Severe acute respiratory syndrome is a new disease that is highly contagious and is spreading in the local community and worldwide. This report is of a hospital medical officer with severe acute respiratory syndrome. He presented with sudden onset of fever, chills, myalgia, headache, and dizziness in early March 2003. He developed progressive respiratory symptoms and bilateral pulmonary infiltrates during the second week of his illness. Blood tests showed lymphopenia, mild thrombocytopenia, and prolonged activated partial thromboplastin time with normal d-dimer level. His chest condition gradually responded to ribavirin and corticosteroids, and serial chest X-ray showed resolving pulmonary infiltrates. The importance of early diagnosis lies in the potential for early treatment, leading to better response.

The severe acute respiratory syndrome (SARS) is a highly infectious respiratory disease, to the best of our knowledge caused by a hitherto unknown corona virus. The virus has spread from South East Asia to many countries of the world. Three case reports of patients from the Prince of Wales Hospital of The Chinese University of Hong Kong demonstrate typical clinical courses. Fever, cough, in most cases non-productive, myalgia, chills, and rigor are the leading symptoms. Leucopenia and thrombocytopenia are the most prominent laboratory parameters, increased values for lactatedehydrogenase (LDH) reflect a more severe clinical course. Advanced age and coexisting conditions seem to influence the prognosis unfavourably. The chest roentgenogram may be normal initially but at a later stage progressive consolidations in the majority of peripheral parts of the lung are observed, which cannot be differentiated from pneumonias of other origin. Even young patients can enter a stage of respiratory compromise rather fast. A therapy against the cause of the disease is not known. Empirical therapy with ribavirin in combination with high dose corticosteroids have proved successful. The disease may progress into respiratory failure comparable with an acute respiratory distress syndrome (ARDS). Mortality is around five to ten per cent. Stringent hygiene and quarantine measures are mandatory to prevent the further spread of this threatening disease.

Several cases of life threatening respiratory disease with no identifiable cause were reported from Guangdong Province, China; these were soon followed by reports from many other countries. The disease was named as severe acute respiratory syndrome (SARS). A novel coronavirus, isolated from the respiratory secretions of patients, has been implicated in the causation of SARS. The modes of transmission include droplet spread, close contact, and Fomites; shedding of virus from respiratory tract is the primary mode of transmission. SARS clinically presents with high-grade fever, chills and rigors, myalgia, headache, cough with or without sputum production, dyspnea, and dizziness. Chest radiographs reveal unilateral or bilateral, predominantly peripheral, areas of consolidation progressing with in a short time of bilateral patchy consolidation. Preliminary reports suggest a milder illness in young children. The case definition of probable SARS cases, laboratory investigations and precautions for prevention of spread are discussed.

The coronavirus that causes severe acute respiratory syndrome (SARS) is transmitted mainly via respiratory droplets. Typical presenting symptoms are akin to those of ordinary pneumonia. Young patients start with fever, chills, malaise, headache, or myalgia; cough and dyspnoea follow. Older persons and those taking corticosteroids may have neither fever nor respiratory symptoms. Exceptional suspicion is needed to identify SARS early in the illness. During an outbreak, even patients with low suspicion of SARS should be promptly isolated, and all contacts quarantined. Health workers need training in the use of appropriate barriers against droplets and other body fluids. Any fever cluster in patients or carers requires immediate action: discharges, visits, and transfers between wards and hospitals should be stopped. Halting hospital admissions and ten-day quarantine of suspected cases create wide buffer zones. To counter a possible resurgence of SARS, a system of prepared isolation and quarantine facilities is important.

Severe acute respiratory syndrome (SARS) is a new disease that poses a threat to international health. The SARS epidemic earlier this year affected more than 30 countries and regions, with a cumulative global total of 8098 cases. It is caused by a novel coronavirus, probably of animal origin. The mean incubation period is 6.4 days (range 2-11 days). Patients usually present with high fever, chills, myalgia and dry cough, with or without chest X-ray evidence of pneumonia at the onset of disease. A history of contact with or travel to an area with local transmission is common. Diagnosis is based on clinical criteria, as a valid rapid diagnostic test is not yet available. There is no specific antiviral therapy for this disease, and no controlled clinical trial for any treatment modality has been conducted. In several retrospective studies steroids have been shown to be useful in a proportion of patients who deteriorated despite antibiotics and supportive treatment. SARS has a high morbidity (about 25% required intensive care) and fatality (9.6%). A high index of suspicion for the disease, isolation of patients, strict observation of infection control practices and compliance with use of personal protective equipment are necessary to prevent nosocomial infection. Contact tracing and quarantine are essential measures to prevent community spread of disease. Prevention of future outbreaks requires strengthening of infection control practices in hospitals, development of a rapid diagnostic test and a vaccine, and removal of any animal reservoir and environmental conditions that led to the spread of the disease.

Severe acute respiratory syndrome (SARS) is a highly infectious disease with a significant morbidity and case fatality. The major clinical features include persistent fever, chills/rigor, myalgia, malaise, dry cough, headache and dyspnoea. Less common symptoms include sputum production, sore throat, coryza, dizziness, nausea, vomiting and diarrhoea. Older subjects may present with decrease in general well-being, poor feeding, fall/fracture and delirium, without the typical febrile response. Common laboratory features include lymphopenia with depletion of CD4 and CD8 lymphocytes, thrombocytopenia, prolonged activated partial thromboplastin time, elevated D-Dimer, elevated alanine transminases, lactate dehydrogenase and creatinine kinase. The constellation of compatible clinical and laboratory findings, together with the rather characteristic radiological features especially on HRCT and the lack of clinical response to broad-spectrum antibiotics, should quickly arouse suspicion of SARS. The positivity rates of urine, nasophargyngeal aspirate and stool specimen have been reported to be 42%, 68% and 97%, respectively, on day 14 of illness, whereas serology for confirmation may take 28 days to reach a detection rate above 90%. Recently, quantitative measurement of blood SARS CoV RNA with real-time RT-PCR technique has been developed with a detection rate of 80% as early as day 1 of hospital admission but the detection rates drop to 75% and 42% on day 7 and day 14, respectively.

Severe acute respiratory syndrome (SARS), caused by a highly infectious novel coronavirus (CoV), predominantly presents with severe pneumonitis leading to respiratory failure and death in approximately 10% of victims. Most cases present, after an incubation of 2 to 11 days, with fever and chills, which are followed by dry cough and dyspnea before the onset of respiratory failure. The management of SARS is controversial, largely due to the lack of data from controlled trials, which were logistically impossible to design or execute at the time of the overwhelming outbreak between March and June 2003. The use of an antiviral is logical although there is no effective agent against SARS-CoV, with the widespread use of ribavirin in 2003 attracting considerable scepticism. The use of ribavirin as a monotherapy in SARS is not recommended. Retrospective data suggest that administration of the anti-HIV drug Kaletra in combination with ribavirin could reduce mortality and incidence of respiratory failure. The use of corticosteroid was based on the similarity between SARS and bronchiolitis obliterans organizing pneumonia. Corticosteroid use is considered important in subsets of patients with SARS. As SARS may still resurge, it is imperative that past experience is analyzed. This review will attempt to address the rationale for pharmacotherapy in SARS using anecdotal and the limited published data.

Severe acute respiratory syndrome (SARS) is a newly emerged infectious disease with a significant morbidity and mortality. The major clinical features include persistent fever, chills/rigor, myalgia, malaise, dry cough, headache, and dyspnoea. Older subjects may present without the typical febrile response. Common laboratory features include lymphopenia, thrombocytopenia, raised alanine transaminases, lactate dehydrogenase, and creatine kinase. The constellation of compatible clinical and laboratory findings, together with certain characteristic radiological features and lack of clinical response to broad spectrum antibiotics, should arouse suspicion of SARS. Measurement of serum RNA by real time reverse transcriptase-polymerase chain reaction technique has a detection rate of 75%-80% in the first week of the illness.

Severe acute respiratory syndrome (SARS) is a newly emerged infectious disease with a significant morbidity and mortality. The major clinical features include persistent fever, chills/rigor, myalgia, malaise, dry cough, headache and dyspnoea. Respiratory failure is the major complication of SARS and approximately 20% of patients may progress to acute respiratory distress syndrome requiring invasive mechanical ventilatory support. However, the severity is much milder in infected young children. Treatment of SARS was empirical in 2003 due to our limited understanding of this new disease. Protease inhibitors (lopinavir/ritonavir) in combination with ribavirin may play a role as antiviral therapy in the early phase, whereas the role of IFN and systemic steroid in preventing immune-mediated lung injury deserves further investigation. Knowledge of the genomic sequence of the SARS coronavirus has facilitated the development of rapid diagnostic tests. In addition, other antiviral treatment, RNA interference, monoclonal antibody, synthetic peptides, and vaccines are being developed. This paper provides a review of the epidemiology, clinical features and possible treatment strategies of SARS.

Severe acute respiratory syndrome (SARS) is a serious respiratory illness caused by a novel human coronavirus. The disease is highly infectious and carries significant mortality and morbidity. There was a major outbreak of SARS in Guangdong, Taiwan, Beijing, Hong Kong and Toronto between March and June 2003. Common presenting features of SARS are high fever, chills, rigor, malaise, nonproductive cough, lymphopenia and pulmonary infiltrates, followed by rapidly progressive respiratory failure in some cases. We describe two patients with systemic lupus erythematosus (SLE) who presented with fever, systemic upset and pulmonary infiltrates between April and June, 2003. One patient was confirmed to have coronavirus pneumonia while the other had active SLE with lung involvement. Our cases illustrate the difficult diagnostic dilemma in the evaluation of febrile SLE patients during the SARS epidemic.
