Weekly U.S. Influenza Surveillance Report
Most important on the prevention list is getting a flu vaccine, as well as taking steps to stave off both the flu and COVID, such as hand-washing, social distancing, and wearing a mask. Learn. Flu activity is unusually low at this time. A case of human infection with a novel influenza A virus was reported this week. The virus was an influenza A(H1N1) variant (A(H1N1)v) virus. This season there have been three novel influenza A viruses reported – one A(H3N2)v virus and two A(H1N1)v viruses.
A description of the CDC influenza surveillance system, including methodology and detailed descriptions of each data component is available on the surveillance methods page. Additional information on the current and previous influenza seasons for flj surveillance component are available on FluView Interactive.
Seasonal influenza activity in the United States remains nwo than usual for this time of year. The percentage of respiratory specimens testing positive for influenza at clinical laboratories is 0. The number of influenza positives specimens reported by public health labs remains unusually low. During week 15, 1. Nationally, ILI remains below the national baseline of 2.
During week 15, all jurisdictions experienced minimal ILI activity. Because of the ongoing COVID pandemic, this system will suspend data collection for the influenza season. FluSurv-NET sites reported a current cumulative hospitalization rate of 0. This is above the epidemic threshold of 6. No influenza-associated pediatric deaths were reported to CDC this week.
The total for the season is one. The results of tests performed by clinical laboratories nationwide are summarized below. 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.
The results of tests performed by public health laboratories nationwide are summarized below. Aroynd performs genetic and antigenic characterization of U.
These data are used to compare how similar the currently circulating influenza viruses are to the reference viruses representing viruses contained in the current influenza vaccines and to monitor evolutionary changes that continually occur in kinc viruses circulating in humans.
CDC also tests susceptibility of influenza viruses to antiviral medications, including the neuraminidase inhibitors oseltamivir, zanamivir, and peramivir and the PA endonuclease inhibitor baloxavir. Virus characterization data will be updated later this season when a sufficient number of specimens have been tested. Please note, the U. Many people are accessing the healthcare system in alternative settings, which may or may not be captured as a part of ILINet. It is particularly important at aaround time to evaluate syndromic surveillance data, including that from ILINet, in the context of other sources of surveillance data to obtain a complete and accurate picture of both influenza and COVID activity.
Nationwide during week 15, 1. This percentage is below the fo baseline of 2. All regions reported percentages of outpatient visits for ILI below their region-specific baselines. Data from this subset of providers are used to calculate the percentages of patient visits for ILI by age group.
There has been an increasing trend among persons aged years, while the remaining age groups 5—24 years, 25—49 years, 50—64 years, and 65 years and older bow experienced a stable or slightly increasing trend. Differences what kind of flu is going around now the data presented here by CDC and independently by some health departments likely represent differing levels of data completeness with data presented by the health department likely being the more complete.
The geographic spread of influenza as reported by state and territorial epidemiologists indicates geographic spread of influenza viruses but does not measure the severity oc influenza activity. Due to the impact of COVID on Oof surveillance, and the fact that the state and territorial epidemiologists report relies heavily on ILI activity, reporting for this system will be suspended for the influenza season.
Data from previous seasons is available on FluView Interactive. Additional geographic spread surveillance information for current and past seasons: Surveillance Methods FluView Interactive. Between October 1,and April 17,FluSurv-NET sites in wbat states reported laboratory confirmed influenza hospitalizations for an overall cumulative hospitalization rate of 0.
This is much lower than average for kihd point in the season and lower than rates for any season since routine data collection began inincluding the noe severity season. The current rate is one-ninth the fpu at this time during the season. Hospitalization rates stratified by age will be presented if case counts increase to a level that produces stable rates by age.

This percentage is above the epidemic threshold of 6. The data presented are preliminary and may change as more data are received and processed.

Kajon and colleagues described the case of a year-old women from Rochester, New York, who was previously healthy but became infected in and quickly developed pneumonia and respiratory failure. During her hospital stay she suffered brain swelling and bleeding and stayed on a ventilator for more than a month.
There was also the case of a year-old Connecticut man infected in who had nausea, vomiting and chills. He spent days in the hospital with adenovirus infection.

There were so many outbreaks among new military recruits that the Department of Defense vaccinates personnel against two of the more serious strains with an oral vaccine.
Losing a loved one to viral pneumonia when you know it could have been prevented is hard. In the U. Adenovirus is not the killer that influenza is. Influenza kills 12, to 50, people a year in the United States alone, and puts up to , in the hospital. A cocktail of other viruses, from coronaviruses to rhinoviruses, also cause seasonal misery. And adenoviruses are very hard to kill. Reports indicate they can survive on plastic and metal surfaces— think countertops and hospital tables— for a month.
Some formulations of alcohol and chlorhexidine do not kill them easily, tests have shown, although chlorine does. IE 11 is not supported. For an optimal experience visit our site on another browser.
