The researchers analyzed the medical records of 69,279 patients at Kaiser Permanente of Southern California who tested positive for COVID-19 from Nov. 30 to Jan. 1. Three-quarters were infected with the highly transmissible omicron variant, and the rest by delta.
The analysis found there was a 53% reduction in symptomatic hospitalization, a 74% reduction in admission into intensive care units and a 91% reduction in deaths — one from omicron compared to 14 from delta.
No patients with omicron required mechanical ventilation, compared to 11 cases with delta infections. And those who were hospitalized with the omicron variant had shorter hospital stays — a median of 1.5 days versus five days.
Reductions in disease severity were evident among both vaccinated and unvaccinated patients, the researchers found.
