Timeliness Criteria for Infectious Disease Reporting and Review，Criteria for Data Quality Audit and Problem Identification in Infectious Disease Reporting Cards

From 2023 to 2024, the Huangpu District CDC in Guangzhou established refined quality control rules for a Python-based application, guided by the national specifications for infectious disease information management. These rules evaluate reporting and review timeliness, ID number validity, and data integrity for 11 key fields—including patient demographics (e.g., age, address, contact), case details (e.g., onset date, diagnosis, disease name), and classification information—to ensure data accuracy and logical consistency. This process begins with reporting by healthcare institutions through the national system, followed by review at the district/county CDC level
