Predicting the Time-Varying Population Immunity and Importation Risk and Their Impact on Co-Circulation of Influenza and COVID-19 in Hong Kong

Manuscript under submission · target: Nature Human Behaviour · 2026

First Author

Manuscript Under Submission · target: Nature Human Behaviour — Benchmarks three Bayesian transmission models — fully mechanistic, semi-mechanistic, and purely statistical — against multi-source surveillance data to reconstruct 15 years of subtype-specific influenza immunity in Hong Kong and quantify a durable post-pandemic regime change in influenza–COVID-19 co-circulation.

Recommended citation: Chen, J., Wang, H., Wang, D., Lau, Y. C., Hossain, M. P., Ryu, S., Wu, P., Opatowski, L., Cowling, B. J., & Ali, S. T. (2026).
