What percentage of the risk of hospital admission with Omicron is lower compared to Delta? Great research reveals new numbers

The work says that people with Omicron’s disease are half as likely to be hospitalized than those in Delta. The risk of being placed in intensive care is reduced by about 75%, and the risk of death is over 90%.

Of the more than 52,000 victims of Omigran following this study, none needed life support, compared with 11 of the 17,000 affected by Delta.

In addition, Omicron was hospitalized for an average of 1.5 days, compared to approximately 5 days for Delta.

This analysis was conducted using data from the Kaiser Permanente organization of the California Hospital, and in December 2021, both types became widespread.

This data reinforces data collected from populations in South Africa or other countries in Great Britain. But, in animals or in the former vivo (outside the human body) – Omigron is more reflected in the upper respiratory tract (nose, throat) than in the lungs, where the covid forms begin acute -19.

The study, which has not yet been reviewed, was conducted by researchers at the University of California, Berkeley, Kaiser Permanent and Centers for Disease Control and Prevention (CDC).

“The study took into account important criteria such as age, gender, past SARS-CoV-2 infections, immunization status and comorbidities,” CDC Director Rochelle Walenski said Wednesday.

The results show that Omigran Delta is “less severe in nature”, and the study explains that people with higher immunity (after past infections or vaccinations) now catch it.

In addition, this work would have significantly reduced protection against severe forms of the disease if the effectiveness of the vaccines against infections associated with Omicron had been reduced.

After all, Ms. Valensky pointed out that Omigron’s epidemic had automatically led to a large number of hospital admissions, putting pressure on a care system whose staff had already been in trouble for two years.

The country currently reports an average of 750,000 new cases a day, and about 1,600 deaths daily.

More than 150,000 people are currently hospitalized with Covid-19 in the United States, a record.
