Asymptomatic SARS Coronavirus Infection among Healthcare Workers, Singapore
Singapore, Keywords: asymptomatic SARS Coronavirus infection, SARS seroconversion, SARS epidemiology
We conducted a study among healthcare workers (HCWs) exposed to patients with severe acute respiratory syndrome (SARS) before infection control measures were instituted. Of all exposed HCWs, 7.5% had asymptomatic SARS-positive cases. Asymptomatic SARS was associated with lower SARS antibody titers and higher use of masks when compared to pneumonic SARS.
