Influenza Surveillance Data from Beijing, 2015-2024

2,468,817 influenza-like illness (ILI) cases were analyzed from Chaoyang District, Beijing, China, spanning 2015 to 2024. The dataset, authored by Xing Gao and shared under a CC-BY-4.0 license, was last updated in May 2026. It likely contains records from multi-source surveillance including ILI cases, virological results, and reported influenza cases.

Use Cases

• Modeling influenza seasonality shifts based on the described 'increase-suppression-resurgence' pattern
• Analyzing age-stratified infection rates based on the reported rate ratios for children, adults, and seniors
• Tracking viral strain dominance over time based on the mention of B/Yamagata lineage absence
• Conducting interrupted time-series analysis based on the described GAMM-AR(1) modeling framework

Strengths

• Includes 2,468,817 ILI cases providing a substantial observational base
• Covers a 9-year time span from 2015 to 2024, capturing pre- and post-pandemic periods
• Uses multi-source surveillance data from a defined geographic area (Chaoyang District, Beijing)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The dataset is very small (12.3 KB), suggesting it may contain summary statistics or a document rather than raw case-level data
