But the number of deaths and outpatient visits for flu or flu-like illnesses was down slightly from the week before, the CDC said in its weekly FluView report.
There were almost 26,000 new hospital admissions involving laboratory-confirmed influenza over those 7 days, up by over 31% from the previous week, based on data from 5,000 hospitals in the HHS Protect system, which tracks and shares COVID-19 data.
The cumulative hospitalization rate for the 2022-2023 season is 26.0 per 100,000 people, the highest seen at this time of year since 2010-2011, the CDC said, based on data from its Influenza Hospitalization Surveillance Network, which includes hospitals in select counties in 13 states.
At this point in the 2019-2020 season, just before the COVID-19 pandemic began, the cumulative rate was 3.1 per 100,000 people, the CDC’s data show.
On the positive side, the proportion of outpatient visits for influenza-like illness dropped slightly to 7.2%, from 7.5% the week before. But these cases from the CDC’s Outpatient Influenza-like Illness Surveillance Network are not laboratory confirmed, so the data could include people with the flu, COVID-19, or respiratory syncytial virus.
The number of confirmed flu deaths for the week of Nov. 27 to Dec. 3 also fell slightly from the last full week of November, 246 vs. 255, but the number of pediatric deaths rose from 2 to 7, and total deaths in children are already up to 21 for 2022-2023. That’s compared to 44 that were reported during all of the 2021-2022 season, the CDC said.
“So far this season, there have been at least 13 million illnesses, 120,000 hospitalizations, and 7,300 deaths from flu,” the agency estimated.
