Article Synopsis
- In early 2023, there was a notable global increase in XBB variants of COVID-19, while China experienced a significant outbreak linked to Omicron subvariants in late 2022 and early 2023.
- This study collected and analyzed over 56,000 sequences to understand the distribution of viral variants and how the dominance of imported cases impacted the prevalence of XBB in local populations.
- Findings revealed that XBB transitioned from being primarily imported to local cases starting in April 2023, showing varying patterns of dominance across different regions and a correlation between imported and local cases.
