"To date, there are no cases of Omicron which are reported as having been hospitalised or died through routine reporting. As a result, it is not possible to compare the risk of hospitalisation or death with other variants. However, it should be noted that most of the cases have a specimen date that is very recent and that there is a lag between onset of infection and hospitalisation and death. Future updates will assess severe outcomes from Omicron cases against Delta cases from the same time period."
