"There were three consecutive weeks when the entire continental US was affected by flu at a very high level," she said.Adams said that getting the flu shot by the end of October is not just about keeping yourself safe and healthy, it's also about community. Table 3 summarises the laboratory reporting results over the last five seasons, including the number of analysed samples and the proportion of positive samples as well as the total samples positive by type, subtype, and lineage. The majority of the laboratories did not detect influenza B in the sample with the lowest viral load. Forty-two of the collected samples with Ct ≤ 30 were cultured on MDCK cells. The 6B.1 genetic group also dominated (1,882 out of 1,885 viruses) among those reported in the European surveillance system during the 2018–2019 season (11). Speaking at the same conference, Dr. Laura E. Riley, professor and chair of the Department of Obstetrics and Gynecology at Weill Cornell Medicine, said that less than half of all pregnant women -- 49% -- received a flu shot last year. During the 2018–2019 season, sales first increased steeply to their highest value toward the end of December (week 51), ahead of the Christmas holidays, at the same time as the number of influenza cases increased significantly. Follow daily preventive actions such as washing your hands, covering your cough and staying home if sick. After the peak in week 6, however, the proportion of influenza A(H3N2) started to increase, and in week 10 the dominating subtype of influenza A shifted from A(H1N1)pdm09 to A(H3N2). Table 10 shows that the proportion of deaths within 30 days increased with increasing age and varied from 0.2 percent for persons aged under 40 years to 23% for people aged 95 years and older. The reported data include the number of calls related to cough, fever, and sore throat. Only a limited number of cases of influenza B were reported during the season.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. In January 2019, additional doses were delivered to Sweden, but by then efforts to vaccinate and interest in vaccination had decreased.During the season, 359 patients with influenza were reported as having received intensive care across the country, which is fewer than during the previous season. "But give the vaccine credit for softening the blow. In addition, four patients without any reported risk factor were vaccinated. During the peak week (week 6), the number of cases (1,296) was also similar to the peak week of 2016–2017 (see Figure 2). The age group and main reason for calling are registered for all callers. The FluMoMo model estimates excess mortality due to either influenza activity or extreme temperatures, both nationally and by age group.In total, 505 of 13,324 persons who received a laboratory-confirmed influenza diagnosis during the 2018–2019 season died within 30 days of diagnosis.
They include good old-fashioned hand-washing, covering your mouth when you cough, and staying home if you’re sick.80,000 Americans died of the flu last winter.

Of these, 134 (10%) were vaccinated. there were too few influenza b strains to determine the vaccination effect.>All diagnostic laboratories perform influenza typing using molecular assays for influenza A and B. Faster and increased availability of virological analysis of samples has most likely contributed to the increase of both sampling and the reported number cases from outpatient care settings. The haemagglutinin (HA) gene is characterised with respect to genetic vaccine similarity, clade affiliation, and changes in receptor affinity (lung receptors versus upper respiratory tract receptors). Typing results for subtype and lineage from sentinel and laboratory reporting systems are presented in Table 12.A selection of the influenza-positive samples from laboratories and from the sentinel surveillance programme are further analysed for genotypic features by sequencing and for phenotypic sensitivity to neuraminidase (NA) inhibitors. For Skåne, there are two estimates of the coverage each season; 2017–2018: financial system (54.7%), vaccination register (45.3%); 2018–2019: financial system (57.1%), vaccination register (48.0%). Approximately 5–10 percent of the population under 65 years of age belongs to a medical risk group.Thirteen county councils (see note under Table 15) have reported the number of persons vaccinated under 65 years of age, although risk group status is often unknown. Webbsök is an automated system established in 2008 that uses a statistical model and completely anonymous data from a medical advice website to estimate the development of sentinel ILI incidence. Recently circulating viruses, all with S74R, S164T, and I295V substitutions (subgroup 6B.1A) and with the majority also having S183P, have shown good reactivity with ferret antiserum raised against the 2018–2019 vaccine virus A/Michigan/45/2015 (clade 6B.1) (12). Influenza B viruses are 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. An average of 24 percent of calls in this age group concerned fever throughout the season, and the highest proportion of calls (33 percent) was registered during week 6, 2019.A noticeable peak in calls is often seen around the Christmas holidays every year, followed by a drop. Kits used by two or more laboratories are selected for extra quality controls during the season in order to ensure that circulating influenza strains are detected with these assays. The laboratories in Sweden reported 13,757 influenza cases during the season, which was fewer cases than in the previous season. The Centers for Disease Control and Prevention estimates that so far this season, there have been at least 15 million flu illnesses for the 2019-2020 season, 140,000 hospitalizations and 8,200 deaths in the U.S.
