  • SWINE INF FINAL - OIE

    2021-5-6 · A biosecurity plan for swine influenza must identify potential pathways for the introduction and spread of disease. Because swine influenza virus is spread predominantly through the respiratory route, and is highly transmissible between pigs, effective biosecurity can be difficult to achieve.

    2011-12-24 · Reassortant H1 swine influenza viruses (SIVs) carrying 2009 pandemic H1N1 virus (pH1N1) genes have been isolated from pigs worldwide. Seven novel reassortant H3N2 SIVs were identified from diseased pigs in the USA from winter 2010 to spring 2011. These novel viruses contain three or five internal genes from pH1N1 and continue to circulate in swine herds.
