    EuroFlu - Weekly Electronic Bulletin Week 17 : 26/04/2010-02/05/2010 - 07 May 2010, Issue N 357

    Influenza activity in Europe approaching out-of-season levels
    • This report is based on data received from 39 of the 53 Member States in the WHO European Region.
    • Most countries reported a low intensity of influenza activity.
    • 3.8% of specimens collected from sentinel sources tested positive for influenza.
    • A total of 4862 deaths associated with laboratory-confirmed pandemic A(H1N1) 2009 has been reported in the Region since April 2009.

    Current situation: week 17/2010

    Clinical consultation rates for influenza-like illness (ILI) and acute respiratory infection (ARI) remain at low levels throughout the Region. Most countries (N = 31) did not report a dominant virus, indicating limited influenza activity overall.


    Virological update: week 17/2010

    Sentinel physicians collected 263 respiratory specimens, of which 10 (3.8%) tested positive for influenza virus; 3 were unsubtyped influenza A and 7 were influenza B. Specimens from non-sentinel sources yielded 155 influenza detections: 21 type A (2 pandemic A(H1), 6 A(H3), 3 A(H1) and 10 A unsubtyped) and 134 influenza B.

    From week 40/2009 to week 17/2010, 166 169 influenza virus detections have been reported: 164 317 were influenza A (98.9%) and 1852 (1.1%) were influenza B. Of the influenza A viruses, 150 267 (91.4%) were subtyped, with 148 521 being pandemic A(H1), 1086 A(H1), and 660 A(H3).

    Based on the reported antigenic characterization of 3436 influenza viruses from week 40/2009 to week 17/2010, 3392 were A(H1) pandemic A/California/7/2009 (H1N1)-like; 2 were A(H1) A/Brisbane/59/2007 (H1N1)-like; 8 were A(H3) A/ Brisbane/10/2007 (H3N2)-like; 17 were A(H3) A/Perth/16/2009 (H3N2)-like; 5 were B/Florida/4/2006-like (B/Yamagata/16/88 lineage) and 12 were B/Brisbane/60/2008-like (B/Victoria/2/87 lineage).

    Genetic characterizations have been reported for 1262 isolates: 1223 belonged to the A/California/7/2009 A(H1N1) pandemic group; 1 belonged to the A/Brisbane/10/2007 (H3N2) group; 13 to the A/Perth/16/2009 (H3N2) group; 5 to the A/Victoria/208/2009 (H3N2) group; 2 to the B/Bangladesh/3333/2007 (Yamagata) and 18 to the B/England/393/2008 (Victoria) lineages.


    Comment

    Influenza activity is at a low level throughout the European Region. The current influenza positivity rate for the Region is low (3.8%), and in week 17/2010 the number of sentinel and non-sentinel influenza B detections (141, 85.5%) exceeded that of influenza A (24, 14.5%). The viruses characterized to date are similar to those recommended as components of influenza vaccines for use in the 20102011 northern hemisphere influenza season.

            Influenza activity in Europe is at out-of-season levels

            During weeks 2239/2010, the EuroFlu bulletin will be published biweekly and will report available data.
            • This is the first summer report, based on data reported in week 23/2010 by 34 Member States in the WHO European Region.
            • 3 out of 112 of specimens collected from sentinel sources tested positive for influenza, with 1 of these positive for pandemic A(H1).

            Current situation: week 23/2010

            Clinical consultation rates for influenza-like illness (ILI) and acute respiratory infection (ARI) have reached low levels throughout the Region. 24 countries reported assessments of influenza activity based on qualitative indicators: all reported low intensity of influenza activity, with 8 reporting sporadic activity.


            Virological update: week 23/2010

            Sentinel physicians collected 112 respiratory specimens, of which 3 (2.7%) tested positive for influenza virus; 1 was pandemic A(H1) and 2 were influenza B. Specimens from non-sentinel sources yielded 26 influenza detections: 8 type A (5 pandemic A(H1), and 3 A unsubtyped) and 18 influenza B.


            Cumulative virological data: from week 22/2010

            From week 22/2010 to week 23/2010, 75 influenza virus detections were reported: 19 were influenza A (25.3%) and 56 (74.7%) were influenza B. Of the influenza A viruses, 12 (63.2%) were subtyped, with 7 being pandemic A(H1) and 5 A(H1).


            Comment

            Influenza activity is at out-of-season levels throughout the European Region. The current influenza positivity rate for the Region is low (2.7%) and, while the total number of influenza detections was low in week 23/2010, the number of sentinel and non-sentinel influenza B detections (20: 69.0%) exceeded that of influenza A (9: 31.1%). The viruses characterized to date are similar to those recommended as components of influenza vaccines for use in the 20102011 northern hemisphere influenza season.

              Clinical consultation rates for influenza-like illness (ILI) and acute respiratory infection (ARI) have reached low levels throughout the Region. 31 countries reported low levels of clinical incidence and, since there were no confirmed cases from sentinel sources, it can be concluded that there is no recognizable influenza activity.


              Virological update: week 25/2010

              Sentinel physicians collected 123 respiratory specimens, none of which tested positive for influenza virus. Specimens from non-sentinel sources yielded 20 influenza detections: 4 type A (3 pandemic A(H1), and 1 A unsubtyped) and 16 influenza B.


              Cumulative virological data from week 22/2010

              From week 22/2010 to week 25/2010, 95 influenza virus detections were reported: 23 were influenza A (24.0%) and 72 (76.0%) were influenza B. Of the influenza A viruses, 15 (65.2%) were subtyped, with 9 being pandemic A(H1) and 6 A(H1).


              Comment

              Influenza activity is at very low levels throughout the European Region. Virological surveillance at sentinel sites yielded no influenza-positive specimens. In week 25, the number of non-sentinel influenza B detections (16: 80.0%) exceeded that of influenza A (4: 20.0%). The viruses characterized to date are similar to those recommended as components of influenza vaccines for use in the 20102011 northern hemisphere influenza season.


              Further information

              The EuroFlu bulletin describes and comments on influenza activity in the 53 countries in the WHO European Region. Further information can be obtained from the WHO/Europe and WHO headquarters web sites.

                Very little influenza activity in the WHO European Region

                During weeks 2239/2010, the EuroFlu bulletin will be published biweekly, and report available data.
                • This issue is based on data reported in week 27/2010 by 26 Member States in the WHO European Region.
                • It also includes information on current influenza activity in the temperate regions of the southern hemisphere.
                • In the WHO European Region, 1 out of 24 of specimens collected from sentinel sources tested positive for influenza.

                Current situation: week 27/2010

                Clinical consultation rates for influenza-like illness (ILI) and acute respiratory infection (ARI) have reached low levels throughout the WHO European Region. 28 countries reported low levels of clinical incidence. There was only one virologically confirmed influenza case from sentinel sources and there is no significant influenza activity in the Region.


                Virological update: week 27/2010

                Sentinel physicians collected 24 respiratory specimens, of which 1 (4.2%) tested positive for influenza virus B. Specimens from non-sentinel sources yielded 3 detections of influenza A unsubtyped viruses.


                Cumulative virological data from week 22/2010

                From week 22/2010 to week 27/2010, 99 influenza virus detections were reported: 26 were influenza A (26.3%) and 73 (73.7%) were influenza B. Of the influenza A viruses, 15 (57.7%) were subtyped, with 9 being pandemic A(H1) and 6 seasonal A(H1).


                Comment

                Influenza activity is at very low levels throughout the European Region. Virological surveillance at sentinel sites yielded only one influenza-positive specimen. The viruses characterized to date are similar to those recommended as components of influenza vaccines for use in the 20102011 northern hemisphere influenza season.


                Influenza activity in the temperate regions of the southern hemisphere

                Monitoring influenza virus circulation in the temperate regions of the southern hemisphere, where it is currently winter, can inform planning in advance of the influenza season in the northern hemisphere. The following section provides a brief update of the current situation in the southern hemisphere where detections of pandemic (H1N1) 2009 influenza, influenza A(H3N2) and influenza B are being reported amid the circulation of other respiratory viruses.
                • Australia, as of 15 July 2010
                  • ILI presentations in Western Australia have increased gradually over the past three weeks. Of nine influenza viruses detected from sentinel and non-sentinel surveillance systems eight were identified as pandemic (H1N1) 2009 viruses and one as an influenza A(H3N2) virus. Click here for further information.
                  • In the State of Victoria most viruses detected through routine testing this week were picornavirus and respiratory syncytial viruses (RSV), with one pandemic (H1N1) 2009. Of the 17 influenza viruses detected so far this year, 9 have been pandemic (H1N1) 2009, 3 have been influenza A(H3N2) and 5 have been untyped (not pandemic (H1N1) 2009).

                        Influenza activity is at a very low level throughout the European Region. The viruses characterized to date are similar to those recommended as components of influenza vaccines for use in the 20102011 northern hemisphere influenza season.


                        Influenza activity in the temperate regions of the southern hemisphere

                        Monitoring influenza virus circulation in the temperate regions of the southern hemisphere, where it is currently winter, can inform planning in advance of the influenza season in the northern hemisphere. The following section provides a brief update of the current situation in selected countries in the southern hemisphere, where detections of pandemic (H1N1) 2009 influenza, influenza A(H3N2) and influenza B are reported amid the circulation of other respiratory viruses.
                        • Australia, as of 15 August 2010
                          • The number of laboratory-confirmed influenza cases in Western Australia continues to increase. In the week ending 15 August 2010, 52 influenza viruses were detected from sentinel and non-sentinel surveillance systems, of which 20 were pandemic (H1N1) 2009 virus, 22 type B virus, 2 A(H3N2) viruses, and 8 influenza A type unknown.
                          • Further information is available from Virus WAtch .
                          • ILI presentations in the State of Victoria increased slightly and ILI activity is currently above baseline levels. In the week ending 15 August 2010 most respiratory viruses detected were picornaviruses; only 4 influenza viruses (3 pandemic (H1N1) 2009 and 1 A(H3N2)) were detected. Of the 41 influenza viruses reported by sentinel and non-sentinel surveillance systems this year, 23 have been identified as pandemic A(H1N1) 2009 viruses, 12 as A(H3N2) viruses, and 5 as influenza A subtype unknown.
                          • See The 2010 Victorian influenza vaccine effectiveness audit report for further information.
                        • South America, as of 23 August 2010
                          • In South America, the intensity of acute respiratory disease activity is low to moderate. The trends in acute respiratory disease are decreasing in Argentina, and remain unchanged in Brazil and Chile. In Argentina and Chile respiratory syncytial virus (RSV) remains predominant.
                          • Further information is available from the Pan American Health Organization (PAHO).
                        • South Africa, as of 1 August 2010
                          • Of the 1100 ILI specimens collected from sentinel care providers in South Africa, 117 have tested positive for influenza B viruses, 124 for influenza A(H3N2) viruses,14 for pandemic A(H1N1) 2009 viruses and 2 for influenza A unsubtyped. Among 2490 hospitalized cases of severe acute respiratory illness (SARI), 66 had tested positive for influenza B and 31 for influenza A(H3N2).
                          • Further information is available from the National Institute for Communicable Diseases (NICD) in South Africa.

                          Very sporadic influenza detection in the WHO European Region

                          During weeks 2239/2010, the EuroFlu bulletin is published biweekly, reporting available data.

                          • This issue is based on data reported in week 35/2010 by 29 Member States in the WHO European Region.
                          • It also includes information on current influenza activity in the temperate regions of the southern hemisphere.
                          • On 10 August 2010, the WHO Director-General declared an end to the H1N1 influenza pandemic.
                          • In the WHO European Region, 1 of 65 specimens collected from sentinel sources tested positive for influenza B virus during week 35/2010.
                          • In the southern hemisphere, the influenza viruses detected are represented by a combination of pandemic (H1N1) 2009, influenza A(H3N2) and influenza B.

                          Current situation: week 35/2010

                          Clinical consultation rates for influenza-like illness (ILI) and acute respiratory infection (ARI) are at low levels throughout the WHO European Region. Only the Netherlands reported laboratory-confirmed influenza in sentinel practices, indicating insignificant influenza activity in the Region.


                          Virological update: week 35/2010

                          Sentinel physicians collected 65 respiratory specimens, 1 of which tested positive for influenza B virus. Out of 1029 specimens collected from non-sentinel sources, 5 tested positive: 5 type A viruses (1 A(H3), 1 A(H1), 1 pandemic A(H1), 2 unsubtyped).


                          Cumulative virological data from week 22/2010

                          From week 22/2010 to week 35/2010, 159 influenza virus detections in sentinel specimens were reported: 31 were influenza A (19.5%) and 128 (80.5%) were influenza B. Of the influenza A viruses, 13 (42.0%) were subtyped, with 5 being pandemic A(H1) and 8 seasonal A(H3N2).


                          Comment

                          Influenza activity is at a very low level throughout the European Region. The viruses characterized to date are similar to those recommended as components of influenza vaccines for use in the 20102011 northern hemisphere influenza season.

                            EuroFlu - Weekly Electronic Bulletin - Week 37 : 13/09/2010-19/09/2010 - 24 September 2010, Issue N 369

                            Very limited, sporadic influenza detections in the WHO European Region

                            During weeks 22-39/2010, the EuroFlu bulletin is published biweekly, reporting available data.
                            • This issue is based on data reported in week 37/2010 by 25 Member States in the WHO European Region.
                            • It also includes information on current influenza activity in the temperate regions of the southern hemisphere.
                            • In the WHO European Region, 2 of 94 specimens collected from sentinel sources tested positive for influenza during week 37/2010.
                            • In the southern hemisphere, the influenza viruses detected are represented by a combination of pandemic (H1N1) 2009, influenza A(H3N2) and influenza B.

                            Current situation: week 37/2010

                            Clinical consultation rates for influenza-like illness (ILI) and acute respiratory infection (ARI) are at low levels throughout the WHO European Region. Only the Russian Federation and the United Kingdom have reported laboratory-confirmed influenza in sentinel practices in recent weeks, indicating insignificant influenza activity in the Region.


                            Virological update: week 37/2010

                            Sentinel physicians collected 94 respiratory specimens, 2 of which tested positive for influenza with 1 being pandemic A(H1N1) and the other influenza B virus. Out of 669 specimens collected from non-sentinel sources, 1 influenza A virus (not subtyped) was detected.


                            Cumulative virological data from week 22/2010

                            From week 22/2010 to week 37/2010, 161 influenza virus detections in sentinel specimens were reported: 32 were influenza A (19.9%) and 129 (80.1%) were influenza B. Of the influenza A viruses, 14 (43.8%) were subtyped, with 6 being pandemic A(H1) and 8 seasonal A(H3N2).


                            Comment

                            Influenza activity is at a very low level throughout the European Region. The viruses characterized to date are similar to those recommended as components of influenza vaccines for use in the 20102011 northern hemisphere influenza season.


                            Influenza activity in the temperate regions of the southern hemisphere

                            Monitoring influenza virus circulation in the temperate regions of the southern hemisphere, where it is currently winter, can inform planning in advance of the influenza season in the northern hemisphere. The following is a brief update of the current situation in selected countries of the southern hemisphere, where detections of pandemic (H1N1) 2009 influenza, influenza A(H3N2) and influenza B are reported amid circulation of other respiratory viruses.
                            • The most commonly identified influenza virus in Australia is pandemic (H1N1) 2009, though influenza type B is also being detected (report of 12 September 2010). Further information is available at Virus WAtch.
                            • Chile has reported increasing respiratory disease activity for the last two weeks, which is later than usual (report of 10 September 2010). Pandemic (H1N1) 2009 has been the most commonly detected influenza virus so far this season, but in recent weeks there has been a shift towards influenza type B and influenza A(H3N2). Further information is available from the Pan American Health Organization (PAHO) and WHO headquarters.
                            • In South Africa, influenza type B has been the most commonly detected influenza virus throughout this winter season, though in recent weeks the proportion of pandemic (H1N1) 2009 virus has increased and a small and decreasing number of influenza A(H3N2) detections continues. For further information, see the report of 16 September on the National Institute for Communicable Diseases web site.
