The SARS coronavirus appears to be different from all other known coronaviruses, including animal ones.
SARS, researchers are homing in on two particular types of virus, coronaviruses and metapneumoviruses.
But this new virus is different from any coronaviruses previously identified in humans.
Coronaviruses are a family of viruses ranging from the common cold to the Sars (severe acute respiratory syndrome) virus.
Coronaviruses are a group of viruses ranging from the common cold to the Sars (severe acute respiratory syndrome) virus.
But the unit deepened scientific understanding of the condition, isolating coronaviruses and rhinoviruses, two of the most frequent causes of colds.
In this they resemble the three groups of coronaviruses already known to cause animal and human diseases, among them the common cold.
There are a number of vaccines on the market to combat coronaviruses in chickens and cattle, as well as pigs, cats and dogs.
But it could turn out to be a mutation or cross strain of one or several coronaviruses seen in cows, birds and pigs.
Coronaviruses, which are common around the world, often cause colds.
Veterinary doctors say some coronaviruses cause no symptoms at all.
And although media reports usually mentions the new virus and SARS in the same breath it is worth pointing out that coronaviruses also produce infections like the common cold.
Coronaviruses are a large family of viruses ranging from the common cold to the Sars (severe acute respiratory syndrome) virus, spread through droplets of body fluids produced by sneezing and coughing.
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.
Coronaviruses have apparently jumped species before: Dr. Konstantin "Gus" Kousoulas, a professor at Louisiana State University who studies coronaviruses in cattle, published a paper back in 1993 describing a bovine-like coronavirus strain in a child in Germany.
And in the past week, two groups of geneticists, one at the Michael Smith Genome Sciences Centre in Vancouver, British Columbia, and the other at the Centres for Disease Control and Prevention in Atlanta, Georgia, have succeeded in sequencing the genomes of coronaviruses isolated from patients in Toronto and Asia.
