infrequently listed as the cause of death on death certificates. Surveillance from death certificates often uses the category of “pneumonia and influenza” as an indicator, although not all pneumonias are associated with influenza. See the CDC website for more information http://www.cdc.gov/flu/about/disease/us_flu-related_deaths.htm.
Hospitalization – A hospitalization, for purposes of 2009 H1N1 influenza investigations, is defined as a laboratory-confirmed 2009 H1N1 influenza case who has been admitted to the hospital for at least 24 hours.
