Novel Influenza A Virus:
One infection with an influenza A (H3N2) variant virus (H3N2v) was reported to CDC during week 47 from Iowa.
While no contact with swine or other livestock in the week preceding illness was reported, investigation into potential additional sources of infection is ongoing.
No further cases have been identified in contacts of the case patient.
This is the first H3N2v infection reported since September 28, 2012.
A total of 311 infections with variant influenza viruses (307 H3N2v viruses, 3 H1N2v viruses, and 1 H1N1v virus) have been reported from 11 states from July 2012 through November 28, 2012.
More information about H3N2v infections can be found at http://www.cdc.gov/flu/swineflu/h3n2v-outbreak.htm.
The vast majority of variant virus infections have occurred after exposure to swine, though instances of likely human-to-human transmission have been identified.
No ongoing human-to-human transmission has been identified.
