Severe Acute Respiratory Syndrome


***** epidemic created a medical emergency and a healthcare crisis with the loss of hundreds of lives in a short sp*****n of time. The knowledge of the etiology of ***** disease and the genome sequence of ***** virus provided new impetus in treatment of the *****. The crisis was successfully managed through an international cooperative effort and today we are better prepared to handle possible future outbreaks of the epidemic.


SARS is an acute infectious respiratory d*****ease ***** all the symptoms of atypical pneumonia like fever, breathlessness that caused severe casualties in a short period of *****. The first *****stance ***** SARS infection was reported in November 2002 ***** ***** Guangdong province of china. The SARS epidemic ***** a panic worldover and the World Health Organization issued a global alert on March 12th 2003 about the rapid spread of symptoms of atypical *****. Symptoms of atypical pneumonia were reported in China and Hong Kong in February ***** March of ***** and SARS created ***** at ***** global level with 774 deaths and more than 8000 infected people. China, Taipei, Canada and Hong ***** suffered the most from the epidemic while sporadic ***** infections ***** found in many European nations and North America. Hundreds of people exhibiting ***** were quarantined ***** treated for the complications until the SARS outbreak was fully contained. In July 2003 China officially announced ***** successful ***** of the last 12 cases of SARS. The present problem however is the early detection ***** the virus as the currently available diagnostic tools are ei*****r time consuming (ELISA and Immunofluorescence) or highly sensitive without any conclusive detection. (PCR). A discussion of the epidemiology, transmission, and the latest research results and treatment methods would provide a better underst*****nding ***** the disease.

***** S*****RS Virus

Ever since ***** ***** of the epidemic in February ***** lab*****atories worldwide were *****volved in research to hasten ***** identification of the agent that was responsible for the symptoms of ***** pneumonia. The ***** health organization instituted a combined research by eleven laboratories on ***** 17th to speedup the research, as by then, the ***** was starting to take its toll. By ***** end ***** March *****ers in ***** Kong managed to find out traces of a novel coronavirus in the affected patients. By means ***** cell culture, electron microscopy and immuno-fluroscent antibody tests researchers ***** United States and Germany also confirmed the existence of a special type of coronavirus. Coronavirueses have the largest genome size ranging from 27 kb ***** 32 kb and ***** been well known to cause respiratory disorders in animals. Coronoviruses are easily transmitted by way of droplets, touch and small particulates in the air. They also have very ***** incubation periods as is ***** case with the SARS virus which has an incubation period between 2 and 7 days. On April *****th 2003 scientists working at the Michael Smith Genome Sciences center sucesfully mapped out ***** genetic sequence of the SARS virus making ***** for
