BACKGROUND Surveillance is a critical component of epidemiological and public health practice,playing a significant role in the prevention,control,and management of major public health risks(1).Historically,surveillance methods were primarily based on hospital data(e.g.,sentinel hospital monitoring for influenza)or specific populations[such as the human immunodeficiency virus/acquired immunodeficiency syndrome(HIV/AIDS)population]for sentinel surveillance.
