Euro Surveill. Surveillance of Hospitalisations for 2009 Pandemic Influenza A(H1N1) in the Netherlands, 5 June – 31 December 2009

Eurosurveillance, Volume 15, Issue 2, 14 January 2010

"clinical and epidemiological characteristics of patients hospitalised in the Netherlands for the 2009 pandemic influenza A(H1N1)"

Several interesting observations can be made:

- Obesity did not seem to be a riskfactor, however, no systematic data was collected on length and weight of the hospitalised patients not reported to be obese, which may have resulted in underreporting as obesity is likely to have been a subjective assessment of the attending physician.

- 44,2 % of the hospitalised patients did not have an underlying disease

- 9,8 % of the deaths did not have an underlying disease

- Asthma was the most common underlying condition, followed by other chronic lung disease and cardiovascular disease

- The median age of non-ICU hospitalised patients was 17 years

- For patients admitted to an ICU the median age was 42 years

- For patients who died the median age was 52 years

- Incidence of non-ICU hospitalisations peaked in the group of 0-4 year-olds and thereafter declined with age.

- Incidence of ICU admissions and deaths, however, showed a second peak in the group of 55-64 year-olds

- Of the non-ICU hospitalised patients 29.5% (508/1,722) had pneumonia

- Among the patients who were admitted to an ICU, 74.3% (153/206) had pneumonia and 63.3% (126/199) needed mechanical ventilation.

- Pneumonia was reported for 31 of 46 fatal cases for whom this information was available and 21 of 49 patients who died had received mechanical ventilation.

Re: Netherlands - (A) H1N1 - Hospitalisations 2,202 - Deaths 59

RIVM April 1st (week 12) is reporting 59 fatalities, but the ECDC is reporting 61.
http://www.rivm.nl/cib/themas/nieuwe-influenza/stand-van-zaken.jsp
http://ecdc.europa.eu/en/publicatio...SN_Weekly_Influenza_Surveillance_Overview.pdf (page 11)

Edit: On second view, the RIVM is dated March 25th, but both are called week 12.

Today RIVM updated their website. announcing the 60th fatality.

I assume #61 will be reported next week in the weekly update on friday.
