Conclusion - Authority in the Chinese Border Regime

To contextualize recent developments, this book demonstrates how the Chinese border regime operates, specifically by differentiating its strategies of control according to a subject's geographic location (graduated sovereignty) and immigrant group (graduated citizenship). Following Ong, governmentality is shown to be territorialized in literal zones of exception. Further, the book demonstrates how authority over state territory is graduated: the regime rearticulates the border on both a regional and a local scale through establishing Special Border Zones that provide preferential policies, exceptional immigration procedures, and additional resources to integrate the local economy and facilitate crossborder trade. The border regime can also be shown to create metaphorical zones of exception if the border is understood as biopolitical as well as geopolitical.

An Outbreak of Human Coronavirus OC43 Infection and Serological Cross-reactivity with SARS Coronavirus

Background: In summer 2003, a respiratory outbreak was investigated in British Columbia, during which nucleic acid tests and serology unexpectedly indicated reactivity for severe acute respiratory syndrome coronavirus (SARS-CoV). Methods: Cases at a care facility were epidemiologically characterized and sequentially investigated for conventional agents of respiratory infection, SARS-CoV and other human CoVs. Serological cross-reactivity between SARS-CoV and human CoV-OC43 (HCoV-OC43) was investigated by peptide spot assay. Results: Ninety-five of 142 residents (67%) and 53 of 160 staff members (33%) experienced symptoms of respiratory infection. Symptomatic residents experienced cough (66%), fever (21%) and pneumonia (12%). Eight residents died, six with pneumonia. No staff members developed pneumonia. Findings on reverse transcriptase-polymerase chain reaction assays for SARS-CoV at a national reference laboratory were suspected to represent false positives, but this was confounded by concurrent identification of antibody to N protein on serology. Subsequent testing by reverse transcriptase-polymerase chain reaction confirmed HCoV-OC43 infection. Convalescent serology ruled out SARS. Notably, sera demonstrated cross-reactivity against nucleocapsid peptide sequences common to HCoV-OC43 and SARS-CoV. Conclusions: These findings underscore the virulence of human CoV-OC43 in elderly populations and confirm that cross-reactivity to antibody against nucleocapsid proteins from these viruses must be considered when interpreting serological tests for SARS-CoV.
