    Influenza Report, Week 40 (1/10 - 7/10), 2012
    Report on the current flu situation

    Influenza in Sweden
    Influenza activity is still low in Sweden for 40 weeks reported Västra Götaland a case of seasonal influenza A (H3N2) who were traveling abroad and only a few cases of patients with influenza-like illness reported by sentinel surveillance from across the country. By sentinel sampling has 5 samples received but none contained the virus.

    During the summer, sporadic cases of influenza reported from laboratories in Stockholm, Scania, Västra Götaland, and Örebro. The cases reported during the summer weeks are probably people who become infected during travel abroad. During week 37, two cases of influenza B from Stockholm and Västra Götaland and one case of influenza A (H1N1) pdm09 from Stockholm. During week 39 reported a case of seasonal influenza A (H3N2) from Västra Götaland.

      Influenza in Sweden
      Four cases of laboratory confirmed seasonal influenza A were reported during week 42 and after were also reported for week 41. They had been diagnosed in Kronberg, Jamtland (2 cases), Stockholm and Västra Götaland. Two people were infected abroad, but the case in Kronoberg of the cases in Jämtland has not been infected abroad. During week 42, only a few patients with flu-like symptoms reported in the sentinel system. None of the 28 control samples that come to SMI have included flu.

      All in all, suggests that flu season is under way in Sweden, both in the north and south, but not yet received wide circulation. Influenza Vaccination in the county has just started and right now, at the start of the season but before the flu become widespread, it is a very appropriate time to get vaccinated if you need protection against influenza. For more information, see the Board's recommendations on who should get vaccinated against the flu .

      Besides influenza stray cases of respiratory syncytial virus (RSV) has been reported from different parts of the country (see RSV report for week 42 ). Although RSV season appears to have begun.

        Influenza in Sweden
        Week 43 reported one laboratory-confirmed influenza cases in Sweden. The case was diagnosed in Stockholm and subtype influenza A (H1N1) pdm09.

        The sentinel surveillance is still low activity with only isolated cases of influenza-like illness (ILI) reported. All ILS cases have been reported so far has been between 15-64 years old. Thirty-seven samples were collected within the sentinel surveillance, but all have been negative for influenza.

        The number of calls to 1177 with questions about fever in children have previously been shown to be a good indicator of flu activity. The graph of the number of calls increased slightly in recent weeks, but has now leveled off. Although Web Search, which analyze searches made on Vårdguiden.se, show low activity.

        RSV has also this week been diagnosed at various laboratories in Sweden, but we see no increase compared with last week (see the weekly RSV reports ).

          Influenza Report, Week 44 (29/10 - 4/11), 2012

          Editor: Hélène Englund , 08-457 23 54

          Influenza in Sweden
          During week 44, the number of reported flu cases compared to the previous week, but we have no indication that the spread took off in earnest. A total of five laboratory-confirmed influenza cases were reported, three seasonal influenza A and influenza B. The two cases reported from Stockholm, Jonkoping and Gothenburg. (Due to past problems with the transfer of data within the voluntary reporting, the number of laboratory confirmed cases from previous weeks in Table 2 corrected in this report., The total number of cases reported since monitoring start week 40 in 2012 are now 12 of them.)

          Number of patients who applied with flu-like symptoms, and reported in the sentinel system, has also increased but are still only three countries that have reported cases. The sentinel samples received 41 samples of which one was positive for influenza A (H1N1) pdm09 ("swine flu") from Stockholm. Within our monitoring sampling in children and infection clinics received 12 samples. Although there was a sample positive for influenza A (H1N1) pdm09, from Jönköping. The number of web searches on flu and telephone inquiries for 1177 is at a normal level for the season.

            Influenza Report, Week 45 (5/11 - 11/11), 2012
            Report on the current flu situation

            Editor: Hélène Englund , 08-457 23 54

            Influenza in Sweden
            Week 45 reported nine laboratory confirmed cases in Sweden, three each of influenza A, influenza B and influenza A (H1N1) pdm09 (see Table 1 and Figure 1 below).

            The number of patients who visited sentinel called last week with flu-like illness (ILI) , as well as the number of samples that are submitted for analysis, declined slightly. This may be a "fall holiday" effect. None of the 34 analyzed sentinel specimens were positive for influenza. Nor any of the six samples taken at the child and infection clinics and analyzed at the SMI was positive.

            The number of web searches on flu and telephone inquiries for 1177 remains at a normal level for the season.

              Report on the current flu situation

              Editor: Hélène Englund

              Influenza in Sweden
              Week 46 reported 11 laboratory-confirmed influenza cases: six seasonal influenza A, four seasonal influenza B and influenza A (H1N1) pdm09.

              Participating sentinel units reported 14 visits by patients with influenza-like illness (ILS). This is the same magnitude as week 44. None of the 39 samples taken on the ILS patients in sentinel surveillance were positive for influenza, suggesting that there still are other viruses that cause respiratory symptoms. (See last week's text of circulating respiratory viruses.) Nor anything out of the seven samples from the child and infection clinics analyzed at SMI were positive for influenza.

              The number of calls to 1177 with questions concerning fever in children, the symptom that proved to be the best indicator of flu, was of the same magnitude as the corresponding period last year. (See also In-depth stats below.)

                  Report on the current flu situation

                  Editor: Hélène Englund

                  Influenza in Sweden
                  Week 48 reported 14 laboratory confirmed cases of influenza from different parts of the country (see Table 2 ). One of influenza A (H1N1) pdm09-cases were reported from an intensive care unit.

                  Only a few patients with influenza-like illness reported by sentinel surveillance, and none of the samples taken thus were positive for influenza. Nor any of the samples from the child and infection clinics were positive.

                  Inquiries to the 1177 (see chart ) regarding fever in children and syndromic surveillance Web Search shows a rising trend, but do not indicate any widespread flu activity. The past few weeks increase in phone calls to 1177 for cough in children may be linked to the increase in RSV and whooping cough which is now observed in the country.

                    Editor: Hélène Englund

                    Influenza in Sweden
                    During week 49, the number of laboratory-confirmed influenza cases for the second week in a row, from 16 cases, weeks 48 to 23 cases. This increase is normal for the season, and if nothing exceptional happens, the peak occurring in February.

                    Still lost both seasonal influenza A and B and influenza A (H1N1) pdm09. Thorough analyzes suggest that the circulating strains similar to vaccine strains (see the depth characterization of virus ).

                    Sentinel reporting shows no increase in influenza-like illness, but during week 49 influenza virus was detected in two samples taken in sentinel surveillance.

                    Web Search and Flu Koll speaks for normal flu activity for the season, and the number of calls to 1177 (see report ).

                      Report on the current flu situation

                      Editor: Hélène Englund

                      Influenza in Sweden
                      For week 50 shows all monitoring systems for normal seasonal influenza activity and no significant increase in flu expected over the Christmas holidays. During week 50, the number of laboratory-confirmed influenza cases from the total 29 cases, 49 weeks for a total of 36 cases, week 50. Most cases were reported from metropolitan counties, but cases were also reported from Uppsala, Södermanland, Blekinge, Halland, Västmanland, Värmland, Dalarna, and Västerbotten ( see map ). Most were seasonal influenza A (24 cases), while 6 cases each of influenza B and influenza A (H1N1) pdm09 reported. Sentinel reporting shows no increase in influenza-like illness, but during week 50 influenza virus was detected in four samples taken in sentinel surveillance. The proportion of positive samples received thus rose for the second week in a row.

                      Calls to 1177 which is about fever among children as well as fever and cough among adults is increasing, but the increase is normal for the season. Infections always increases during december but the morbidity of respiratory infections during the holiday season does not seem to be in any way remarkable.

                      Influenza report makes Christmas break. Next flu report published on Thursday 10 January 2013. Influenza Monitoring continues and would something remarkable happen cast as news on the SMI website.

                        Report on the current flu situation

                        Editor: Hélène Englund

                        Influenza in Sweden
                        This week's flu report is based on a small number of reporting laboratories and sentinel units than usual because of the Christmas and New Year holidays and represents the information available in the current situation.

                        The number of laboratory confirmed cases of influenza increased from 97 weeks 51-163 Week 52. Of these, 83 cases (51%), seasonal influenza A, 58 cases (36%) were influenza A (H1N1) pdm09 ("swine flu") and 22 cases (13%) influenza B (Table 1). Despite a lag in reporting, we have not seen the leveling off in the number of laboratory-confirmed cases that occur frequently during the Christmas season.

                          Influenza Report, Week 1 (31/12, 2012 - 6/1 2013) 2013
                          Report on the current flu situation

                          Editor: Hélène Englund

                          Influenza in Sweden
                          Influenza activity increased in the country in Week 1, but is still not remarkable for the season ( Figure 1 ). Total reported 233 cases of laboratory confirmed influenza during the week, of which 107 were A (H1N1) pdm09 ("Swine flu"), 95 seasonal influenza A and 31 seasonal influenza B ( Table 1 ). Influenza A (H1N1) pdm09 has mainly affected children aged 0 to 4 years and adults aged 15 to 64 years, while seasonal influenza A has been most common in people over 65.

                          The number of notifications for A (H1N1) pdm09 doubled compared with the previous week and the trend is very similar to the 2010-2011 season, which was the first year after the pandemic, and dominated by the subtype ( Figure 2 ). Influenza A (H1N1) pdm09 occur throughout the country, but the incidence was during week one maximum in Värmland, who reported 21 of the 107 cases ( Figure 3 ).

                          According to the clinical notifications available for the A (H1N1) pdm09 thus far this season, 67 patients hospitalized, of which 8 have needed intensive care. 84% of those hospitalized have been between 15 and 64 years. This compares with the 2010-2011 season when 119 patients had been hospitalized until Week 1 of which 17 were treated intensive ( flu report week 52-1 2010-2011 ). Overall, the season was reported 401 hospitalized patients, 63 of whom needed intensive care, and ten deaths ( Flu in Sweden 2010-2011 season ).

                          The sentinel reporting, based on patient visits in outpatient care, we have now exceeded the baseline for influenza-like illness (ILI). For week 1 reported 11.9 people per 100 000 inhabitants have sought medical advice because of ILS ( Detailed statistics ). The proportion of samples taken in the sentinel surveillance were positive for influenza have increased steadily since week 49 in 2012 ( Table 4 and depth statistics ).

                          The proportion of people who searched for Vårdguiden.se for flu and flu symptoms continued to increase during week 1 (see Web Search ). The number of questions about fever, cough and sore throat to 1177 medical counseling also increased compared to week 51 ( Contact Causes 1177 ).

                            Influenza Report, Week 2 (7/1 - 13/1), 2013
                            Report on the current flu situation

                            Editor: Hélène Englund

                            Contents
                            Influenza in Sweden
                            Influenza activity increased in the country, even during week 2 ( Figure 1 ). In total 304 cases of reported laboratory confirmed influenza, compared with 231 cases reported in week 1. Of these, 135 influenza A (H1N1) pdm09 ("swine flu"), 121 cases seasonal influenza A and 48 cases, influenza B ( Table 1 and Table 2 ), some A (H1N1) pdm09 cases have since been reported and diagnosed earlier in the season.

                            The increase in the number of laboratory-confirmed cases of seasonal influenza A seems to have stalled somewhat, while influenza B and A (H1N1) pdm09 continues to increase ( Figure 3 ). Development continues to resemble the 2010-2011 season, when we had a moderate and fairly early outbreak of A (H1N1) pdm09, but got a sharp peak of influenza B late in the season. Because all influenza seasons develop differently, it is difficult to predict what the near future will be developed, but it appears so far that the spread of A (H1N1) pdm09 has not accelerated as much in Sweden as it has previously done in Norway.

                            Influenza A (H1N1) pdm09 has primarily been demonstrated among children between 0 and 4 years of age and in adults between 15 and 30 years, while seasonal influenza A was most common in people over 65. Influenza B has so far affected all age groups fairly evenly. According to the clinical notifications for A (H1N1) pdm09 has all season 111 patients hospitalized, 12 of which have needed intensive care. The majority of intensive caring has been between 40 and 75 years. A man in late middle age with several underlying and serious risk factors for severe disease have died. His vaccination status is still unclear.

                            A (H1N1) pdm09 found throughout the country ( Table 3. Number of reported A (H1N1) pdm09 cases per county ). Incidence week 2 was still highest in Värmland, but the outbreak appears to still be decaying there ( Figure 2 ). (After the reporting of influenza A (H1N1) pdm09 cases causing an apparently higher incidence of Västra Götaland and Södermanland for week 2 than would otherwise be the case.)

                            The sentinel reporting, we are above the baseline for the proportion of doctor visits for influenza-like illness (ILI) outpatient ( Figure 4 ). For week 2 reported 10.8 people per 100 000 inhabitants have sought medical advice because of ILS ( Table 4 ). within sentinel sampling, the number of submitted samples almost doubled from week 1, a total of 127 samples were received during the two weeks compared to 65 weeks samples first The percentage of positive samples for influenza have decreased from 40% to 23% ( Figure 5-6 , Table 5-6 ). This suggests that other than influenza viruses currently gives flu-like illness (see Other viral causes of respiratory infections in Sweden ) Web Searchlight graph of the number of people who searched for Vårdguiden.se for influenza-like illness plateaued at week 2 ( Web Search ). The number of people contacted in 1177 with questions about fever, cough and sore throat in adults and children fell for the second week in a row, but the number of searches is higher than normal for the season.

                            In summary, talking reports of care for increasing influenza activity, but the intensity is still normal for the season.

                            We would once again like to remind you that this year's seasonal vaccine contains three virus types circulating including A (H1N1) pdm09, and that there is the same vaccine that was given in the context of the pandemic. Seasonal vaccine has now been over three seasons to an estimated 1 billion people worldwide without any notable adverse reactions have been identified.

                            Information on seasonal vaccine and who belong to the risk group for severe disease and therefore recommended vaccinations available on the Board's website .
                            More detailed information on this year's vaccines are on SMI's website .

                              Influenza Report, week 3 (14/1 -20 / 1), 2013
                              Report on the current flu situation

                              Editor: Hélène Englund

                              Influenza in Sweden
                              During week 3 were reported slightly more laboratory confirmed influenza cases than last week, 361 compared to 320 ( Table 1 and Table 2 ), but the increase seems to have leveled off. Even in other countries in Europe are the same trend (see Influenza in the world ). From outpatient reported slightly more patients with influenza-like illness (see Sentinel Surveillance ) and even syndromic surveillance Web Search is still upward. The sentinel sampling was 23% of the samples taken during week 3 positive for influenza virus. This proportion has fallen two weeks in a row from 37% in week 1.

                              We continue to influenza A (H1N1) pdm09 mainly affects children under four years of age and adults between 15 and 64 years, while other influenza A primarily affects the elderly over 65 years. Approximately thirty percent of the reported cases of influenza A (H1N1) pdm09 has been reported as hospitalized. Of these, 49% had one or more risk factors for severe disease, in which the most common were immunocompromised, chronic heart or lung disease. So far the season has been two deaths reported. Both of them suffered from severe underlying disease.

                              The overall picture suggests that the flu could be on track to reach its peak and that the season may be milder than it was last season when the 2011-2012 influenza A (H3) dominated.
