Reconstruction of the Infection Curve for SARS Epidemic in Beijing, China Using a Back-Projection Method.

The infection curve of Severe Acute Respiratory Syndrome (SARS) using the back-projection method was reconstructed for the SARS outbreak period (from March 1, 2003 to June 20, 2003) in Beijing to assess the effectiveness of the intervention measures. There were 2,521 confirmed SARS cases with a population size of 13 million. The SARS outbreak pattern corresponded well with the major events timeline over the SARS outbreak. Despite the limited resources with such a large population size, the intervention measures taken by the Beijing Municipal Government seemed to be effective in containing the SARS epidemic in Beijing.
