During early weeks of the outbreak, about 8% of the health care assistants, 5% of the doctors, and 4% of the nurses got SARS. Most hospital workers were infected from direct contact with patients with SARS; most of those patients were in general wards and had not been suspected of having the disease. All infected hospital workers said they had used masks when caring for patients. Many hadn't used gowns, gloves, or eye shields. Infected hospital workers were identified quickly, usually within 2 to 3 days of developing symptoms. None infected their own families or close friends.
