The severe acute respiratory syndrome SARS coronavirus S protein mediates infection of permissive cells through interaction with its receptor, the angiotensin-converting enzyme 2 ACE 2and monoclonal antibody to the S1 domain was found to neutralize the virus by blocking its association with the receptor ACE 2. Also the fusion of the SARS coronavirus with the cell could be considered an attractive target. To the extent that this fusion process bears resemblance to the fusogenic mechanism of HIV, i.

The virus was also later found in raccoon dogs Nyctereuteus sp.SARS, or Severe Acute Respiratory Syndrome, is a respiratory condition that first came to light in SARS cases occurred in different continents during . Severe acute respiratory syndrome (SARS) is caused by the SARS coronavirus, known as SARS CoV.

Coronaviruses commonly cause infections in both humans and animals. There have been two self-limiting SARS outbreaks to date, which resulted in a highly contagious and potentially life threatening form of pneumonia.

Infection with the SARS virus causes acute respiratory distress (severe breathing difficulty) and Severe acute respiratory syndrome (SARS) Infection with the SARS virus causes acute respiratory distress (severe breathing difficulty) and sometimes death.

Topic Overview

SARS is a dramatic example of how quickly world travel can spread a disease. It is. sources of the virus include the original animal reservoir or other SARS-infected animals, unrecognized transmission in humans, or persistent infection in humans.

Since other respiratory viruses are seasonal, it is possible that SARS may be more likely to reestablish infection and spread during respiratory virus season: fall, winter, and spring.
