The paper claims this is described in the ‘clinical hospital surveillance’ and although the report about that actually does not mention sequencing or Omicron there might be a clue as to why they don’t see data on omicron patients in ICU: https://covid-19.sciensano.be/sites/default/files/Covid19/COVID-19_Hospital_epidemiology_Part_1.pdf https://covid-19.sciensano.be/sites/default/files/Covid19/CO... Page 7: > Clinical outcomes, such as ICU admission or death, are only registered at hospital discharge […] > Furthermore, as ICU patients remain hospitalized for 2-3 weeks, their profile may only be available approximately 4 weeks after their initial hospital admission. To avoid misinterpretation of trends over time we do not report ICU data for the most recent 3 weeks.
