To the Editor: Although a large number of health
care workers have been known to be infected with severe acute respiratory
syndrome (SARS), the incidence and the modes of infection within this population
have not been completely described.
We examined SARS infection rates among health care workers in the First
Hospital of Peking University, Beijing, China, a general hospital with 1147
beds, 29 clinical departments, and more than 2000 staff members. A total of
322 patients diagnosed with SARS were admitted to the hospital from March
24 through May 13, 2003. Diagnostic criteria for SARS were those of the World
Health Organization1; IgG tests with a SARS-specific
enzyme-linked immunosorbent assay found that 86% of these patients were positive
for SARS during the third week of onset and 99% were positive during the fifth
week. No other virological test was performed on these patients.
