"Initial data indicate that people who have become infected with omicron, as a rule, tolerate the disease more easily, but it is still too early to talk about this," RIA Novosti quoted Van Kerkhove as saying in an interview with CBS.
According to her, this may be caused by the early stages of infection of patients.
She added that it may take several weeks before it becomes clear how many patients with the new strain have developed severe stages.
Earlier it was reported that the new strain of the coronavirus "omicron" has not yet led to deaths.
