by Patricia L. Foster The 2017-2018 flu season was historically severe. Total flu fatalities during the most recent season included the deaths of 180 children, which exceeds the previous record high of 171 during a non-pandemic flu season, according to the CDC. Everything you need to know about the flu illness, including symptoms, treatment and prevention. The common way of producing influenza vaccine starts by growing the virus in fertilized chicken eggs. After several days, the viruses are harvested, purified and inactivated, leaving the surface proteins, HA and NA, intact. Most years the vaccine is well matched to the circulating virus strain, and even a poorly matched vaccine offers protection. The severity of the flu varies depending on the person, the flu season, and the flu virus active that year. Number of deaths from influenza in Spain 2005-2018; U.S. adults who did not prevent the spread of germs when they had the flu as of 2017; Places U.S. adults visited when they had the flu as of 2017 Complications that can arise from the flu and result in death include stroke, heart attack and pneumonia. National Center of Health Statistics also collects estimated weekly information of flu deaths, based on death certificate data. Ineffective flu vaccine added to 50,000 extra deaths last winter, ONS says. On the national scale, influenza and pneumonia deaths gradually decreased between 1999 and 2017. Flu complications, such as pneumonia, can result in hospitalization or even death. The severity of the flu varies depending on the person, the flu season, and the flu virus active that year. There were two big factors. One, a vaccine made from viruses grown in mammalian cells, proved in preliminary studies to be only 20 percent more effective against A(H3N2) than egg-produced vaccine. A is the most serious and C is rare, producing only mild symptoms. "The thing that was most notable about last year was how high in terms of activity things were," said Nordlund. Overall, the effectiveness of the seasonal flu vaccine for last season was estimated to be 40%. Flu "can be serious even for healthy adults and healthy children," said Adams adding, "I'm going to get my flu shot today.". One effort relies on the fact that flu’s HA protein “stalk” is less variable than the “head” that interacts with the host cell surface; but vaccines made from a cocktail of HA protein “stalks” have proved disappointing so far. Flu during pregnancy can also harm the baby, she said. Is your family prepared? If an animal is simultaneously infected with two different subtypes, the segments of their genomes can be scrambled together. We said Thank you for your enquiry. In the 2018-2019 flu season, about 34,200 people died from the flu in the United States, according to a preliminary estimate from the Centers for Disease Control and Prevention (CDC). At every trimester, the flu vaccine is safe and effective for both pregnant women and their fetuses, plus it protects babies after they are born, preventing flu in the first six months of their lives when they are too young to get their own flu shot, she said. The first two weeks of 2020 show that there have been 887 deaths due to flu in America. "One hundred and eighty kids -- this really hit me hard as the father of three kids -- died last year from the flu. This burden was similar to estimated burden during the 2012–2013 influenza season1. Against this background of antigenic change, every year the World Health Organization predicts which strains of flu virus will be circulating during the next flu season, and vaccines are formulated based on this information. This part of the meme is accurate. So, although the same strains will most likely be circulating, epidemiologists expect the vaccines to provide better protection. (CNN)An estimated 80,000 Americans died of flu and its complications last winter, according to the US Centers for Disease Control and Prevention. Two new vaccines that do not use egg-grown viruses are currently available. The first flu death of the 2018-2019 season has already occurred – a healthy but unvaccinated child died in Florida – affirming the importance of getting the flu shot. 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. Influenza is not a single, static virus. Influenza—the flu—is caused by a virus, with symptoms including coughing, fatigue, and fever. This means it was the deadliest season in more than four decades -- since 1976, the date of the first published paper reporting total seasonal flu deaths, said CDC Spokeswoman Kristen Nordlund. When flu strikes during pregnancy, there's a greater likelihood of hospitalization for the mother-to-be, she said. During the spring months of March–May, influenza B virus became dominant. But, significantly, it was only 25 percent effective against the especially dangerous A(H3N2) strain. The most at-risk populations include seniors and young children as their immune systems are more likely to be compromised. The CDC recommends that everyone 6 months and older get a flu shot every year, but, typically, fewer than half of Americans do so. In addition, most of the vaccine produced was mismatched to the circulating A(H3N2) subtype. The higher number reflects the particularly harsh 2017-2018 flu season. Date: 2018. Your immune system reacts first to these two proteins. And, he said, get treated quickly and take antiviral drugs if your doctor prescribes them. Although the immune system may be prepared to shutdown previously encountered strains, even slight changes can require the development of a completely new immune response before the infected person becomes resistant. It's your "social responsibility to get vaccinated," he said, since it protects others around you, including family, friends, co-workers and neighbors. These vaccines are designed to stimulate the “memory” immune cells that persist after an infection, possibly providing lasting immunity. Updated 1645 GMT (0045 HKT) September 27, 2018. In addition, various subtypes of influenza A infect animals, the most important of which, for humans, are domestic birds and pigs. The most at-risk populations include seniors and young children as their immune systems are more likely to be compromised. High fever for an extended period can cause birth defects and lead to premature birth. That said, Schaffner warned that flu is "unpredictable. The estimates by the NCHS show that more than 7,500 Americans died from the flu between January 5 and May 9, 2020. Public health officials estimate that 900,000 Americans were hospitalized and 80,000 died from the flu … Influenza killed about 80,000 people in the 2017-2018 season, according to figures released by the Centers for Disease Control and Prevention. This percentage is above the epidemic threshold of 7.0% for week 1. ", As of September 9, Australia is experiencing a mild flu season with person-to-person transmission of flu-like illness "increasing slowly" since July, according to that nation's most recent. Influenza and pneumonia rank among the most deadly illnesses in the United States. The 2017–2018 United States flu season lasted from late 2017 through early 2018. While the flu is not typically fatal, it is highly contagious and can be deadly to children, seniors, and other vulnerable populations in New York. Viruses consist of protein packages surrounding the viral genome, which, in the influenza virus, consists of RNA divided into eight separate segments. In 2017-2018 the vaccine was directed against specific subtypes of A(H1N1), A(H3N2) and B. Read the original article. In recent flu seasons, deaths from the virus have ranged from about 12,000 to 56,000. Scientists are on the hunt for a better way to protect the world’s population from influenza. A vaccine composed of two proteins internal to the virus, M1 and NP, which are much less variable than surface-exposed proteins, is in clinical trials, as is another vaccine made up of a proprietary mixture of pieces of viral proteins. First, one of the circulating strains of the influenza virus, A(H3N2), is particularly virulent, and vaccines targeting it are less effective than those aimed at other strains. "It is critical that we help pregnant women not get the flu." Can you tell me the influenza deaths per each region England in 2018? "Pregnant women who get the flu do very poorly," said Riley. When people receive vaccines produced from these egg-adapted viruses, their immune system learns to target the egg-influenced HA proteins and may not react to the HA proteins on the viruses actually circulating in humans. The influenza virus is enveloped by a membrane layer derived from the host cell. In 2018, 650,000 of an estimated 7.5 billion people, or 0.009%, died of the seasonal flu worldwide. Plus, wide-spread vaccination stops the virus from spreading and protects the vulnerable. She added, "across the board, last year was definitely bad.". "The vaccine is not perfect," said Schaffner. "There were three consecutive weeks when the entire continental US was affected by flu at a very high level," she said. Small improvements and a universal vaccine. Sign up here to get The Results Are In with Dr. Sanjay Gupta every Tuesday from the CNN Health team. Thus we have seasonal flu outbreaks. The predominant strain of influenza was H3N2. She said "kids are more likely to be immunized if their parents are" adding everyone 6 months and older should get a flu shot, which is the recommendation of the CDC. This mismatch probably reflects the way most of the vaccines are produced. CDC estimates that vaccination helped prevent 4.4 million illnesses, 58,000 hospitalizations and 3,500 deaths during the 2018-2019 flu season. news conference hosted by the National Foundation for Infectious Diseases on Thursday, Flu vaccine, even when just 20% effective, saves tens of thousands of lives, 'Australian flu': It's not from Australia, Flu caused an estimated 80,000 deaths last fall and winter, The 2017-18 season ranks as the deadliest in more than four decades, Record 900,000 flu hospitalizations last year. Age: Total all ages. In the 2016-17 season, there were an estimated 29 million flu cases in the United States; and estimated 497,000 flu-related hospitalizations and 38,000 flu-related deaths. In a typical season, 30,000 Americans die. This process, called antigenic shift, is responsible for the major pandemics that have swept the world in the last century. Influenza and pneumonia rank among the most deadly illnesses in the United States. Patricia L. Foster, Professor Emerita of Biology, Indiana University. February 9, 2018, 1:54 PM EST Updated on February 9, 2018, 4:53 PM EST Flu Is Causing 1 in 10 American Deaths and Climbing Along with the pneumonia it spawns, this year’s epidemic may be … ", Looking ahead to the coming winter months, Australia's flu season, which precedes that in the Northern Hemisphere nations, is often an indicator of what's to come in the US, Canada and across Europe. The Centers for Disease Control and Prevention estimates that this vaccine was 40 percent effective in preventing influenza overall. She explained that during pregnancy, even a healthy pregnancy, the immune system is not working full throttle. Flu season is around the corner. Both HA and NA proteins are constantly changing. That is a significantly lower total than the 100,000 deaths tweeted by President Trump. Experts called this a "typical year," according to the meme. speaking at a. Additionally, the nation experienced a record-breaking estimated 900,000 hospitalizations last flu season. Public health officials estimate that 900,000 Americans were hospitalized and 80,000 died from the flu and its complications. Gender: Total "The increase is thought to be down to the flu, the ineffectiveness of the flu vaccine in older people and spells of very cold weather last winter." CDC estimates that influenza was associated with more than 35.5 million illnesses, more than 16.5 million medical visits, 490,600 hospitalizations, and 34,200 deaths during the 2018–2019 influenza season. This article is republished from The Conversation under a Creative Commons license. Human suffering and lost lives over winter 'predictable, preventable and shameful', fuel poverty campaigners say The most at-risk populations include seniors and young children as their immune systems are more likely to be compromised. There were two big factors that led to the deaths. "But give the vaccine credit for softening the blow. Based mainly on the recent flu season in South America, the World Health Organization recommended changing the A(H3N2) subtype in the vaccine to one that better matches last year’s circulating A(H3N2). Influenza—the flu—is caused by a virus, with symptoms including coughing, fatigue, and fever. There are three species – A, B and C – that can infect people. Most years, the US death toll from the flu is closer to 34,000 to 43,000. Deaths by Influenza for 2018 can be found using our NOMIS webservice. Adams noted that a variety of vaccines have been officially approved this year, including nasal mist, and that they are widely available, including in doctor's offices, local pharmacies, some work places and even certain groceries stores. The 2017-18 season ranks as the deadliest in more than four decades Record 900,000 flu hospitalizations last year (CNN) An estimated 80,000 Americans died … "There were around 50,100 excess winter deaths in England and Wales in 2017-18 - the highest since the winter of 1975-76, figures from the Office for National Statistics show. The severity of the flu varies depending on the person, the flu season, and the flu virus active that year. Adams stressed that flu is "especially deadly for older adults, pregnant women, people with chronic conditions and children" and he recommended everyone take additional steps to avoid the flu this coming season. Flu is further divided into various subtypes and strains, based on the viral properties. And the majority of them were unvaccinated," said US Surgeon General Dr. Jerome M. Adams. The 2017-2018 flu season was historically severe. On the national scale, influenza and pneumonia deaths gradually decreased between 1999 and 2017. Flu deaths 2018: 80,000 Americans died of the flu last winter - Vox 80,000 Americans died of the flu last winter. The other, a “recombinant” vaccine consisting of only the HA proteins, is produced in insect cells, and its effectiveness is still being evaluated. Dr. William Schaffner, medical director for the National Foundation for Infectious Diseases, said that those who get flu after receiving vaccine are less likely to require hospitalization and they're less likely to die. For the 2017-2018 season, 185 pediatric flu deaths were reported. In previous seasons, flu-related deaths have ranged from a low of about 12,000 during the 2011-2012 season to a high of about 56,000 during the 2012-2013. She explained that last season, unlike previous seasons, flu did not strike one region of the country and then move across the land. "We love them, but they are a lot of the reason flu moves around the community.". Any resulting virus may have new properties, to which humans may have little or no immune defense. The WHO anticipated that the circulating A(H1N1) subtype will be the same as last year and so no change was necessary on that front. On the national scale, influenza and pneumonia deaths gradually decreased between 1999 and 2017. "Kids have a lot of snot, they have a lot of drool and they go to school," she said over laughter from the audience. While the flu is not typically fatal, it is highly contagious and can be deadly to children, seniors, and other vulnerable populations in West Virginia. This evolution of the HA and NA proteins, called antigenic drift, prevents people from developing lasting immunity to the virus. Advertisement Between 184,000 and 221,000 people have been hospitalized with the flu so far this season. (For comparison, 36,560 people died in car accidents in 2018 in the United States.) The ideal solution is a “universal” vaccine that would protect against all influenza viruses, no matter how the strains mutate and evolve. The overall burden of influenza for the 2012-2013 season was an estimated 34 million influenza illnesses, 16 million influenza-associated medical visits, 571,000 influenza-related hospitalizations, and 43,000 flu-associated deaths (Estimated Influenza Disease Burden, by Season — United States, 2010-11 through 2017-18 Influenza Seasons). This means the flu vaccine reduced a person's risk of having to seek medical care by 40%, the CDC found. Among the 3,337 PIC deaths reported for week 1, 2,486 had COVID-19 listed as an underlying or contributing cause of death on the death certificate and two listed influenza, indicating that the current increase in PIC mortality is due primarily to COVID-19 and not influenza. Severity is based on flu activity, hospitalizations, and deaths from pneumonia or influenza, explained Nordlund. Flu deaths in 2018 are making headlines because they’ve struck down people you’d think wouldn’t be in peril from such a common virus. For years, the American people have been lied to about flu shots and flu related deaths! The season began with an increase of illness in November; high activity occurred during January and February, and then illness continued through the end of March. Follow daily preventive actions such as washing your hands, covering your cough and staying home if sick. The process that copies the viral RNA genome is inherently sloppy, plus these two proteins are under strong pressure to evolve so they can evade attack by the immune system. Flu and its complications can be life-threatening, particularly for the young, the old and the otherwise debilitated. Thus, the virus used to produce much of the 2017-2018 vaccine provoked an immune response that did not fully protect against the A(H3N2) virus circulating in the population – although it may have lessened the severity of the flu. These problems reflect the special biology of the influenza virus and the methods by which vaccines are produced. Dr. Wendy Sue Swanson, another conference speaker and chief of digital innovation and digital health at Seattle Children's Hospital, stressed that it's very important for children to get vaccinated. 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. In recent years, flu-related deaths have ranged from about 12,000 to — in the worst year — 56,000, according to the CDC. For comparison, the previous worst season from the past decade, 2010-2011, saw 56,000 deaths. The CDC has been telling the public for nearly a decade that there are more than 200,000 estimated hospitalizations and 36,000 estimated deaths from influenza in the U.S. every year. These page includes information about the estimated burden of influenza from … Overall, the United States experienced one of the most severe flu seasons in recent decades. © Copyright 2021 Center for the National Interest All Rights Reserved, 900,000 Americans were hospitalized and 80,000 died, various subtypes of influenza A infect animals, major pandemics that have swept the world, which strains of flu virus will be circulating, growing the virus in fertilized chicken eggs, on the viruses actually circulating in humans, may have lessened the severity of the flu, vaccine made from viruses grown in mammalian cells, vaccines made from a cocktail of HA protein “stalks”. Get your flu shot. Their properties determine the H and N designations of various viral strains – for instance, the H1N1 “swine flu” that swept the globe in 2009. So why was the 2017-2018 season such a bad year for flu? But, when the virus is grown in eggs, individual viruses with changes in the HA protein that increase its ability to bind to chicken cells can grow better and thus become more common. The death toll from influenza in California rose sharply on Friday, amid a brutal flu season that has spread across the nation. Mortality Statistics- underlying cause, sex and age. (The CDC never made a … Sticking through this membrane are spikes made up of the proteins haemagglutinin (HA) and neuraminidase (NA), both of which are required for the virus to successfully cause an infection. They also recommended changing the B subtype to one that appeared in the U.S. late in the 2017-2018 season and became increasingly common elsewhere. () However, these numbers are not truthful!They do not represent people who actually died from the flu.
