SARS • The initial symptoms are non-specific and common. • Incubation period of 2~10 days allowing the infectious agent to be transported, unsuspected and undetected, in an air traveller from one city in the world to anyother city having an international airport. The concentration of cases in previously healthy adults and the proportion of patients requiring intensive care are particularly alarming.Intra-hospital transmission amplified regional outbreaks and augmented spread of the illness into the community.
