Sentinel Surveillance of Infectious Diseases among Chinese Medicine Practitioners (CMPs)
Weekly Update

This weekly update outlines the data provided by CMPs participating in the sentinel surveillance of infectious diseases. This update aims at informing the public of community-wide trends of infectious disease based on inference from the collected data, and does not represent the situation at any particular clinic or geographic area.

Methodology:   1. Sentinel CMPs at selected clinics record the total number of consultations and those fulfilling the case definition of disease conditions under surveillance. Records are sent to CHP on a weekly basis.   2. Disease conditions under surveillance by sentinel CMPs include: - Influenza-like illness (ILI) - Acute diarrhoeal diseases (ADD)   3. The CHP collects and collates data from all sentinel clinics weekly. The weekly consultation rate for each disease is generated by dividing the sum of cases reported by the CMPs by their sum of total number of consultations in the week.
