New Study: COVID-19 Omicron Variant Is More Deadly Than the Seasonal Flu

Recent research suggests that adults hospitalized with the Omicron variant of SARS-CoV-2 have a higher death rate than those with seasonal influenza, despite Omicron being less virulent than Delta and Alpha strains. This higher death rate may be due to Omicron patients being older with more underlying illnesses and lower COVID-19 vaccination rates.

During the 2021-2022 flu season, patients who were hospitalized with the flu had a 55% lower likelihood of dying within 30 days compared to those who were hospitalized with the COVID-19 Omicron variant.

According to new research being presented at the European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) in Copenhagen, Denmark, adults who are hospitalized with the SARS-CoV-2 Omicron variant have a higher death rate compared to those hospitalized with seasonal influenza. This is despite the fact that the Omicron strain is considered less virulent, with lower case fatality rates compared to the delta and alpha strains.

According to the study by Dr. Alaa Atamna and his colleagues from the Rabin Medical Center at Belinison Hospital in Israel, adults (18 years or older) who were hospitalized with influenza during the 2021-2022 season were 55% less likely to die within 30 days compared to those hospitalized with the Omicron variant.

Influenza and COVID-19 are both respiratory diseases with similar modes of transmission. In

In December 2021, influenza re-emerged in Israel after it went undetected since March 2020. At the same time, the Omicron had substituted Delta as the predominant variant. But data directly comparing Omicron with seasonal influenza are scarce.

To find out more, researchers compared the clinical outcomes of patients hospitalized with COVID-19 (Omicron variant) and those hospitalized with influenza at a large academic hospital in Israel.

Consecutive patients hospitalized with laboratory-confirmed COVID-19 (167 patients; average age 71 years, 58% male) and influenza infection (221 patients; average age 65 years, 41% male) during December 2021 and January 2022 were included in the study.

Overall, 63 patients died within 30 days—19 (9%) were admitted with influenza and 44 (26%) were hospitalized with Omicron.

Patients with Omicron tended to have higher overall comorbidity scores, needed more assistance performing activities of daily living (e.g., washing and dressing), and were more likely to have high blood pressure and diabetes, whereas asthma was more common in those hospitalized with influenza (see table 1 in notes to editors).

Respiratory complications and the need for oxygen support and mechanical ventilation were also more common in Omicron cases than in seasonal influenza.

“A possible reason for the higher Omicron death rate is that patients admitted with Omicron were older with additional major underlying illnesses such as diabetes and chronic kidney disease,” says Dr. Atamna. “The difference might also be due to an exaggerated immune response in COVID-19, and that vaccination against COVID-19 was far lower among patients with Omicron.”

He continues, “The double whammy of overlapping influenza and COVID-19 epidemics will increase the complexity of disease and the burden on health systems. There is one basic step people can take that may alter the trajectory of either epidemic, get the vaccines for flu and COVID-19, especially if you are older and have underlying illnesses.”

The authors point out that the study was observational so can’t prove causation, and it was conducted in one hospital in Israel so the results may not apply to other countries and populations. And they cannot rule out the possibility that other unmeasured factors such as influenza and COVID-19 vaccination status may have influenced the results. They also note that the excess mortality observed for Omicron could be the result of an influenza season that was less severe than usual. Finally, the study included only hospitalized patients, so could not estimate the proportion of hospitalized patients in the total number of infected patients.

    Thank u

  3. Meaningless research unless eventually reveals the percentage of the fatalities which occurred among the “vaccinated” compared with those who somehow avoided rolling up their sleeves. It is now an open secret that the frankenjabs systematically degrade the immune system (hence, among other detrimental consequences, an obvious yet studiously ignored explanation for the phenomenon known as long Covid). What is less well know, since the truth is about the “pandemic” is far too hot for the Establishment/Big Pharma- captured mainstream media to handle, are details of the conspiracy between corporate, military and political players in the U.S. and elsewhere which have led to this devastating bioweapons attack on humanity, masquerading as a public health emergency. Anyone, the Danish researchers included, who wishes to understand what has really been going on for the last three years, should listen in to this conversation between two intrepid “pandemic” investigators, one of whom could become the next President of the United States. Gob-smacking stuff, backed by deep research and incriminating documentation.

  4. Don’t listen to what Michael, he’s a conspiracy nut
