Mild Illness Associated with Severe Acute Respiratory Syndrome Coronavirus Infection: Lessons from a Prospective Seroepidemiologic Study of Health‐Care Workers in a Teaching Hospital in Singapore

Abstract

Although the majority of cases of SARS are associated with pneumonia, a small number of mildly symptomatic individuals do seroconvert. HCWs who are exposed to patients with SARS can be infected with SARS, regardless of the intensity of exposure. This has implications for surveillance and infection control planning, in the event that SARS returns next winter.
