(CIDRAP News) The US Centers for Disease Control and Prevention (CDC) today confirmed two more novel flu infections, one an H3N2 variant that has been identified in 11 other patients this year and one an H1N1 variant that has never been reported in humans before.
(CIDRAP News) The unusual spring emergence and summer activity of the novel H1N1 virus in 2009 led suspicions that its transmission pattern might vary from seasonal strains, but new research suggests that it was similar to seasonal H3N2 viruses.
May 29, 2008 (CIDRAP News) With summer temperatures settling in across the United States, health authorities are conceding that the novel H1N1 flu virus may continue circulating through the summer, rather than quieting down as seasonal flu strains do.
