The current 2019-20 burden estimates are lower than those provided in April 2020 because of expected changes in available data on flu testing practices in patients hospitalized with flu, as well as unexpected data delays due to the onset of the COVID-19 pandemic in Spring 2020. The method used to estimate flu-related deaths relies on additional data from FluSurv-NET and the National Center for Health Statistics (NCHS) (data on cause of death and numbers of deaths that occur inside versus outside of the hospital). Please also see the following dataset: Deaths registered in England and Wales. Patterns of fatality. First, rates of influenza-associated hospitalizations are based on data reported to the Influenza Hospitalization Surveillance Network (FluSurv–NET) through October 1, 2019. Thus, reports of laboratory-confirmed flu-related hospitalizations to FluSurv-NET are underestimates of the true number of hospitalizations. 2019 of 558.3 infant deaths per 100,000 live births did not change significantly from the rate … Final case counts may differ slightly as further data cleaning from the 2019-2020 season are conducted by FluSurv–NET sites. It was reviewed by clinical, epidemiological and virological experts. To calculate these ratios, first we calculate the frequency of flu-related deaths reported from our FluSurv-NET surveillance system that have cause of death identified as pneumonia or influenza (P&I), other respiratory or cardiovascular (other R&C), or other non-respiratory, non-cardiovascular (non-R&C). CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. The shaded area indicates weeks where the positivity rate was at least 5% and a minimum of 15 positive tests were observed, signalling the period of seasonal influenza activity. More than 46,000 hospitalizations occurred in children (aged <18 years); however, 57% of hospitalizations occurred in older adults aged ≥65 years. Die Influenza, auch (echte) Grippe oder Virusgrippe genannt, ist eine überwiegend durch Viren aus der Gruppe der Orthomyxoviridae und den Gattungen Influenzavirus A oder B ausgelöste Infektionskrankheit bei Menschen. The 2019-20 season is described as having moderate severity; however, the effect of influenza differed by age group and the severity of the season in some age groups was higher. Select cause of death (ICD10 code search is available). Freedom of Information | Released on 8 September 2020 Influenza deaths in 2018, 2019 and 2020 . We used death certification data from all influenza seasons from 2010–2011 through 2017–2018 where these data were available from the National Center for Health Statistics. Select format (Excel or CSV for example) This will provide you with a dataset showing the number of deaths from influenza in 2019.

These rates mean that an estimated 15 million cases of influenza in younger adults (aged 18-49 years), which is the highest number of infections for this age group since CDC began reporting influenza burden estimates in the 2010-11 season. Furthermore, our model uses the frequency of influenza-related deaths that have cause of death related to pneumonia or influenza (P&I), other respiratory or cardiovascular (other R&C), or other non-respiratory, non-cardiovascular (non-R&C) to account for deaths occurring outside of a hospital by cause of death. Activity– Currently, influenza and influenza-like illness (ILI) activity is lower than average for this time of year compared to previous years, and is consistent with past activity following a peak in notifications and coming to the end of the influenza season. During the 2019-2020 influenza season, CDC estimates that influenza was associated with 38 million illnesses, 18 million medical visits, 405,000 hospitalizations, and 22,000 deaths. These symptoms typically begin 1–4 … By contrast, simple peri-season rate-difference models may prove useful for estimating morta … 22,000 flu deaths, enough people to fill Madison Square Garden in New York City. The Y axis goes to 1%. These estimates are an update to the preliminary in-season 2019-20 burden estimates published April 2020 and are based on more recently available information. However, influenza-associated pediatric deaths are likely under-reported as not all children whose death was related to an influenza virus infection may have been tested for influenza9,10. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. Data to generate these frequencies were not available from the 2019–2020 season at the time of estimation, so we used the average frequencies of location of death for each of the cause categories from previous seasons, 2010–2011 through 2017–2018. We estimate, overall, there were 490,600 hospitalizations and 34,200 deaths during the 2018–2019 season. Influenza mortality in symptomatic cases in the US for the 2018/2019 season. The preliminary in-season 2019-20 burden estimates were made using the highest flu testing rate for each age-group from the 2010-2011 through the 2016-2017 seasons. Please also see the following dataset: Deaths registered in England and Wales. The PHE report published at 2pm on 3 January 2019 suggests that influenza is starting to circulate in the community and is at moderate levels. Influenza season 2019 ... are already seeing increased rates of influenza hospitalisation. However children less than 5 years old also reported a relevant influenza attributable excess death rate in the 2014/15 and 2016/17 seasons (1.05/100,000 and 1.54/100,000 respectively). Influenza was associated with substantial excess respiratory mortality in China between 2010–11 and 2014–15 seasons, especially in older adults aged at least 60 years. 1. However, data from FluSurv-NET that is usually available at the end of flu season was delayed in 2020 due to the onset of the COVID-19 pandemic. Influenza, commonly called "the flu", is an infectious disease caused by influenza viruses. The average annual mortality excess rate per 100,000 ranged from 11.6 to 41.2 with most of the influenza-associated deaths per year registered among the elderly. We estimate that at least 434 deaths associated with influenza occurred during the 2019-2020 season among children aged <18 years. We adjusted rates using the lowest multiplier from any season between 2010–2011 and 2017–2018. ... During seasonal influenza, mortality is concentrated in the very young and the elderly, whereas during flu pandemics, young adults are often affected at a high rate. Older adults also accounted for 75% of influenza-associated deaths, highlighting that older adults are particularly vulnerable to severe outcomes resulting from an influenza virus infection. Estimated Influenza Disease Burden – United States [1] US influenza statistics by flu season. (See Pediatric Influenza.) Hospitalization rates among children 0-4 years old and adults 18-49 years old were higher than observed during the 2009 H1N1 pandemic (6). This is unusual since influenza is typically most deadly to weak individuals, such as infants under age two, adults over age 70, and the immunocompromised . These testing data are often not available for up to 2 years after the end of a flu season, and thus the burden estimates are revised when additional testing data become available.

The methods used to calculate the estimates have been described previously (1-2). Select cause of death (ICD10 code search is available). 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. : +45 45 33 70 00 View the reporting rates of influenza-like illness (ILI) consultations from General Practitioners in Scotland technical document. To adjust for this, CDC collects data annually from participating FluSurv-NET sites on the amount of flu testing and the type of tests used at the site. The average annual mortality excess rate per 100,000 ranged from 11.6 to 41.2 with most of the influenza-associated deaths per year registered among the elderly. Read the review in the Weekly epidemiological record; Archives. In contrast, Japan and Taiwan had reported a mortality rate from influenza around 0.45% and 0.69% respectively, higher than the mortality rate collected from data in Chinese port cities, such as Hong Kong (0.25%), Canton (0.32%), and Shanghai. Burden estimates from the 2019–2020 season will be updated at a later date when data on contemporary testing practices become available. COVID-19: Many people infected with the coronavirus do not feel sick or have any symptoms at all, but they can still transmit the coronavirus to … Overall, influenza A(H1N1)pdm09 viruses were the most commonly reported influenza viruses this season. These estimates are subject to several limitations. There is a trade-off between timeliness and accuracy of burden of disease estimates. Influenza season 2019 ... are already seeing increased rates of influenza hospitalisation. Therefore, we used a mathematical model to estimate the total number of pediatric deaths based on hospitalization rates and the frequency of death in and out of the hospital using death certificates. For the past several years, CDC has used a mathematical model to estimate the numbers of influenza illnesses, medical visits, hospitalizations, and deaths (1-4). Estimates of influenza-associated mortality were of similar magnitude. This makes it difficult to directly compare our estimates since 2009 to those older reports, though the estimates from our current method are largely consistent for similar years12–15. To provide timely burden estimates to the public, clinicians, and public health decision-makers, CDC uses preliminary data that may lead to over- or under-estimates of the true burden. This burden was similar to estimated burden during the 2012–2013 influenza season1. However, the graph in section 6 of the Winter Excess Mortality report above indicates that the highest number of weekly deaths in the 2018 to 2019 period occurred in week 1 of 2019… At the national level, notifications of laboratory-confirmed inf… First, rates of influenza-associated hospitalizations are based on data reported to the Influenza Hospitalization Surveillance Network (FluSurv–NET) through September 2, 2020. CDC estimates that the burden of illness during the 2018–2019 season included an estimated 35.5 million people getting sick with influenza, 16.5 million people going to a health care provider for their illness, 490,600 hospitalizations, and 34,200 deaths from influenza (Table 1). Our finding that baseline respiratory mortality and access to he … View the retrospective 2017 to 2018 data. Why are these estimates lower than the preliminary in-season burden estimates last updated in April 2020? The highest age-specific mortality rate was observed in those aged 85 years and over, with 1,744.3 deaths per 100,000 people. Third, estimates of influenza-associated illness and medical visits are based on a ratio of illnesses to hospitalizations determined in a prior study. Division of Information, Evidence, Research and Innovation WHO Regional Office for Europe UN City Marmorvej 51 DK-2100 Copenhagen Ø Denmark Tel. Freedom of Information | Released on 24 February 2021 Deaths from influenza 2020 . Influenza B viruses were not commonly reported among circulating viruses during the 2018–2019 season. Figure 2 – Number of positive influenza tests and percentage of positive tests, by type, subtype and report week, Canada, weeks 2018-35 to 2019-34. No influenza-related excess mortality was seen among people 65 years and older, although a small peak in all-cause excess mortality was seen in week 1, 2019, in northern Sweden. CDC’s estimates of hospitalizations and mortality associated with the 2019–2020 influenza season show the effects that influenza virus infections can have on society. The pandemic mostly killed young adults. ... a fatality rate of 5.7 per cent. Weekly influenza updates for the period 2003 - 2013 Weekly electronic bulletins (2003-2009) The Weekly Electronic Bulletin was written by the European Influenza Surveillance Scheme Co-ordination Centre from the 2003–04 to the 2008–09 season. This web page provides estimates on the burden of influenza in the United States for the 2018–2019 influenza season. Comparing COVID-19 and 2020 influenza and pneumonia mortality rates, the largest absolute difference in rates was found in those aged 85 years and over, with a difference of 712.9 deaths per 100,000 people. Based on NCHS mortality surveillance data available on April 1, 2021, 11.4% of the deaths that occurred during the week ending March 27, 2021 (week 12), were due to pneumonia, influenza, and/or COVID-19 (PIC). There are 4 types of seasonal influenza viruses, types A, B, C and D. Influenza A and B viruses circulate and cause seasonal epidemics of disease.. The season had moderate severity based on levels of outpatient influenza-like illness, hospitalizations rates, and proportions of pneumonia and influenza-associated deaths. Differences: COVID-19 and the Flu Cause. The pathogen. The vast majority of influenza viruses detected were type A. *Some of the data used to calculate burden estimates are incomplete or not yet available. These multipliers are based on data from a prior season, which may not be accurate if patterns of care-seeking have changed. Select format (Excel or CSV for example) This will provide you with a dataset showing the number of deaths from influenza in 2019. CDC estimates that the burden of illness during the 2019–2020 season was moderate with an estimated 38 million people sick with flu, 18 million visits to a health care provider for flu, 400,000 hospitalizations for flu, and 22,000 flu deaths  (Table 1). Alltagssprachlich wird die Bezeichnung Grippe häufig auch für grippale Infekte, Erkältung oder Verkühlung verwendet, bei denen es sich aber um verschiedene andere, in der Regel deutlich harmloser verlaufende (insof… In addition to expected changes in available data on testing practices and patients hospitalized for flu, there were unexpected data delays due to the onset of the COVID-19 pandemic in Spring 2020. A CFR is the proportion of people diagnosed with a disease who die from the disease (cf. This report summarizes the 2018-2019 influenza season in the temperate regions of the northern hemisphere. 2020 weekly updates; 2019 weekly updates; 2018 weekly updates; 2017 weekly updates; 2016 weekly updates; 2015 weekly updates; 2014 weekly updates; … By combining data on hospitalization rates, influenza testing practices, and the frequency of death in and out of the hospital from death certificates, we estimate that there were approximately 480  deaths associated with influenza in children during 2018–2019. The current estimates were made using the highest testing rate for each age-group from the 2010-2011 through the 2017-2018 seasons. This report summarizes the 2018-2019 influenza season in the temperate regions of the northern hemisphere. Our global estimate of influenza-associated excess respiratory mortality is consistent with the 2017 estimate, despite a different modelling strategy, and the lower 2019 estimate which only captured deaths directly caused by influenza. To receive weekly email updates about Seasonal Flu, enter your email address: Centers for Disease Control and Prevention. Fifth, estimates of burden were derived from rates of influenza-associated hospitalization, which is a different approach than the statistical models used in older published reports. For these estimates, we included additional information to better capture flu testing practices at sites in the hospital-based surveillance system, FluSurv-NET, that collects data on patients hospitalized with laboratory-confirmed flu. Human mortality from H5N1 or the human fatality ratio from H5N1 or the case-fatality rate of H5N1 refer to the ratio of the number of confirmed human deaths resulting from confirmed cases of transmission and infection of H5N1 to the number of those confirmed cases. But news reports and the World Health Organization often estimate it at around 0.1%. But news reports and the World Health Organization often estimate it at around 0.1%. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. What is the typical peak month for influenza deaths? The case fatality rate for influenza will obviously change year to year. Hospitalization rate. Third, estimates of influenza-associated illness are made by multiplying the number of hospitalizations by the ratio of illnesses to hospitalizations; estimates of medical visits are made by a similar process. Poisson regression models permit the estimation of deaths associated with influenza A and B, but require robust viral surveillance data. leading cause and influenza and pneumonia, the ninth in 2019, switched ranks. Lost in the discussion about COVID-19 is the fact that the US is experiencing a severe influenza season that has already resulted in more than 16 000 deaths. up to week 40 2019, in 40.7% of GP practices in England, the provisional proportion of people who had received the 2019 to 2020 influenza vaccine … Activity began to decline in March, perhaps associated with community prevention measures for COVID-19 (5-6). This has led the Quarter 1 2019 mortality rate to be statistically significantly lower than all years, except 2014, which was a notably low year for mortality and had the same rate for all persons in 2019. The most updated crude rates of hospitalization for FluSurv-NET sites from the 2018–2019 season are available on FluView Interactive7. You will be subject to the destination website's privacy policy when you follow the link. COVID-19: Caused by the 2019 coronavirus, also known as SARS-CoV-2.. However, influenza-associated pediatric deaths are likely under-reported, as not all children whose death was related to an influenza virus infection may have been tested for flu (10,11). Publications. Influenza deaths in 2019 and 2020 . We adjusted rates using the most conservative multiplier from any season between 2010–2011 and 2016–2017. The 2019–2020 influenza season was atypical in that it was severe for children aged 0-4 years and adults 18-49 years where rates of infections, medically attended illnesses, hospitalizations, and deaths were higher than those observed during the 2017-2018 season, a recent season with high severity (7). This makes it difficult to directly compare our estimates for seasons since 2009 to those older reports, though the estimates from our current method are largely consistent with estimates produced with statistical models for similar years (12–13).
