American scientists have concluded that the Omicron strain not only causes less severe disease than other variants of coronavirus, but also provides a shorter period of hospitalization. In particular, such characteristics of this Covid-19 mutation was reported by an epidemiologist from the University of California at Berkeley and the author of the study Joseph Lewnard, New York Times reports.

"A new study of nearly 70,000 Covid patients in California demonstrates that Omicron causes less severe disease than other coronavirus variants, results that align with similar findings from South Africa, Britain and Denmark, as well as a host of experiments on animals," the message reads.

Compared to Delta, infection with Omicron caused hospitalization twice as rare. Of the more than 52,000 patients with the mutation registered with Kaiser Permanente in Southern California, none were connected to artificial ventilation of lungs.

"It’s truly a viral factor that accounts for reduced severity," Dr. Lewnard said.

Moreover, the people who were hospitalized with Omicron stayed there for a shorter time. The period of hospitalization with this type of virus lasted over three days less, or 70% less than in the case of Delta.

Fourteen patients with Delta infection died, while only one fatal case was reported with Omicron.

This allowed doctors to conclude that the risk of death with Omicron is 91% lower than other coronavirus variants.

When scientists gathered evidence that Omicron was less serious, they tried to understand why. One reason is that people infected with this strain have stronger immune defenses than in previous waves of the pandemic.

In addition, vaccination also counteracts the virus.

As it was reported, Head of the World Health Organization's European Regional Office Hans Kluge believes that more than 50% of the region's population will be infected with Omicron in the next six-eight weeks.

The Ministry of Health of Ukraine predicts a new wave of coronavirus at the end of January. According to the forecast of the Ministry of Health, the next outbreak will begin in late January, the peak will be in February with a gradual decrease until April.
