This paper deals with Severe Acute Respiratory Syndrome (SARS) using statistical analysis methods. Based on the numbers of the confirmed cases and the suspected cases of Haidian district in Be ijing city, we first statistically analyze SARS epidemic situation of Haidian di strict with regard to region and population, respectively. Then using orthogonal designs, we investigate how some factors such as age, gender and occupation inf luence the confirmed cases and the suspected cases of Haidian district, and obta in that the group of students and civil servants from 21 to 50 years old is of t he highest disease ratio, which is completely consistent with epidemic situation of Haidian district. These results have been adopted by ″Haidian Government Em ergency Management Information Systems(HEMIS)″ for SARS treatment and preventio n. Finally we show the correlation between the daily increased confirmed cases a nd the daily confirmed cases transformed from the suspected cases in Beijing cit y.
