Methods Data of SARS cases reported from the Beijing Municipal Centers for Disease Prevention and Control (BCDC) were collected and analyzed by descriptive epidemiology. Results In the early epidemic period, the intervals between the disease onset and the hospital admission seemed irregular, so was the intervals between the hospital admission and the notification. After the middle ten days of April, the intervals turned out to be more regular, and the disordered situation in terms of the hospital admission and the case notification was gradually brought under control. Conclusions Public health interventions against SARS has revealed positive impacts on SARS control program in Beijing. The timing and sensitivity of epidemic information reporting systems has been greatly improved in Beijing as a result of successful fight against this disease.展开更多

Methods Data of SARS cases notified from the Beijing Municipal Center for Disease Control and Prevention (BCDC) and supplemented by other channels were collected. All the data were analyzed by descriptive epidemiology. Results ①The number of probable cases with contact history was significantly higher than the excluded cases. ②The proportion of probable cases with contact history descended with epidemic development, but this situation did not occur in health care workers (HCWs). ③The fatality rate of probable cases with contact history was significantly higher than the cases without contact history (OR=1.489). ④The proportion of probable cases with contact history was 85.86% among health care workers, which was significantly higher than that of non-health care workers (85.86% v.s. 56.44%, OR=4.69). Conclusions ①The susceptible persons with contact history may not get infected, and the contact history is just a sufficient condition of infecting SARS; ②There are 3 conceivable reasons for the descending trend of the proportion in probable cases with contact history; ③The contact history is one of the risk factors of the death of SARS cases; ④The risk of contacting with SARS among health care workers is approximately 5 times higher than that of non-HCWs.展开更多
