The epidemic of severe acute respiratory syndrome (SARS) has now been brought under control and entered the so-called post-SARS stage, with only a very few new cases reported daily throughout China. As an infectious disease spreading through the respiratory tract, SARS is featured by the inconsistency between its clinical representations, physical signs of the lungs and chest imaging findings. It has been shown that atypical pneumonia (AP), with similar clinical features to SARS, has been identified in Guangzhou, China, long before the prevalence of SARS, a fact that urges further understanding of SARS in regard to its incidence and variable clinical courses, for its differential diagnosis with such diseases as AP, influenza-related pneumonia, pulmonary tuberculosis, fungal and cytomegalovirus pneumonia. Information sharing among the medical institutes and training of the first-line medical staff for their better understanding and awareness of SARS and AP is crucial in the clinical practice, to insure timely case identification and avoid "oversensitive" diagnosis. Consultation of particular cases involving experts from multiple medical science fields should be encouraged, which is also an effective measure against newly emerged infectious diseases.

Severe acute respiratory syndrome (SARS) is a viral disease, observed primarily in Southern China in November 2002, with variable flu-like symptoms and pneumonia, in approx. 5% leading to death from respiratory distress syndrome (RDS). The disease was spread over more than 30 states all over the globe by SARS-virus-infected travelers. WHO and CDC received first information about a new syndrome by the end of February 2003, after the first cases outside the Republic of China had been observed. A case in Hanoi, Vietnam, led to the first precise information about the new disease entity to WHO, by Dr. Carlo Urbani, a co-worker of WHO/Doctors without Borders, who had been called by local colleagues to assist in the management of a patient with an unknown severe disease by the end of February 2003. Dr. Urbani died from SARS, as did many other health care workers. In the meantime, more than 7,000 cases have been observed worldwide, predominantly in China and Hong Kong, but also in Taiwan, Canada, Singapore, and the USA, and many other countries, and more than 600 of these patients died from RDS. Since the beginning of March 2003, when WHO and CDC started their activities, in close collaboration with a group of international experts, including the Bernhard-Nocht-Institute in Hamburg and the Department of Virology in Frankfurt/Main, a previously impossible success in the disclosure of the disease was achieved. Within only 8 weeks of research it was possible to describe the infectious agent, a genetically modified coronavirus, including the genetic sequence, to establish specific diagnostic PCR methods and to find possible mechanisms for promising therapeutic approaches. In addition, intensifying classical quarantine and hospital hygiene measures, it was possible to limit SARS in many countries to sporadic cases, and to reduce the disease in countries such as Canada and Vietnam. This review article summarizes important information about many issues of SARS (May 15th, 2003).

The mysterious severe acute respiratory syndrome (SARS) that has originated from the southern Chinese province of Guangdong appears to be a major public health threat and medical challenge. Laboratory studies of SARS patients in a number of countries identified the etiologic agent being a novel member of coronaviridae. High RNA concentrations of this virus in sputum make it as a highly infectious agent. Low concentrations of viral genome are also detectable in feces. Coronaviruses are ubiquitos. They cause disease in many animals including pigs, cattle, dogs, cats, and chickens. These viruses have been associated with upper respiratory infections and sometimes pneumonia in humans. SARS presents with fever, cough, malaise, dyspnea, and hypoxemia. Chest radiographs from affected regions are associated with progressive airway disease. Clinical laboratory features of SARS include lymphopenia, thrombocytopenia, and elevated lactate dehydrogenase levels. Currently, there is no FDA approved pharmacologic treatment for SARS. To date, no convincing clinical data is available for treatment of SARS with ribavirin. While there are some controversies about the use of systemic corticosteroids, Martin et al, in this issue of MSM, present their views on the use of pentoxyfylline (PTX) as a potential agent to be considered for SARS treatment. Finally, our analytical approach to the risks of SARS will certainly enable us to

Severe acute respiratory syndrome (SARS) is a recently described infectious entity with salient features of fever, headache and malaise, with rapid progression to pneumonitis. The etiology of SARS is likely a novel coronavirus. During the winter of 2003, an outbreak of SARS involving several hospitals occurred in Toronto, Canada. We describe a patient post liver transplant who contracted SARS and died during the outbreak, with subsequent infection of family and several health-care workers. A novel coronavirus was detected in respiratory specimens by PCR. Due to the potential severity of SARS in transplant recipients and the large number of cases of SARS in the community, in order to avoid transmission of SARS from a donor, we developed guidelines for SARS screening of organ donors. A screening tool based on potential hospital SARS exposure, clinical symptoms, and epidemiological exposure was used to stratify donors as high, intermediate or low risk for SARS. As SARS spreads throughout the world, it may become an increasingly significant problem for transplant patients and programs.

Severe acute respiratory syndrome (SARS) is caused by a recently identified Coronavirus (SARS-CoV). The clinical symptoms are non-specific and during the first few days in particular, are not clinically distinguishable from those of many other viral or bacterial infections. The majority of infected patients develop pneumonia within a week of the first symptoms appearing. Since November 2002 the virus has spread from South China to almost 30 other countries, where about 8500 infected individuals have been registered; about 800 people have already died from the disease (9.5%). The number of infected persons includes a noticeably high percentage of health workers. This fact underlines the importance of good infection prevention measures for each patient contact. The implementation of hygienic measures requires attention, because the infection of personnel in Toronto hospitals still occurred after the virus and transmission routes were known. It appears that transmission can be prevented with relatively simple precautions, as long as these are consistently implemented. Early recognition and isolation of a possible source are an essential part of this. SARS is a group A notifiable disease (report if suspected). In the Netherlands the general practitioner has a prominent role in assessing and treating individuals who are infected or might be infected with SARS-CoV. A protocol and a detailed action plan are available. In addition to this hospitals should be prepared for the initial reception of a patient with SARS, who presents directly to the outpatients' clinic or Casualty Department.

SARS is a new kind of pneumonia. From the end of 2002 to the beginning of 2003, SARS broke in Guangdong province, Hong Kong and Beijing, and then gradually spread to the world. SARS is extremely contagious. The symptoms of SARS progress very quickly. SARS smashes the people's tranquil life and many people live in horror, worry and anxiety. But if we review the medical history of pneumonia, we would have a better understanding of SARS. This article focuses the history of people's understanding of pneumonia on the historical documents, diagnosis, etiology and treatment. Through the epidemic of SARS, the author hopes to express that contagion will live with us for a long time, but it is not a deadly disease. It is preventable and good care is essential for contagious patients. As Chinese people, we should have the best use of TCM in our combat with contagion.

Severe acute respiratory syndrome (SARS) poses a major threat to the health of people worldwide. We performed a retrospective case series analysis to assess clinical outcome and identify pretreatment prognostic correlates of SARS, managed under a standardized treatment protocol. We studied 127 male and 196 female patients with a mean age of 41+14 (range 18-83). All patients, except two, received ribavirin and steroid combination therapy. In 115 (36%) patients, the course of disease was limited. Pneumonitis progressed rapidly in the remaining patients. Sixty-seven (21%) patients required intensive care, and 42 (13%) required ventilator support. Advanced age, high admission neutrophil count, and high initial lactate dehydrogenase level were independent correlates of an adverse clinical outcome. SARS-associated coronavirus caused severe illnesses in most patients, despite early treatment with ribavirin and steroid. This study has identified three independent pretreatment prognostic correlates.

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.

Two cases of severe community-acquired pneumococcal pneumonia (CAP) admitted to our hospital within 24 h are described, both in young males. These two cases illustrate the usefulness of the British Thoracic Society severity criteria and serve to emphasize the importance of early recognition of adverse physiology in critically ill patients. We should not lose sight of the continued impact of pneumonia in this climate of widespread fear about severe acute respiratory syndrome (SARS).
