(Asian News Hub) – Omicron infections are associated with a 91% reduction in risk of death compared to the Delta variant, CDC Director Rochelle Walensky said on Wednesday (Jan. 12), citing a new Kaiser Permanente Southern California study that looked at 52,297 Omicron cases and 16,982 Delta cases in California between November 30 and January 1.
The study, which is yet to be peer reviewed, also showed that Omicron infections were also associated with a 74% reduction in risk of going to the ICU, as well as a 53% reduction in risk of being hospitalized, Walensky said. No patients with Omicron required mechanical ventilation.
Additionally, those with Omicron had a shorter duration in hospital stay compared to Delta patients: “The duration of hospital stays was approximately 70% shorter, with the median of stays being 1.5 days for Omicron, compared to about five days for Delta,” Walensky said.
