SARS virus identified, scientists say
OTTAWA - Scientists at the University of Hong Kong say they have identified the virus behind the mystery illness known as severe acute respiratory syndrome (SARS).

They say this discovery will allow them to diagnose and treat the illness much faster than before.
In the meantime, Ottawa is dealing with its first suspected case of SARS. A 56-year-old man is under observation and quarantine at the Queensway-Carleton Hospital; and the medical officer of health says he expects more cases will follow.
Dr. Robert Cushman says the spread of SARS in Toronto made it inevitable that possible cases could appear here.

INDEPTH: Severe Acute Respiratory Syndrome
Notice of the first such case in Ottawa came Tuesday, from staff at Queensway-Carleton.
The patient has been isolated. Family members and some hospital staff are also being closely watched, to see if they develop similar symptoms.
Dr. Cushman says the common flu-like symptoms of SARS mean more investigations likely will have to be launched.
"We will identify cases who meet these very loose criteria, and obviously err on the side of caution. So I suspect we will have more."
Because there is no test for SARS, doctors can only identify it by ruling out other possible diseases.
It could take up to 10 days to determine if the patient at Queensway-Carleton has this potentially deadly illness.
Dr. Cushman says the health department may designate a building in Ottawa where it can quarantine possible SARS cases.
Hong Kong researchers identify virus
In Hong Kong, researchers identified SARS, or severe acute respiratory virus, as a new "corona" virus which is similar to a common cold virus.
The breakthrough is believed to make way for a SARS test, that could be available in Hong Kong hospitals by Friday.
One of the tests will detect the virus's antibodies, the body's immune response to the virus's presence, and one will test for the genes contained in the virus.
The discovery also resulted in a change in the name of the disease, from SARS to coronal viral pneumonia.
The government of Hong Kong is ordering the quarantine of more than 1,000 people to prevent the spread of the disease. As well, all primary and secondary schools will be closed until April 6.
Ten people in Hong Kong have died from the atypical pneumonia.
The death toll from the disease rose sharply, Wednesday, with updated reports from China.
There are now 1,334 cases of SARS, leading to 49 deaths, three of those in Canada.
SARS first arrived in Toronto a month ago, when a woman returned from a trip to Hong Kong. She died from the ailment.
Toronto's medical officer of health said the city has the largest outbreak of SARS outside of Asia, and thousands of people are expected to go under a 10-day house quarantine.
