SARS-CoV Antibody Prevalence in All Hong Kong Patient Contacts	2004-09-17		.txt	text/plain	1927	69	42	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. Serologic surveys can be based on a random sample from the total population with appropriate stratification, on serum collected for other reasons (e.g., blood donors, all hospital admissions), or on surveys of persons who resided in sites of superspreading events or who have had close contact with a confirmed SARS patient. During the epidemic, close contacts were prospectively identified by the Hong Kong Special Administrative Region Government Department of Health through standardized telephone interviews with all 1,755 confirmed SARS patients within 1 week of hospital admission (February 15-June 22, 2003).	./cache/cord-310651-pxfwe67t.txt	./txt/cord-310651-pxfwe67t.txt
