Abstract excerpt

The 2022/2023 season witnessed a rapid resurgence of H1N1pdm09 in Anhui Province, China, surpassing previous years, prompting an examination of hemagglutinin (HA) gene mutations and cross-immunity in this study. Anhui Province's surveillance data established the detection threshold for H1N1pdm09 using the Moving Epidemic Method. Joinpoint regression compared weekly percent change (WPC) rates. A total of 103...
