SARS in Hong Kong : A Case Study of Virus Spreading in Social Community
Author(s): Huolin Xin

Subject(s): CX.1



Little world network model is used to study the dynamics of SARS (severe acute respiratory syndrome) spread in Hong Kong last year. Many forms of the spreading dynamics have been used in the stimulation and their representations in the result have been studied compared with the real data. It is found that, the form of discrete levels with exponential decay can describe the rate of infection which yields both qualitatively and quantitatively comparable result to the real data in Hong Kong. The discrete level with decay denotes the infectious reduction of SARS virus generation by generation. The intrinsic period phenomena in both the stimulation and the real data is found and its explanation of nonlinearity of the spreading dynamics is introduced.
