Separate figures from England, additionally printed Wednesday, present that the risk of needing to remain in hospital for sufferers with the brand new variant is 40% to 45% lower than in these with delta. This knowledge was additionally not peer reviewed.
Scientists stress that it’s nonetheless too early to definitively say whether or not omicron is milder, and its larger transmissibility means there may be nonetheless a risk that healthcare techniques might develop into overwhelmed as a result of the excessive quantity of infections will probably result in extra folks needing hospital care.
