- The SARS-CoV-2 Omicron (B.1.1.529) variant has been associated with lesssevere acute disease, however, concerns remain as to whether long-termcomplaints persist to a similar extent as for earlier variants. Studying 1 323 145persons aged 18-70 years living in Norway with and without SARS-CoV-2infection in a prospective cohort study, we found that individuals infected withOmicron had a similar risk of post-covid complaints (fatigue, cough, heartpalpitations, shortness of breath and anxiety/depression) as individualsinfected with Delta (B.1.617.2), from 14 to up to 126 days after testing positive,both in the acute (14 to 29 days), sub-acute (30 to 89 days) and chronic post-covid (≥90 days) phases. However, at ≥90 days after testing positive, indivi-duals infected with Omicron had a lower risk of having any complaint (43 (95%CI = 14 to 72) fewer per 10,000), as well as a lower risk of musculoskeletal pain(23 (95%CI = 2-43) fewer per 10,000) than individuals infected with Delta. Ourfindings suggest that the acute and sub-acute burden of post-covid complaintson health services is similar for Omicron and Delta. The chronic burden may belower for Omicron vs Delta when considering musculoskeletal pain, but notwhen considering other typical post-covid complaints.

- Introduction: SARS-CoV-2 infection causes acute COVID-19 and may result in post-COVID syndrome (PCS). We aimed to investigate how clinicians diagnose PCS and identify associated clinical and demographic characteristics.Methods: We analysed multiregistry data of all SARS-CoV-2 test-positive individuals in Sweden (n=1 057 174) between 1 February 2020 and 25 May 2021. We described clinical characteristics that prompt PCS diagnosis in outpatient and inpatient settings. In total, there were 6389 individuals with a hospital inpatient or outpatient diagnosis for PCS. To understand symptomatology, we examined individuals diagnosed with PCS at least 3 months after COVID-19 onset (n=6389) and assessed factors associated with PCS diagnosis.Results: Mechanical ventilation correlated with PCS (OR 114.7, 95% CI 105.1 to 125.3) compared with no outpatient/inpatient contact during initial COVID-19. Dyspnoea (13.4%), malaise/fatigue (8%) and abnormal pulmonary diagnostic imaging findings (4.3%) were the most common features linked to PCS. We compared clinical features of PCS with matched controls (COVID-19 negative, n=23 795) and COVID-19 severity-matched patients (COVID-19 positive, n=25 556). Hypertension associated with PCS cohort (26.61%) than in COVID-19-negative (OR 17.16, 95% CI 15.23 to 19.3) and COVID-19-positive (OR 9.25, 95% CI 8.41 to 10.16) controls, although most individuals received this diagnosis before COVID-19. Dyspnoea was the second most common feature in the PCS cohort (17.2%), and new to the majority compared with COVID-19-negative (OR 54.16, 95% CI 42.86 to 68.45) and COVID-19-positive (OR 18.7, 95% CI 16.21 to 21.57) controls.Conclusions: Our findings highlight factors Swedish physicians associate with PCS.
