OBJECTIVE An outbreak of severe acute respiratory syndrome (SARS) occurred in the greater Toronto area between February and June 2003. We describe the clinical, laboratory, and epidemiologic features of children who were admitted to the Hospital for Sick Children, Toronto, with a presumptive diagnosis of suspect or probable SARS. METHODS A prospective investigational study protocol was establ...
Severe acute respiratory syndrome (SARS) is a new infectious disease caused by a novel coronavirus that leads to deleterious pulmonary pathological features. Due to its high morbidity and mortality and widespread occurrence, SARS has evolved as an important respiratory disease which may be encountered everywhere in the world. The virus was identified as the causative agent of SARS due to the ef...
Previous reports have indicated that patients with severe acute respiratory syndrome (SARS)–associated coronavirus infection could develop atypical pneumonia with fulminant pulmonary edema. However, the target cells of SARS viral infection have not been characterized in detail. We report the pathologic findings of the lung in 3 cases of SARS. Chest radiographs at 2 to 3 weeks of infection revea...
A new human coronavirus (hCoV-EMC) has emerged very recently in the Middle East. The clinical presentation resembled that of the severe acute respiratory syndrome (SARS) as encountered during the epidemic in 2002/2003. In both cases, acute renal failure was observed in humans. HCoV-EMC is a member of the same virus genus as SARS-CoV but constitutes a sister species. Here we investigated whether...
BACKGROUND Accurate, objective models of triage for patients with suspected severe acute respiratory syndrome (SARS) could assess risks and improve decisions about isolation and inpatient treatment. OBJECTIVE To develop and validate a clinical prediction rule for identifying patients with SARS in an emergency department setting. DESIGN Retrospective analysis using a 2-step coefficient-based...
OBJECTIVE To ascertain the prevalence of subclinical severe acute respiratory syndrome-coronavirus (SARS-CoV) infection and study the transmission of SARS-CoV in a local outbreak at a residential care home for the elderly. DESIGN Cross-sectional study. SETTING A residential care home for the elderly in Hong Kong with a local outbreak of SARS. PARTICIPANTS Residents and staff in the reside...
Severe acute respiratory syndrome-associated coronavirus (SARS-CoV) is a newly identified member of the family Coronaviridae and poses a serious public health threat. Recent studies indicated that the SARS-CoV viral spike glycoprotein is a class I viral fusion protein. A fusion peptide present at the N-terminal region of class I viral fusion proteins is believed to initiate viral and cell membr...
The severe acute respiratory syndrome (SARS) pandemic caught the world by surprise in 2003 and spread rapidly within a relatively short period of time. Hence, randomised placebo-controlled clinical trials on the treatment of SARS were not possible. Our understanding was obtained from observational, cohort studies, case series and reports. Nevertheless, such information is useful in providing cl...
The severe acute respiratory syndrome coronavirus (SARS-CoV) encodes proteins required for RNA transcription and genome replication as large polyproteins that are proteolytically processed by virus-encoded proteinases to produce mature replicase proteins. In this report, we generated antibodies against SARS-CoV predicted replicase protein and used the antibodies to identify and characterize 12 ...
There were three episodes of severe acute respiratory syndrome (SARS) (including one pandemic) in China from 2003 to 2004. Starting from 2002, we are also aware of the increasing alert of an avian flu pandemic. Epidemics of SARS and avian flu have posed huge threats to social stability, economic prosperity and human health in this country. Our experience during the SARS outbreaks can be of grea...
