Abstract：Objective To analyze the running status of China Infectious Diseases Automated-alert and Response System (CIDARS) in Zhaoqing City. Methods We descriptively analyzed the amount of signal, the proportion of signal response, signal response time, the manner of signal verification and signal response results of the diseases early-warned by mobile percentile method in Zhaoqing City during 2008-2014. The performance of CIDARS was evaluated by timeliness, sensitivity and the rate of false alarm, and the efficacy of early-warning on December 10, 2010 was compared between before and after adjusting the threshold value of CIDARS. Results A total of 5,708 early-warning signals were generated in Zhaoqing City during 2008-2014, and the response rate of the signals was 100.00%. The early-warning signals related to other infectious diarrhea (n=2,460, 43.10%), mumps (n=1,453, 24.56%) and influenza (n=664, 11.63%) prevailed. 11 signals involving 3 kinds of infectious diseases were preliminarily verified as the suspected outbreaks. 6 days were considered as the timeliness of the system, the sensitivity was 53.85%, and the rate of false alarm was 87.43%. After adjusting the threshold value of CIDARS, the rate of false alarm declined from 96.52% to 90.91%. The rates of false alarm regarding 5 infectious diseases, including other infectious diarrhea, dysentery, typhoid and paratyphoid, Japanese encephalitis and acute hemorrhagic conjunctivitis were decreased. Conclusions The running status of CIDARS in Zhaoqing City is normal. It has realized the timely early-warning signal response, but the efficacy remains to be further improved.
