| | WHO | Severe Acute Respiratory Syndrome (SARS) - multi-country outbreak - Update 27 |
 | | In SARS outbreaks, a “super-spreader” is a source case who has, for as yet unknown reasons, infected a large number of persons. |
 | | The SARS response is the roll out of a global alert and response activity under the revision of the International Health Regulations, which provide the legal framework for the surveillance and reporting of infectious disease and for the use of measures to prevent their international spread. |
 | | Outbreaks in the hotel and housing estate indicated that SARS was showing an unusual pattern of transmission in Hong Kong, probably involving an environmental component, that would place persons at risk outside the confined health care settings associated with outbreaks in most other countries. |
