2009 pandemic influenza A (H1N1) ? December 22, 2009 Update
Main developments in the past
This report is based on official information provided by national public health websites or through other of communication channels. Reported number of confirmed and intensive care, by country, as of 22 December on the number of confirmed fatal cases for the world and Europe is presented in Table 2.

The ECDC has re-designed its 2009 influenza A (H1N1) pandemic webpage.
The new design takes into account user feedback and has been implemented to facilitate easier navigation of the page and smooth access to the news, surveillance, guidance and scientific advice ?documents that the ECDC produces to help the member states and the international community to deal with the pandemic. It also features direct links to current articles on the pandemic in Eurosurveillance.
Access to the pandemic webpage is through the same main webpage banner link as before and can be easily found from the ECDC main page: LINK

Epidemiologic update
All 27 EU and 4 EFTA countries are reporting cases of pandemic (H1N1) 2009 influenza. A total of 1 671 deaths have been reported since April 2009 (Table 2). Since week 41 the numbers of deaths each has shown a steady increase almost doubling every fortnight over the last six weeks. While the most deaths have to date been in Western Europe there are increasing numbers of deaths being reported from Central and Eastern Europe. The reported cumulative fatal pandemic (H1N1) cases in the world have now passed 10 000 cases (Table 2). However, because of lack of laboratory confirmation and underreporting among other factors, this is likely to be a gross underestimation of the true number of fatalities associated with the pandemic. Available updates on hospital admissions, per Member State, can be found in Table 1.

Updates from US and Canada
From U.S. Centers for Disease Control and Prevention (CDC) weekly influenza surveillance report:
- During the week of December 6-12, 2009, influenza activity decreased over the previous week across all key indicators.
- Most indicators, however, remain higher than normal for this time of year.
- Visits to doctors for influenza-like illness (ILI) nationally decreased slightly this week over last week. This is the seventh consecutive week of national decreases in ILI after four consecutive weeks of sharp increases.
- While ILI has declined, visits to doctors for influenza-like illness remain slightly elevated nationally.
- Influenza hospitalizations and hospitalization rates decreased in all age groups.
- The proportion of deaths attributed to pneumonia and influenza (P&I) based on the 122 Cities Report decreased over the previous week, but remains elevated for this time of year.
- This proportion has been higher than expected for eleven consecutive weeks.
- In addition, 9 flu-related pediatric deaths were reported this week: 8 of these deaths were associated with laboratory confirmed 2009 H1N1, and one was associated with an influenza A virus that was not subtyped.
- Since April 2009, CDC has received reports of 276 laboratory-confirmed pediatric deaths: 232 due to 2009 H1N1, 42 pediatric deaths that were laboratory confirmed as influenza, but the flu virus subtype was not determined, and two pediatric deaths that were associated with seasonal influenza viruses.
- Laboratory-confirmed deaths are thought to represent an undercount of the actual number. CDC has provided estimates about the number of 2009 H1N1 cases and related hospitalizations and deaths (see ECDC Daily update 15th December, 2009 and CDC at LINK).
- 391 (6.9%) specimens tested by U.S. World Health Organization (WHO) and National Respiratory and Enteric Virus Surveillance System (NREVSS) collaborating laboratories and reported to CDC/Influenza Division were positive for influenza.
- Over 99% of all subtyped influenza A viruses being reported to CDC were 2009 influenza A (H1N1) viruses.
- The proportion of deaths attributed to pneumonia and influenza (P&I) was above the epidemic threshold for the eleventh consecutive week.
- Nine influenza-associated pediatric deaths were reported. Eight of these deaths were associated with 2009 influenza A (H1N1) virus infection and one was associated with an influenza A virus for which the subtype was undetermined.
- The proportion of outpatient visits for influenza-like illness (ILI) was 2.6% which is above the national baseline of 2.3%. Five of the 10 regions reported ILI at or above region-specific baseline levels. Regions 3, 6, 7, 8 and 10 reported ILI below their region specific baselines.
- Eleven states reported geographically widespread influenza activity, 20 states reported regional influenza activity, the District of Columbia, Puerto Rico, and 11 states reported local influenza activity, the U.S. Virgin Islands and eight states reported sporadic influenza activity, and Guam reported no influenza activity.
- For more information:
From the Public Health Agency of Canada:
- On week 49 (December 6-12, 2009), the overall influenza activity continued to decline for the fourth consecutive week in Canada.
- The ILI consultation rate was below the expected range for this time of the year and only 6.6% of the specimens tested were positive for influenza. The Pandemic (H1N1) 2009 strain still accounted for nearly 100% of the positive influenza A subtyped specimens this week.
- The number of hospitalized cases (159 vs. 307), ICU admissions (40 vs. 83) and deaths (21 vs. 33) reported this week are about half of those reported last week. Among reporting provinces and territories (PTs) this week, hospitalized cases occurred in only six provinces (BC, AB, SK, ON, QC & NS). Deaths reported this week were also from the same five provinces except MB (BC, AB, SK, MB, ON & QC).
- From August 30 to December 12, 2009, a total of 6,779 hospitalized cases including 1,081 (15.9%) cases admitted to an intensive care unit (ICU) as well as 313 (4.6%) deaths had been reported.
