Omicron appears to lead a milder illness for patients compared with previous COVID-19 variants. However, not all infected would describe their as mild. In this study, we investigate the experienced severity and symptoms of variant.We conducted nationwide cross-sectional including 5036 individuals ages, consisting reverse transcription-polymerase chain reaction confirmed SARS-CoV-2 cases from 1 January 31 2022 (n = 4506) control group without SARS-COV-2 infection in December 2021 or 530). was dominant during period. Cases were asked about acute answered web-based questionnaire 10-30 days after positive test while controls past week.Among cases, 97% reported at least one symptom phase 79% controls. Just over half assessed asymptomatic mild, whereas 46% moderate severe. Children fewer less severe illnesses than adults (P <0.001). The largest risk differences (RDs) between adult due observed fever (RD 60.6%, confidence interval [CI] 57.4-63.6), fatigue 49.6%, CI 44.1-54.7), chills 48.8%, 43.8-53.2).Most those experience symptoms, variant disease. does mean that an unprecedented rate infections worldwide leads urgent questions long COVID infections.
