The SARS coronavirus appears to be different from all other known coronaviruses, including animal ones.
In 2002 an outbreak of the Sars coronavirus killed about 800 people after it spread from Hong Kong to more than 30 countries around the world.
"The 'super-spreading' events, in which one person infects several dozen people at a time (as was seen with SARS coronavirus), do not seem to be happening with this coronavirus" said Prof Peter Openshaw, Director of the Centre for Respiratory Infection, Imperial College London.
In animals, as we've seen in SARS, some coronavirus patients die while others make a full recovery.
The suspect behind SARS, a coronavirus, is smaller than that but comes encased in water droplets that get caught outside the mask.
The WHO said that, unlike Sars, the new coronavirus, "does not appear to transmit easily between people".
Experiments carried out at Erasmus University in the Netherlands have shown that a coronavirus taken from SARS patients produces SARS-like symptoms in monkeys.
These secure Web sites have played a pivotal role in beginning to understand the coronavirus that causes SARS, and in beginning to identify which patients are at the highest risk of dying from the pneumonia.
The SARS virus is most probably a coronavirus, the type of virus responsible for up to 30% of common colds.
The new virus is a coronavirus with similar symptoms to SARS (Severe Acute Respiratory Syndrome), which emerged in China in 2002 and killed around a 10th of the 8, 000 people it infected worldwide.

Although the novel coronavirus is from the same large family of pathogens as SARS, it is very different.
Bats may be the source of a new Sars-like virus which killed a man in Saudi Arabia, according to an analysis of the coronavirus' genome.
Novel coronavirus is part of a family called coronaviruses, which cause illnesses ranging from the common cold to SARS, or Severe Acute Respiratory Syndrome, as well as a variety of animal diseases.
