Title: Is the SARS virus mutating? Cord-id: armpejd2 Document date: 2003_6_10
ID: armpejd2
Snippet: Viruses such as HIV and those that cause influenza have often been described as 'wily' because they mutate rapidly, a trait that helps them to evade drugs or the human immune system. But so far, the SARS virus seems remarkably invariant: the genome sequences of 14 isolates from patients in Singapore, Toronto, China and Hong Kong have not revealed any changes of real consequence(17).
