- * Refers to cases identified during the course of the outbreak. 4 of the 36 initially identified SARS cases during the outbreak did not have serological confirmation, and they were replaced by the 4 additional, previously unrecognized, seropositive individuals identified during the serosurvey (n = 36).
- † The case fatality rates among physicians, nurses from the general ward, and among staff with patient care duties are 50, 22, and 23%, respectively.
- ‡ Positive serologic results are listed as 'new' if the individual was not recognized as a symptomatic case during the outbreak, but was found to be seropositive during the course of this study.
- § Physicians cases include: Anesthetist/Anesthesiologist (3), General Practitioner (2), Pulmonary Specialist (1), Gynecologist (1), Orthopedic Surgeon (1). Radiologists are included in the 'Radiology' category.
- ¶ Nurses who were assigned to the general inpatient ward, or the intensive care unit/operating room are indicated, others not specifically assigned are grouped into a single category.
