As SARS is a diagnosis of exclusion, the status of a reported case may change over time. This means that previously reported cases may be discarded after further investigation and follow-up.

1. The start of the period of surveillance has been changed to 1 November 2002 to capture cases of atypical pneumonia in China that are now recognized as being cases of SARS.

2. National public health authorities report to WHO on the areas in which local chain(s) of transmission is/are occurring. These areas are provided on the list of Affected Areas.

3. The reporting period from Guangdong Province is from 16 November 2002 to 28 February 2003.

§ Due to differences in the case definitions being used at a national level, probable cases are reported by all countries except the United States of America, which is reporting suspect cases under investigation.
