The Influenza Hospitalization Surve illance Network (FluSurv-NETI conducts population-based surveillance for laboratory•confirmed influenza.associated hospitalizations in ch ildren (persons younger than 18
years) and adults . The current netwol1< covers over 70 counties in the 10 Emerging Infections Program (EIP) stales (CA, CO, CT, GA, MD, MN , NM, NY, OR, and TN) and three additional slales (Ml, OH, and
UT). The network represents approximately 9% of US population (-27 million people). Cases are identified by reviewing hospital, laboratory, and admission databases and infection control logs for patients
hospitalized during the influenza season with a documented positive influenza test (Le., viral cu lture, direct/indirect fluorescent antibody assay {DFNIFA), rapid influenza diagnostic test {RIOT), or molecular
assays includlng reverse transcripUon-polymerase chain reaction {RT-PCR)). Data gathered are used to esUmate age-specific hospitalization rates on a weekly basis, and describe characteristics of persons
hospitalized with associated influenza illn ess . Laboratory-confirmation is dependent on clin ician-ordered influenza testing. Therefore, the unadjusted rates provided are likely to be underestimated as
influenza-associated hospitalizations can be missed if influenza is not suspected and tested for. FluSurv-N ET hospitalization data are preliminary and subject to change as more data become available. All
incidence rates are unadjusted. Please use the following citation when referencing these data : EfluVlew: Influenza Hospitalization Surveillance Network, Centers for Disease Control and Prevention. WEBSITE.

Summary of Influenza Activity 2017-2018
•Very high influenza activity for the 2017-2018 season, and overall disease was considered to be severe
•Activity peaked in early January and stayed high through March
–Most states reported widespread activity simultaneously –Very low activity being reported this summer…
•H3N2 viruses predominated through the peak of the season with some H1N1 activity •Significant influenza B activity peaking in late February
– Predominantly B/Yamagata (contained in IIV4) •Egg adaptation of H3N2 an issue this season?

•Long-term care facilities had lower coverage (58.5%) than other facility types (hospitals at 82.6%).

• Up to 8X increased risk for influenza-associated complications, including death,particularly for those with co-morbidconditions**
• Increased risk for influenza-associated complications among postpartum women
• Risk highest during the first postpartum week

-
Some coverage thoughts •Influenza vaccination coverage appears to still be well below HP2020 targets
– No increase from the 2016-2017 coverage (waiting on final data) – Coverage in the 65 years and older population stagnant...– Coverage in the 19-64 years of age high risk adults still very low…– Significant disparities exist in the non-Hispanic, black and Hispanic adult populations…– Coverage in pregnant women has leveled off; a strong provider recommendation makes a difference – HCW coverage remains strong, except in LTCF!

How do we discuss Vaccine Effectiveness?
• Address vaccine effectiveness directly, early, and as needed, during season
• Communicate the variability and unpredictability of flu
• Acknowledge that flu vaccination is not a perfect tool, but it is the best way to protect against flu infection
• Communicate the benefits of flu vaccination • Flu vaccination can reduce flu illnesses, doctors’
visits, missed work and school due to flu, as well as prevent flu-related hospitalizations and deaths.

How do we discuss Vaccine Effectiveness?
• Be transparent regarding flu VE • Use caution when discussing “match”
– With a good match, flu vaccine can reduce the risk of having to go to the doctor for flu by about 60% among the overall population.
– This number may be higher for some groups of people and lower for others (e.g., older people with weaker immune systems)
• Use impact data and data over multiple years to provide perspective on vaccine benefits
• At all opportunities, continue to educate providers, partners and the public on the reasons people may get sick with ILI following flu vaccination.

More messaging on Vaccine Effectiveness…
•Questions about efficacy and duration remain – Do not base efficacy or duration of immunity discussions on one season but look collectively at multiple seasons – Vaccine in the patient is 50%-60% effective; vaccine on the shelf is 0% effective. – Season of 2014-2015 had about 62% vaccine effectiveness…
•And vaccine effectiveness should mot be measured by incidence alone
– Hospitalizations prevented – Medical visits prevented

Some communications thoughts •Vaccination also can reduce the risk of hospitalizations and deaths.
–vaccine preventable disability •Important benefits can be gained by increasing vaccination rates across all age groups with currently available vaccines.
•One CDC study* concluded that flu vaccination prevented an estimated 13.6 million flu cases, 5.8 million medical visit & nearly 113,000 flu-related hospitalizations in the United States over a 6-year period (2005-2011).
