Modelling input-output flows of severe acute respiratory syndrome in mainland China.

ABSTRACT:

Background

Severe acute respiratory syndrome (SARS) originated in China in 2002, and it spread to 26 provinces in mainland China and 32 countries across five continents in a matter of months. This outbreak resulted in 774 deaths. However, the spatial features and potential determinants of SARS input-output flows remain unclear.

Methods

We used an adjusted spatial interaction model to examine the spatial effects and potential factors associated with SARS input-output flows.

Results

The presence of origin-based spatial dependence positively affected SARS input-output flows from the neighbours of the origin regions. Two components of the input-output flows, migrant and hospitalization flows, exhibited distinctive features. The origin-based and destination-based spatial d
