Everyone is not buying it. The article below suggests that the number of patients positive for SARS CoV sequences is now 12 and includes patients from both nursing homes (Kinsmen Lodge Place and a 101 bed facility, which is almost certainly Kinsmen Retirement Centre in Delta). 750/750 matches means the sequences are from SARS CoV. The question is whether the sequences are from patients of the nursing homes, or repeated contamination by the Winnipeg lab. After reporting 8 positives, its hard to believe that contamination would be involved in 4 more. The Winnipeg lab knows that there is worldwide interest in their results and have to be aware of the consequences of continuing to generate false positives because of contamination. It certainly looks like some require more than a finding of OC43 coronavirus in some samples. Some samples were also positive for meta-pneumovirus. Nether OC43 nor meta-pneumovirus detection explains the SARS CoV sequences. Its contamination or its SARS (or SARS recombinant or mutant). The sequence data are not due to cross reactivity with OC-43 or any other closely related cold coronavirus. >===== Original Message From "Henry L Niman, PhD" <henry_niman@hms.harvard.edu> ===== straitstimes.asia1.com.sg Vancouver Sars denial a cause for concern By Andy Ho
