CDC Tracking Cases Of Drug-Resistant “Dual Mutant” H1N1 Influenza

CBS News (6/12, Tin) reports, “At least two human cases of the new so-called ‘dual mutant’ strains of H1N1 influenza have been detected in U.S. patients, the Centers for Disease Control and Prevention said Wednesday, with genetic changes that could cut the effectiveness of the main flu antiviral that hospitals rely on.” A study investigating “the new H1N1 flu viruses with these two concerning mutations – which scientists call I223V and S247N, describing changes to key surface proteins of the virus – was published this week in the agency’s Emerging Infectious Diseases journal.”
