CDC twenty four seven. FluView: a weekly U.S. influenza surveillance report (CDC) 2019-20 Influenza Updates 11/22/19 - "It's Not too Late to Vaccinate" press conference held with health department and political leaders For week 29 this may cause the percent of P&I deaths to be higher than week 28 once more data are processed.While the percent of all deaths due to P&I has increased during weeks 9-13 (7.4-10.0%), the percent of all deaths with Influenza listed as a cause have decreased (from 1.0% to 0.7%) over this same time period. In the most recent three weeks, influenza A viruses are the most commonly reported influenza viruses in all age groups.CDC performs CDC CDC CDC also assesses * Six influenza viruses showed reduced or highly reduced inhibition by at least one neuraminidase inhibitor.
ILI is below baseline nationally and for all regions.One jurisdiction experienced high ILI activity this week compared to three jurisdictions that experienced high activity last week.No jurisdictions reported regional or widespread influenza activity this week.The overall cumulative hospitalization rate for the season increased to 69.2 per 100,000.The percentage of deaths attributed to pneumonia and influenza is 7.4%, down from 12.3% last week, but above the epidemic threshold of 6.7%.Four influenza-associated pediatric deaths occurring during the 2019-2020 season were reported this week. Weekly US Map: Influenza Summary Update - CDC. Data on patients admitted through April 30, 2020 will continue to be updated as additional information is received.The highest rate of hospitalization is among adults aged ≥ 65, followed by children aged 0-4 years and adults aged 50-64 years.Among 3,433 hospitalized adults with information on underlying medical conditions, 92.3% had at least one reported underlying medical condition, the most commonly reported were cardiovascular disease, metabolic disorder, obesity, and chronic lung disease. Differences in the data presented here by CDC and independently by some state health departments likely represent differing levels of data completeness with data presented by the state likely being the more complete.The influenza activity reported by state and territorial epidemiologists indicates geographic spread of influenza viruses but does not measure the severity of influenza activity.During week 24, the following influenza activity was reported:The Influenza Hospitalization Surveillance Network (FluSurv-NET) conducts all age population-based surveillance for laboratory-confirmed influenza-related hospitalizations in select counties in the Emerging Infections Program (EIP) states and Influenza Hospitalization Surveillance Project (IHSP) states.As in previous seasons, patients admitted for laboratory-confirmed influenza-related hospitalization after April 30, 2020 will not be included in FluSurv-NET. The total for the season is 174.Data from clinical laboratories (the percentage of specimens tested that are positive for influenza) are used to monitor whether influenza activity is increasing or decreasing. %PDF-1.7

The weekly Influenza Report may not have virologic surveillance data during this time. The Influenza Division at CDC collects, compiles and analyzes information on influenza activity year-round in the United States. AUSTRALIAN INFLUENZA SURVEILLANCE REPORT No. For the season, A(H1N1)pdm09 viruses are the predominant virus nationally. endstream

Centers for Disease Control and Prevention. 7, 2020 29 June to 12 July 2020 The Department of Health acknowledges the providers of the many sources of data used in this report and greatly appreciates their contribution. Influenza update - 370 22 June 2020 - Update number 370, based on data up to 07 June 2020.
* Influenza activity in NYC remains elevated. Four A(H1N1)pdm09 viruses showed highly reduced inhibition to oseltamivir and peramivir while showing normal inhibition to zanamivir. Nationally, for the season overall, influenza B viruses are the most commonly reported influenza viruses among persons 5-24 years, while influenza A viruses are the most commonly reported influenza viruses among persons 0-4 years and 25 years and older. This series of dynamic visualizations allow any Internet user to access influenza information collected by CDC’s monitoring systems.Data collected in ILINet are used to produce a measure of ILI(influenza like illness) activity* by state. Regional and state level data about circulating influenza viruses can be found on The predominant virus also varies by age group.
