SAS 9.2 software was adopted in data analyses.
Results Of all the participants aged averagely 33.04 ± 7.40 years, 48.05% (37) were males and 35.06% (27) were full-time online manager of CIDARS. The average years of working for online management of CIDARS was 3.98 years. There were 77.92% and 84.41% of the participants reporting a consumption of ≤ 10 minutes each day to deal with single case and spatial-temporal early warning signals, 79.22% of the participants considering that CIDARS has played a role in infectious disease control and prevention, and 63.64% of the participants believing that the threshold values for early warning need to be modified according to local prevalence characteristics of infectious diseases, and 70.13% of the participants not acquiring general knowledge on the principle for early warning of the CIDARS, respectively.
