คนอเมริกันตายจากเชื้อไข้หวัดใหญ่ สถิติมากขึ้นเรื่อยในช่วง 2 สัปดาห์ที่ผ่านมา ปีนี้เพิ่มสูงมากหลังจากที่เคยพบไข้หวัดหมูเมื่อปี 2009 Flu epidemic: By the end 50,000 WILL BE DEAD and its kids who are spreading it A DEADLY flu epidemic spreading across the United States is likely to kill more than 50,000 people and is infecting people at a rate not seen since the 2009 swine flu pandemic, health officials have warned. The disease is hitting America particularly hard this year, with cases reported across the entire mainland and an aggressive strain of the virus affecting a broader age range than usual. And according to experts, the unusually high rates of infection are being driven by children returning to school after the Christmas holidays. So far 37 children have died in America from a resistant strain of the virus, and government officials say the number could double before flu season is over. Seven children died of flu just last week. https://www.express.co.uk/news/world/911394/flu-season-epidemic-2018-sym ptoms-latest-spread-news-cdc#t=1m4s

มีรายงานข่าวว่าวัคซีนไข้หวัดใหญ่ที่ฉีดไป ได้ผลแค่ 10% ในปีนี้ เป็นสาเหตุของการแพร่เชื้อไข้หวัดใหญ่ที่ระบาดข้ามประเทศ เนื่องจากสายพันธุ์ของเชื้อไข้หวัดใหญ่มีการเปลี่ยนแปลงไปจากเดิม The flu vaccine is only 10 percent effective this year. Blame eggs. Flu vaccine production methods arent a good match for this years circulating virus type. The first data on how well the flu vaccine is working this season in North America has just been published and it helps explain why everyone appears to be sick right now. The study, from the journal Eurosurveillance, found that the flu vaccine was only 10 percent effective against H3N2 (the main flu subtype going around this season) among adults in Canada. That means the shot only prevents 10 percent of flu cases. So if 100 in 1,000 unvaccinated people develop flu, the number would drop to 90 in 1,000 among vaccinated people a very small difference in flu risk between vaccinated and unvaccinated individuals. The evidence is mounting, from Australia and now from Canada, that the vaccine protection is low [this year], said lead study author Danuta Skowronski, an influenza epidemiologist at the British Columbia Center for Disease Control. Whenever H3N2 is the dominant flu strain, vaccines dont work as well There are four species of influenza viruses A, B, C, and D and seasonal flu is caused by influenza A and B. Every year, different strains of these viruses circulate. To formulate the flu vaccine, public health agencies essentially make early educated guesses on which strains will make the rounds. And thats not easy. https://www.vox.com/science-and-health/2018/2/1/16960758/flu-vaccine-eff ectiveness
