Extensive studies from Britain and South Africa have previously suggested similar results.
Washington. A study in the United States on a sample of 70,000 patients My corona virus showed that in the case of infection with the variant Omicron The probability of hospitalization was reduced compared to the variant delta by half, the probability of hospitalization in an intensive care unit by three-quarters and the probability of death by up to 90%. Taser obtained this information from a report published by Agence France-Presse.
Of the 50,000 people with omicron, none required artificial pulmonary ventilation.
The median length of hospital stay using the omicron variant was only one and a half days. It was five days in the delta.
Up to 90 percent of Omicron patients are discharged from hospital within three days.
The British came to similar conclusions
The search was conducted in the Kaiser Permanente Medical Network in Southern California from December 1 to January 2. It was attended by researchers from the University of California, Berkeley, Kaiser Permanente and the Centers for Disease Control and Prevention (CDC).
Similar conclusions have previously been suggested by extensive studies from Britain and From the Republic of South Africa.
In vitro research on animals and cells has found that omicrons replicate better in the upper respiratory tract than in the lungs, which explains the easier course of the disease.
Vaccines protect against omicron
A non-peer-reviewed study in California, according to CDC Director Rochelle Walinska, took into account criteria such as age, gender, previous SARS-CoV-2 infection, vaccination and comorbidities.
According to the study, “Omicron is per se less severe than delta,” with a lower number of severe cases not just related to high vaccinations and infertility.
The study also indicates that the current Vaccines It is less effective against omicron, but continues to be highly protective against severe COVID-19 disease.
Despite the encouraging results of the research, Walenská urges caution, as omicron is overburdening the health care system due to the high rate of infection.
In the United States, there are now an average of three-quarters of new cases per day, about 150,000 hospitalizations and 1,600 deaths linked to the virus.
