In April, when Canadian scientists sequenced the genetic code of the SARS virus, they discovered a microbe unlike any other ever seen in humans or animals. On its genome "there is a long stretch of nucleotides and then one big piece that sticks out," says University of Hong Kong microbiologist Malik Peiris, who first linked SARS to a novel coronavirus. "When we then looked to see if antibodies for it exist in human blood samples, there were none."
