Reveal the characteristics and regular pattern of its epidemic.①Investigated the epidemiological history of 448 clinical confirmed SARS cases, drawing the map of coming places of primary cases and whereabouts of the secondary cases, clarify the reasons of SARS inputting and spreading.②Exploring transmission relationship between cases by drawing the chain-map and learning the main transmission process.③Selecting the chain-cases with the exact onset and contact time to calculating the average incubation of same generation cases on different transmission chains and the average incubation of different generation cases on same transmission chain, Calculating the incubation median, the fifth percentile and the ninety-fifth percentile of the incubation of the observed cases.④Analyzing the timeliness of admission and the treating condition through the statistical calculation of the onset time, the admission time, the hospitalization time as well as the diagnostic time of the suspect and clinical confirmed cases.
