Associations of Symptoms with and , Host Status, and Clinical Outcomes: A Registry-Based Observational Study in Sapporo, Japan

- BA.5 infection associated with higher symptom burden than BA.2
- Omicron breakthrough-infected individuals with ≥ 3 vaccinations or previous infection were less likely to exhibit systemic symptoms, but more likely to exhibit upper respiratory symptoms.
