Virus: Further Research
The completion of the genomic sequence in just a few weeks have opened many doors in development of vaccines, antiviral compounds, diagnostic tests and ways to control the spread of SARS. The genomic sequence has also helped tremendously in identifying the origin of the virus. Content OutlineBelow all content of this page is listed by header title.

Stability and resistanceResearchers have evaluated the SARS-CoV's stability and resistance to environmental factors and disinfectants. For 21 days in temperatures at 4°C and -80°C, the concentration of the virus reduced at a very minimal amount. This indicates that the virus is more stable than other human coronaviruses. Yet, when heated to 56°C, the SARS-CoV becomes inactive. The same happens when the SARS-CoV reacts to commonly used disinfectants. Natural hostIn Hong Kong and Shenzhen, researchers have studied six civets from a southern Chinese market, and discovered that the coronaviruses found in these animals, were almost identical to the SARS coronaviruses in humans. The coronavirus were detected by a PCR molecular technique. More specifically, the SARS coronaviruses were found in the serum where SARS growth took place. The only difference between the coronaviruses in humans and in the animals was a small additional sequence in the animals. Because of this revelation, thousands of civet cats are being destroyed in China, against WHO's (World Health Organization) wishes. The WHO was dismayed because the civets cats could provide further research on the virus, yet China fears further spreading. Interactive

Further Research
The completed genomic sequence show that although the SARS-CoV displays clear features of a typical coronavirus, there are
also features that place it in a new category, far from all the previous coronaviruses. Thus, the WHO (World Health
Organization) named it the 'novel' coronavirus.
