A summary of presentations from the weekly Summit partner webinars
February 9 – The latest Summit Summary
Flu Surveillance Update – Alicia Budd (CDC)
Alicia Budd, MPH, Influenza Division, CDC, gave a Flu Surveillance Update through week four, ending January 28. (View slides.)
Virologic Surveillance – Percent Positive for Influenza
- Relatively calm
- Continuing to see flu activity decline
- Percent positivity continues to decline sharply nationally and in all the regions
- Viruses are almost exclusively influenza A (99.5%)
Virologic Surveillance – Virus Characteristics
- H3 predominance
- 76% H3
- 24% H1
- One virus was identified as having reduced inhibition to Oseltamivir this year (1 out of nearly 1,700)
- Not concerning
- Was susceptible to other influenza antiviral agents
Outpatient Respiratory Illness – people presenting to outpatient urgent care, primary practice, or emergency department for fever and cough or sore throat
- Numbers have dropped precipitously and are holding stable just above the national baseline
- For past several weeks, the two pediatric age groups (0-4 years, 5-24 years) are remaining stable, and the adults are continuing to slowly decline
- Most of country is seeing low levels of outpatient respiratory illness, with a couple of hot spots. However there are a lot of other respiratory viruses circulating in these areas that could be responsible for these infections
Long-term Care Facilities (LTCF) and Hospitals
HHS Protect – Percent of LTCF that reported at least one influenza positive test among residents
- Activity continuing to decline nationally and in all regions
- Hospitalizations continue to decline
FluSurv-NET – Age-specific information
- Cumulative rate of hospitalizations for the season as a whole:
- At a plateau nationally
- Approaching where U.S. was in the 2017–2018 season at this same time (recall that this was a severe influenza season)
- The 2017–2018 cumulative rate however, was still climbing at this time
- Currently, the cumulative rate is higher than any of the other seasons, but this is not likely to be true after this week
- Unless there is another wave, the nation won’t hit the severity in terms of hospital rates as the 2017–2018 season
Mortality – Percent of deaths from pneumonia, influenza, and COVID-19 (PIC)
- PIC deaths attributed to flu has been declining for the past few weeks
- The percentage of deaths due to flu has been declining for a couple of months
- COVID-19 deaths are also declining
- There have been 97 influenza-associated pediatric deaths
Preliminary In-Season Flu Burden Estimates, 2022–2023
- 25–49 million illnesses
- 12–23 million medical visits
- 280–600 thousand hospitalizations
- 17–53 thousand deaths
- Flu activity continues to decline across the country
- H3N2 remains the predominant virus
- Declining activity doesn’t mean no activity, so vaccination is still appropriate
- Surveillance continues year-round
- Upcoming meetings
- ACIP on February 22 – Interim VE estimates
- WHO’s Vaccine Consultation Meeting in Geneva – February 20–24
- The 2023 immunization schedules have been published.
- The 2023 NAIIS in-person annual meeting will be held on May 9–11, 2023, at the Atlanta Marriott Perimeter Center in Atlanta, GA. Persons needing the password to register for this invitation-only event may contact firstname.lastname@example.org.
- Summit awards will be presented at the May in-person meeting and NAIIS is taking nominations. We have two categories open:
- The “Immunization Neighborhood” Immunization Champion award recognizes efforts by individuals and organizations focused on improving COVID-19 and non-COVID-19 immunization rates through the engagement of the immunization neighborhood.
- The Laura Scott NAIIS Immunization Excellence Award for Outstanding Influenza Season Activities Campaign recognizes innovative activities related to seasonal influenza vaccination across the lifespan (pediatric, adolescent and/or adult activities) and/or among healthcare workers related to improving influenza vaccination.
- Immunize.org, with pain mitigation expert, Anna Taddio, PhD, will host a free, 1-hour webinar, Improving the Vaccination Experience: Reducing Pain and Anxiety for Children and Adults, on February 28 at 1:00 p.m. (ET). All are welcome to register!
