Monday, September 08, 2003Count the mutations, geneticists say, and you can figure out how far removed this new virus is from its ancestor. 'The common link between those two is about a year ago,' when separation likely occurred between the virus in animals from the one infecting humans, said Earl Brown, a virologist at the University of Ottawa. And it's highly possible that the virus has passed back and forth many times among animals and humans in the market that sells these exotic animals, he says. 'If it was bumping back and forth between people and animals a year ago then it probably wasn't making people that sick. But that's all part of the natural history of SARS, which we don't have together. Still so much to learn. posted by Sydney on 9/08/2003 08:38:00 AM 0 comments 0 Comments: |
