The U.S. CDC's Week #18 Influenza Surveillance Report published today indicates the number of hospital admissions with laboratory-confirmed influenza remained stable compared with the previous week.

On May 13, 2022, the CDC stated that among 1,775 hospitalized adults with information on underlying medical conditions, 93.7% had at least one underlying medical condition.

Hypertension, cardiovascular disease, metabolic disorder, and obesity are the most commonly reported.

And among 274 hospitalized children with information on underlying medical conditions, 67.5% had at least one, with the most commonly reported condition being asthma.

Separately, the National Center for Health Statistics (NCHS) Mortality Surveillance data available on May 12, 2022, shows that 7.2% of the deaths during week #18 were due to pneumonia, influenza, and/or COVID-19 (PIC).

Among the 1,425 PIC deaths reported for this week, 863 had pneumonia listed as an underlying or contributing cause of death on the death certificate, 533 had COVID-19, and 29 listed influenza.

This data indicates that current PIC mortality is due primarily to pneumonia, not COVID-19 or influenza.

The CDC says the 'data presented today are preliminary and may change as more data are received and processed.'

Even though the 2021-2022 flu season has been extended, the CDC recommends influenza vaccinations for most people over six months of age.

Flu shots remain available at most clinics and local pharmacies.
