Mystery deepens over SARS key TANYA TALAGA MEDICAL REPORTER "While it was announced early last week that the genetic code of the SARS virus had been cracked by a British Columbia team, Dr. Frank Plummer said his microbiology lab in Winnipeg has found the coronavirus in only about 40 per cent of the samples taken from probable SARS patients in Toronto. The link between SARS and the coronavirus is quite weak in the Canadian data," Plummer, scientific director of Canada's national microbiology lab in Winnipeg, said during a teleconference call. "In my mind and the mind of my colleagues at Health Canada, the link is not clear yet." The mystery is further complicated because in Toronto, the SARS cases are "all linked and they all should have the same thing" and "you'd expect to find some evidence of this coronavirus," said Plummer. "And that's just not the case." Except for a case in Alton Towers, a condo complex in the city's north end, SARS cases can be traced back to the original cluster. While health officials have yet to make a connection in that one case, Dr. James Young, Ontario's commissioner of public security, stressed officials continue to look for one. Plummer did admit it's possible they are looking in the "wrong place" for virus samples, which they collect from the nasopharynx, the area of the upper throat that lies behind the nose. "(But then that) would be odd because it's thought to be transmitted through the respiratory route," he said. thestar.com
