Introduction[edit | edit source]
Severe acute respiratory syndrome (SARS) is a viral respiratory disease caused by a SARS-associated coronavirus. It was first identified at the end of February 2003 during an outbreak that emerged in China and spread to 4 other countries.
- Airborne virus and can spread through small droplets of saliva in a similar way to the cold and influenza. It was the first severe and readily transmissible new disease to emerge in the 21st century and showed a clear capacity to spread along the routes of international air travel.
- Can also be spread indirectly via surfaces that have been touched by someone who is infected with the virus.
- Most patients identified with SARS were previously healthy adults aged 25–70 years[1].

Etiology[edit | edit source]
SARS-CoV is thought to have jumped from an animal reservoir in the horseshoe bat through an intermediate host in the palm civet and then to humans.
- Coronaviruses are named for their crown-like glycoprotein spikes on their surface.
- Coronaviruses are large single-stranded RNA viruses that have helical nucleocapsids.
- They are usually associated with humans with the common cold, though, and in animals, they’re linked with a highly virulent disease[2]
