September 26, 2012 Scientists have partially decoded the genetic sequence of a new virus, which has killed one man and hospitalized another. Advances in sequencing technologies have helped health workers rapidly respond to the virus in ways that they couldn't during the SARS epidemic of 2002.
September 24, 2012 A virus, which is genetically different than any seen before, has killed one man and hospitalized another. The virus comes from the same family as SARS, but it appears to be less contagious.
