 (a) Epidemic curve of all 5327 cases of severe acute respiratory syndrome (SARS) in mainland China by date of onset from the first case on November 16, 2002, to the last on May 28, 2003, and by three locations. Other provinces including 449 cases from Shanxi, 282 from Inner Mongolia, 175 from Tianjin and 395 from other provinces, respectively. Date of onset was known for 5280 cases (99.1%) and the 47 missing values were obtained from imputation using date of admission to hospital, corrected for location and occupation (health care worker or not). Number of cases shows total number of new cases per day. For example, at the peak of the epidemic on April 23, 2003, the total number of new probable cases is 197, of which 129 cases are from Beijing, 14 cases are from Guangdong and 54 cases are from other provinces. (b) The distribution of probable SARS cases (n = 5327S) and population (n = 1292 million) by age group, in mainland China, in 2003.
