Of these, 134 (10%) were vaccinated. The HA, M, NS, PB1, PB2, and PA gene originated from seasonal A(H1N1)pdm09, while the NA gene originated from seasonal A(H3N2). I denna åldersgrupp sågs en utdragen aktivitet när A(H3N2) började dominera säsongen.
During the 2018–2019 season, 1,323 sentinel samples were submitted from 73 participants, including 68 general practitioners and 5 paediatric or infectious disease clinics. All inactivated influenza vaccines that were available for procurement for the 2018–2019 season ran out at the suppliers during the autumn of 2018 and were officially listed as under a medicine shortage. The majority of the cases (>99%) during the peak (week 6) were influenza A, and based on the samples that were subtyped influenza A(H1N1)pdm09 was the dominating subtype during the season overall. Viruskarakteriseringen görs på ett urval av de stammar som samlas in genom sentinelprovtagningen och från laboratorier i landet. The 10 samples analysed by real-time PCR were correctly typed (A or B), and 9/10 were correctly subtyped. Figure 15. The seven samples analysed by NGS were all correctly reported. ~2% coverage among risk groups under 65 years. Knotts Scary Farm – Thrills and Chills Unlimited!
prescriptions and healthcare requisitions. Coverage in this age group was slightly higher than the previous season (2017–2018), when the final coverage estimate was 50 percent. Figure 9. Overall, 7 percent of those aged 65 years and older who received a laboratory-confirmed influenza A diagnosis died within 30 days. However, it is essential that you choose the right time to visit the country to be able to really enjoy the activities that you enjoy and seek. Incidensen i Svealand och Götaland var högst under vecka 5 respektive 6. When new strains of influenza virus emerge, reference methods for diagnostics are established at the Public Health Agency and shared with all microbiological laboratories in Sweden.
‡ Population on December 31, 2018. Our reasoning for presenting offensive logos. Table 1 describes the data collection systems that the Public Health Agency used to monitor influenza activity at the various levels of the influenza pyramid in Sweden during the 2018–2019 season and shows a summary of results of each system.
There is an important weather divergence between northern and southern Sweden: The north has a long, harsh winter of more than seven months, while the south has winter weather for only two months and a summer of more than four. Between week 50, 2018, and week 10, 2019, participants received weekly surveys with questions on their health status for the preceding week. Figure 8. Även incidensen av laboratorieverifierade fall var hög i denna åldersgrupp jämfört med föregående säsonger. Percentage of the population with ILI and ARI per week and age group. However, in an antigenic assay using post-vaccination paediatric sera, recent 6B.1 viruses having the S74R, S164T, and I295V along with the S183P substitution were antigenically distinguishable from cell culture and egg-propagated A/Michigan/45/2015 viruses (6). Terri Mapes specializes in giving first-time Scandinavia visitors practical tips for their travels. Analyses by WHO CC London showed that this virus was antigenically similar to the current vaccine virus A/Michigan/45/2015 and phenotypically sensitive to both oseltamivir and zanamivir.
Start of the epidemic is marked with a black dot. The greatest number of patients were admitted to intensive care during week 7 (36 patients), which is the week after the laboratory-confirmed cases of influenza peaked. In total, 408 samples (31%) tested positive for influenza.
SIRI: Swedish Intensive Care Registry – Influenza module.
Percentages were calculated using the county population on December 31 of each year (Source: Statistics Sweden).
Under vaccinbristen publicerade Folkhälsomyndigheten uppdaterade rekommendationer för prioritering av och mellan riskgrupper (1). Virological analysis of samples from sentinel general practitioners, infectious disease clinics, and paediatric clinics contributes to national and international surveillance of circulating influenza viruses.
Sett över hela säsongen var 76 procent av fallen A(H1N1)pdm09 och 24 procent A(H3N2). The Public Health Agency participates in the European Influenza Monitoring Vaccine Effectiveness (I-MOVE) network with data from Swedish sentinel sampling. An automated system that uses search data from the national medical advice site 1177.se. site copyright 2012 Travel Signposts and ZambaGrafix, Travel Resources that will save you time and money. The incidence in the middle and southern parts of Sweden was highest during weeks 5 and 6, respectively. The Scandinavian mountains are blocking warm air masses from above the Atlantic resulting colder weather of northern and western regions. Genotypic and phenotypic antiviral susceptibility determination. * Epidemic thresholds/intensity levels not assigned.

Samples from some patients who present with influenza-like illness (ILI), as well as some patients with acute respiratory illness (ARI), are analysed by the Public Health Agency for influenza. During these months, the days are long and the country's natural beauty is at its peak. We found that we had problems with isolation of influenza B. Overall, 16.5 percent of the samples taken were positive for influenza, which is lower compared to previous seasons, in part reflecting the lower intensity of the season (Table 3, Figure 3). European cruises from CruiseDirect. Most samples of influenza A and B were not analysed for subtype or lineage, respectively. A large number of patients (34 patients) were also admitted to intensive care in week 52 at the start of the seasonal epidemic.
In total, 1,949 influenza A-positive samples were subtyped during the season, of which 1,228 (63%) were A(H1N1)pdm09) and 721 (37%) were A(H3N2). Influenza A(H1N1)pdm09 dominated until week 10, when dominance shifted to influenza A(H3N2). Table 3. September, in particular, can be a nice time to visit, as temperatures are typically still above 60 degrees Fahrenheit. Get great deals on passes and tickets here.
However, during winter, there's much more variation, with temperatures ranging from freezing all the way down to 5 degrees Fahrenheit near the Finnish border. Fourteen of the vaccinated patients were aged 65 years and older, and the median age for all vaccinated was 58 years. Tourists can expect good weather in Aug instead of rains. During the 2018–2019 season, 35 virus isolates and 24 clinical samples were shipped to the WHO CC London for further characterisation (one shipment in January and one in June). Figure 19. The Public Health Agency performs subtyping and lineage typing by real-time PCR for all samples sent in from the diagnostic laboratories and on all positive samples from sentinel surveillance.
The elderly have a certain level of immunity to this type of influenza.
The two isolates analysed phenotypically by NAI-assay (fluorescence-based MUNANA) were both correctly reported. HA - Haemagglutinin. Swedish laboratories are also asked to send influenza-positive samples from severely ill or deceased patients, patients with vaccine break-through infections, and patients who do not respond to antiviral treatment.
The age for vaccinated patients ranged from 2 to 84 years, with a median age of 70 years. Summers in the north are short and cool, but the rest of the country is generally very comfortable and quite warm.
The ski season is longer than in the Alps, in fact, the final races of the ski World Cup are often held in Sweden, in March (eg in Åre). During the initial weeks of the epidemic, the northern parts of Sweden (Norrland) had higher incidence in comparison to the middle (Svealand) and southern (Götaland) parts of the country (Figures 8 and 9). The most popular time of year to visit Sweden, at least as far as tourist activity goes, is mid-to-late summer. No mutations associated with reduced or highly reduced inhibition were detected.
The percentage of samples positive for influenza showed a similar geographic trend with peaks in weeks 1–2 and 7 for the northern part of the country (Norrland), weeks 6–7 for the middle (Svealand) and southern (Götaland) parts of the country. Sometimes, during times of high solar activity, the Northern Lights can be seen from as far south as Stockholm and Gothenburg. Weekly incidence of influenza A per age group in Sweden, 2018–2019 season. To ensure that the analyses performed at the Public Health Agency are correct, the agency participates in different external quality assurance programmes.
