CDC confirms two more novel flu infections

The U.S. Centers for Disease Control and Prevention confirmed two more novel flu infections on Friday - an H3N2 variant identified in 11 other patients this year and an H1N1 variant never before reported in humans.
The H3N2 case involves a swine-origin H3N2 reassortant strain including the M gene from the 2009 H1N1 pandemic virus and was reported in a West Virginia child. The H1N1 virus is a triple-reassortant that acquired the M gene from the 2009 H1N1 virus that sickened an adult in Wisconsin who had occupational contact with swine and has recovered, CIDRAP News reports.
The West Virginia child is a daycare contact of another child whose novel H3N2 infection was reported on December 9. The second child got sick on November 29 with symptoms including cough, fever, rhinorrhea and diarrhea. The child did not seek medical care and has fully recovered.
The CDC said that no other cases have been detected at the daycare or among the two children's contacts, according to CIDRAP News. While the two infections in West Virginia occurred in children who attended the same daycare, the CDC said that the first child probably didn't transmit the virus to the second child. Surveillance by the organization suggests that the novel H3N2 virus is also circulating in swine herds.
The novel H1N1 virus contains genes from avian, swine and human flu viruses. A review of genome sequencing databases suggests that the variant has been found in U.S. swine since 2010, though the case is the first to detect such a strain in humans.
