The objectives of this research study are: 1. To probe into the widespread period of severe acute respiratory syndrome. 2. To study on this highly contagious and rapid spread of this new kind of disease At the time when nearby emergency department of medical center breaks out a suspicion of nasocomial infection. First, our emergency department immediately formed a strict fever screening station. After comparing the outcome of the prevention and spreading of this disease by the set-up of the emergency fever station between the central and southern medical institution. The research period was from May 15, 2003to July 15, 2003. Our research targets made by the emergency fever station were around 3730 patients with a random selection of 300 cases. This research uses the structure of fever screening measurement questionnaires to gather information and then adapted the EP1-INFO 10.0 version of statistical analysis. The results of the research are as follows: 1. Chief complaint of sore throat (38.3%) and fever (17%) fitted to the clinical symptoms of SARS. In relation to SARS before and after the spread of the disease, there are still other complaints such as the gastrointestinal system (18.7%) and cardiovascular disease (16.7%) that showed no obvious difference. 2. During the period of emergency fever screening station, an additional 50% of manpower are being arranged to screen probable or non-probable affected cases. (from the 300 randomly selected cases) 3. There are no obvious difference showed after comparing the outcome of the prevention and spreading of this disease by the set-up of the emergency fever center between the central and southern medical institution. 4. After tallying the number of doctors and nurses participated in screening procedure and number of non-medical staff developed similar symptoms to SARS, we can see the result of total number of medical staff from the emergency fever screening station that can successfully control the spread and prevention of the disease, making it the standard and model in the prevention and control of other communicable disease in the future.
