-4.9% of cases were admitted.
-29% of those admissions were with severe disease.
-Median hospital stay was half that of Delta admissions.
-18% of admissions were in children, five times more than Delta wave.
-Omicron transmission rate meant that while less severe, the wave lead to nearly the same number of admissions as Delta wave, but in a shorter period of time.
Not much info on reasons why Omicron disease is less severe, but early data shows SA's very high level of Delta infections likely played a significant part.
