SARS-CoV antibody prevalence in all Hong Kong patient contacts

Emerg Infect Dis. 2004 Sep;10(9):1653-6. doi: 10.3201/eid1009.040155.


A total of 1,068 asymptomatic close contacts of patients with severe acute respiratory (SARS) from the 2003 epidemic in Hong Kong were serologically tested, and 2 (0.19%) were positive for SARS coronavirus immunoglobulin G antibody. SARS rarely manifests as a subclinical infection, and at present, wild animal species are the only important natural reservoirs of the virus.
